"Robot Learning: Towards Real World Applications"

Thursday, May 19th @ 11AM PDT (Virtual)

Zoom:  https://ucsd.zoom.us/j/96737331505

Speaker:  Stefan Schaal, Google X, Intrinsic

Machine learning for robotics, particularly in the context of deep learning and reinforcement learning, has demonstrated remarkable results in recent years. From the viewpoint of reliability and robustness of performance, however, there is a significant gap between improving a robotic skill, i.e. to just get better, vs. actually achieving reliability, which is often expressed in success rates clearly above 99%. From experience in the past, reliability requires to exploit the best of all ingredients that are needed in a robotic skill, e.g., including control, perception (vision, force, tactile, etc.), and machine learning. This talk will touch on various related topics that we have been pursuing in recent years, including interesting challenge domains for robot manipulation, exploiting impedance control for contact rich manipulation, deep learning for various perception tasks, and meta reinforcement learning to learn new manipulation skills in fractions of an hour with close to 100% success rate.

Zoom Linkhttps://ucsd.zoom.us/j/96958677518

Speaker:  Russ Tedrake

In this talk, I'll describe a new approach to planning that strongly leverages both continuous and discrete/combinatorial optimization.  The framework is fairly general, but I will focus on a particular application of the framework to planning continuous curves around obstacles. Traditionally, these sort of motion planning problems have either been solved by trajectory optimization approaches, which suffer with local minima in the presence of obstacles, or by sampling-based motion planning algorithms, which can struggle with derivative constraints and in very high dimensions.  In the proposed framework, called Graph of Convex Sets (GCS), we can recast the trajectory optimization problem over a parametric class of continuous curves into a problem combining convex optimization formulations for graph search and for motion planning.  The result is a non-convex optimization problem whose convex relaxation is very tight — to the point that we can very often solve very complex motion planning problems to global optimality using the convex relaxation plus a cheap rounding strategy.  I will describe numerical experiments of GCS applied to a quadrotor flying through buildings and robotic arms moving through confined spaces.  On a seven-degree-of-freedom manipulator, GCS can outperform widely-used sampling-based planners by finding higher-quality trajectories in less time, and in 14 dimensions (or more) it can solve problems to global optimality which are hard to approach with sampling-based techniques.

"On the Question of Representations in Robotics"

Thursday, April 21st @ 11am PDT (Virtual)

Zoom:  https://ucsd.zoom.us/j/92110938804

Speaker:  Jeannette Bohg, Professor for Robotics, Stanford University

General-purpose autonomous robots cannot be preprogrammed for all the tasks they will be required to do. Just like humans, they should be able to acquire new skills and adapt existing ones to novel tasks and contexts. One approach is to develop general-purpose, task-independent representations of semantic entities needed in these aforementioned tasks. Representations like this promise effectiveness through compression of a lot of information into a single symbol, which then is able to generalise to all possible situations and contexts.

However, in my work I have yet to encounter general-purpose, task-independent representations that enable robust decision-making on a robot. Even if working with learned representations, the learning process, objectives and model architectures are at least in part task-specific.

In this talk, I will discuss three of my research projects that each employ different representation learning techniques to enable physical interaction with an environment. First, I will discuss our work that uses self-supervision to learn a compact and multimodal representation of visual and haptic sensory inputs, which can then be used to improve the sample efficiency of deep reinforcement learning.  I present experiments on a peg insertion task where the learned representation generalises over different geometry, configurations, and clearances, while enabling the policy to being robust to external perturbations. Second, I will discuss our recent work on learning to manipulate deformable objects where we represent the visual data using learned key point representations. Specifically, we show how these key points enable learning from human video demonstrations in an active learning setting. And third, I will present work on using an environment representation that is learned through self-supervision for closed-loop navigation. Specifically, I will show how we can use Neural Radiance fields to enable closed-loop navigation of a robot equipped only with an RGB camera.

The commonality in all these works is that they employ learned representations trained through self-supervision. I will close the talk by discussing the lessons learned, opportunities I see and open questions on what desirable characteristics of representations in robotics may be.

"Online Mobile Robot Motion Planning and Trajectory Control Under Uncertainty in Partially-known Environments"

Thursday 7th April 2022 @ 11AM PST in Atkinson Hall, Room 5004 and on Zoom (i.e. in person with a zoom backup)

Zoom Meeting:  https://ucsd.zoom.us/j/97819733919

Speaker:  Dr. Konstantinos Karydis, UCR 

Mobile robot motion planning and trajectory tracking control under uncertainty is a challenging yet rewarding foundational robotics research problem with extensive applications across domains including intelligence, surveillance and reconnaissance (ISR), remote sensing, and precision agriculture.  One important challenge is operation in unknown or partially-known environments where planning decisions and control input adaptation need to be made at run-time.  In this talk we consider how to address two specific cases:  1) How to achieve resolution-complete field coverage considering the non-holonomic mobility constraints in commonly-used vehicles (e.g., wheeled robots) without prior information about the environment?  2) How to develop resilient, risk-aware and collision-inclusive planning and control algorithms to enable (collision-resilient) mobile robots to deliberately choose when to collide with locally-sensed obstacles to improve some performance metrics (e.g., total time to reach a goal). 

To this end, we have proposed a hierarchical, hex-decomposition-based coverage planning algorithm for unknown, obstacle-cluttered environments.  The proposed approach ensures resolution-complete coverage, can be tuned to achieve fast exploration, and plans smooth paths for Dubins vehicles to follow at constant velocity in real-time.  Our approach can successfully trade-off between coverage and exploration speed, and can outperform existing online coverage algorithms in terms of total covered area or exploration speed according to how it is tuned.  Further, we have introduced new sampling- and search-based online collision-inclusive motion planning algorithms for impact-resilient robots, that can explicitly handle the risk of colliding with the environment and can switch between collision avoidance and collision exploitation.  Central to the planners’ capabilities is a novel joint optimization function that evaluates the effect of possible collisions using a reflection model.  This way, the planner can make deliberate decisions to collide with the environment if such collision is expected to help the robot make progress toward its goal.  To make the algorithm online, we present state expansion pruning techniques that can significantly reduce the search space while ensuring completeness.

"Animal and Robot Locomotion in Complex 3-D Terrain"

Thursday, March 31 @ 11am PST (Virtual)

Join Zoom Meeting
https://ucsd.zoom.us/j/94266860659

Faculty Host: Nick Gravish

Mobile robots must move through complex environments in many applications. A highly successful approach is to create geometric maps of the environment and plan and follow a collision-free, safe trajectory to avoid sparse large obstacles, as exemplified by self-driving cars. However, many crucial applications require robots to traverse complex 3-D terrain with cluttered obstacles as large as themselves, such as search and rescue in rubble, environmental monitoring in forests and mountains, and sample collection in extraterrestrial rocks. Although many animals traverse such complex 3-D terrain at ease, bio-inspired robots are still poor at doing so. This is largely due to a lack of fundamental understanding of how to use and control physical interaction with such terrain to move through. Here, I review my lab’s progress towards filling this gap by integrating animal experiments, robot experiments, and physics modeling.

In the first half of the talk, I will discuss work on locomotor transitions of insects and multi-legged robots. Previous studies of multi-legged locomotion largely focused on how to generate near-steady-state walking and running on relatively flat surfaces and how to stabilize it when perturbed. By contrast, multi-legged locomotion in complex 3-D terrain occurs by stochastically transitioning across stereotyped locomotor modes. A potential energy landscape approach revealed surprising general principles for a diversity of locomotor challenges encountered in such terrain—why these modes occur, and how to transition across them.

In the second half, I will discuss work on limbless locomotion of snakes and snake robots. Previous studies of limbless locomotion largely focused on how to move on relatively flat surfaces with sparse vertical structures as anchor points for stability or push points for propulsion. By contrast, limbless locomotion in 3-D terrain benefits from coordinated lateral and vertical body bending, which not only helps conform to the terrain for stability, but also provides access to many more push points for propulsion.

For both directions, we are currently working on how to sense physical interaction during locomotion and use feedback control to enable autonomous locomotion across complex 3-D terrain.

Generalization in embodied intelligence, such as in robotics, requires interactive learning across families of tasks is essential for discovering efficient representation and inference mechanisms. Concurrent systems need a lot of hand-holding to even learn a single cognitive concept or a dexterous skill, say “open a door”, let alone generalizing to new windows and cupboards! This is far from our vision of everyday robots! would require a broader concept of generalization and continual update of representations.
My research vision is to build the Algorithmic Foundations for Generalizable Autonomy, which enables robots to acquire skills in cognitive planning & dexterous interaction, and, in turn, seamlessly interact & collaborate with humans. This study of the science of embodied AI opens three key questions: (a) Representational biases & Causal inference for interactive decision making, (b) Perceptual representations learned by and for interaction, (c) Systems and abstractions for scalable learning.

This talk will focus on decision-making uncovering the many facets of inductive biases in off-policy reinforcement learning in robotics. I will introduce C-Learning to trade off-speed and reliability instead of vanilla Q-Learning. Then I will talk about the discovery of latent causal structure to improve sample efficiency. Moving on from skills, we will describe task graphs for hierarchically structured tasks for manipulation. I will present how to scale structured learning in robot manipulation with Roboturk, and finally, prescribe a practical algorithm for deployment with safety constraints. Taking a step back, I will end with notions of structure in Embodied AI for both perception and decision making.

Emerging surgical paradigms such as natural orifice surgery and minimally invasive surgery in deep surgical sites present new challenges to surgeons and engineers. These new challenges stem from the limitations of surgeon’s sensing, perception, and incomplete situational awareness. The speaker will present the concept of complementary perception and assistive behaviors as a means for increasing safety and overcoming these barriers. He will discuss how continuum robots and soft implantable devices can be endowed with distal tip force sensing, contact detection, and micron-scale motion resolution that enables in-vivo deployment of cellular scale imaging modalities such as optical coherence tomography. We will focus on our efforts in modeling, designing and controlling intelligent surgical robots capable of sensing the environment and using the sensed information for task execution assistance and for situational awareness augmentation. Sample motivating applications in the areas of minimally invasive surgery of the upper airways, cochlear implant surgery, trans-urethral resection of bladder tumors, and OCT-guided retinal micro-surgery will be used to elucidate the potential of these robots. Finally, recent applications of continuum robots for collaborative manufacturing for safe physical human-robot interaction will be presented as an extension of the theoretical work done initially for surgical applications into a different application domain.

"Rich Babies, Poor Robots: Towards Rich Sensing, Environments and Representations"

Speaker:  Abhinav Gupta

In recent years, we have seen a shift in different fields of AI such as computer vision, robotics. From task-driven supervised learning, we are now starting to see shift towards more human like learning. Self-supervised learning, embodied AI, multimodal learning are few subfields which have emerged from this shift. Yet I will argue the shift is half-hearted in nature and there is a huge situational gap between babies (human learners) and current robots. Our babies use five senses, multiple environments and rich forms of supervision. On the other hand, our AI algorithms still primarily use vision (best case), learn for pre-defined tasks and use categories as supervision. In this talk, I will argue how to bridge this gap. First, I will talk about how to bring tactile sensing into mainstream. More specifically, I will introduce our magnetic sensing skin called ReSkin. Next I will talk about how to formulate task-agnostic learning to learn from multiple environments. Finally, I will talk about using human functions as supervision to train representations.

Speaker:  Angela Schoellig

To date, robots have been primarily deployed in structured and predictable settings, such as factory floors and warehouses. The next generation of robots -- ranging from self-driving and -flying vehicles to robot assistants - is xpected to operate alongside humans in complex, unknown and changing environments. This challenges current robot algorithms, which are typically based on our prior knowledge about the robot and its environment. While research has shown that robots are able to learn new skills from experience and adapt to unknown situations, these results have been limited to learning single tasks in simulation or structured lab settings. The next challenge is to enable robot learning in real-world application scenarios. This will require versatile, data-efficient and online learning algorithms that guarantee safety. It will also require to answer the fundamental question of how to design learning architectures for interactive agents.

In this talk I will do two things : First, I will give you an overview of our recent survey paper on Safe Learning in Robotics, which you can find here : https://arxiv.org/abs/2108.06266. Second, I will highlight our recent progress in combining learning methods with formal results from control theory. By combining models with data, our algorithms achieve adaptation to changing conditions during long-term operation, data-efficient multi-robot, multi-task transfer learning, and safe reinforcement learning. We demonstrate our algorithms in vision-based off-road driving and drone flight experiments, as well as on mobile manipulators.

"Deploying autonomous vehicles for micro-mobility on a university campus"

Thursday 13 January @ 11AM PST

Join Zoom Meeting:  https://ucsd.zoom.us/j/99055507432

Speaker: Henrik Christensen

Abstract: Autonomous vehicles are already deployed on the inter-states. Providing robust autonomous systems for urban environments is a different challenge, as the road network is more complex, there are many more types of road-users (cars, bikes, pedestrians, …) and the potential interactions are more complex. In an urban environment it is also harder to use pre-computed HD-maps as the world is much more dynamic. We have studied the design of micro-mobility solutions for the UCSD campus. In this presentation we will discuss an overall systems design, trying to eliminate HD-maps and replace it with course topological maps such as OpenStreet Maps, fusing vision and lidar for semantic mapping /localization, detection and handling other road-users. The system has been deployed for a 6-month period to evaluate robustness across weather, season changes, etc. We will present both underlying methods, and experimental insight.

While industrial robots are effective in repetitive, precise kinematic tasks in factories, the design and control of these robots are not suited for physically interactive performance that humans do easily. These tasks require ‘physical intelligence’ through complex dynamic interactions with environments whereas conventional robots are designed primarily for position control. In order to develop a robot with ‘physical intelligence’, we first need a new type of machines that allow dynamic interactions. This talk will discuss how the new design paradigm allows dynamic interactive tasks. As an embodiment of such a robot design paradigm, the latest version of the MIT Cheetah robots and force-feedback teleoperation arms will be presented. These robots are equipped with proprioceptive actuators, a new design paradigm for dynamic robots. This new class of actuators will play a crucial role in developing ‘physical intelligence’ and future robot applications such as elderly care, home service, delivery, and services in environments unfavorable for humans.

"Toward Object Manipulation Without Explicit Models"

Thursday 18 November @ 11AM PST (virtual)

Speaker:  Professor Dieter Fox 

 

The prevalent approach to object manipulation is based on the availability of explicit 3D object models. By estimating the pose of such object models in a scene, a robot can readily reason about how to pick up an object, place it in a stable position, or avoid collisions. Unfortunately, assuming the availability of object models constrains the settings in which a robot can operate, and noise in estimating a model's pose can result in brittle manipulation performance. In this talk, I will discuss our work on learning to manipulate unknown objects directly from visual (depth) data. Without any explicit 3D object models, these approaches are able to segment unknown object instances, pickup objects in cluttered scenes, and re-arrange them into desired configurations. I will also present recent work on combining pre-trained language and vision models to efficiently teach a robot to perform a variety of manipulation tasks.  I'll conclude with our initial work toward learning implicit representations for objects.

The animal kingdom is full of both human and non-human animals worthy of investigation, emulation and re-creation. As such, my research group has created a comprehensive research program focusing on biologically-inspired robots, and has applied them to search and rescue, minimally invasive surgery, manufacturing, and recycling. These robots inspire great scientific challenges in mechanism design, control, planning and estimation theory. These research topics are important because once the robot is built (design), it must decide where to go (path planning), determine how to get there (control), and use feedback to close the loop (estimation). A common theme to these research foci is devising ways by which we can reduce multi-dimensional problems to low dimensional ones for planning, analysis, and optimization. In this talk, I will discuss our results in geometric mechanics, Bayesian filtering, scalable multi-agent planning, and application and extension of modern machine learning techniques to support these reductions. This talk will also cover how my students and I commercialized these technologies by founding three companies: Medrobotics, Hebi Robotics, and Bito Robotics. If time permits, I will also discuss my educational activities, especially at the undergraduate level, with a course using LEGO robots, and the role of entrepreneurism in University education.

Speaker:  Paolo Pirjanian, Ph.D., Founder/CEO of Embodied and former CTO of iRobot

 

Previous solutions to HRI have taken a piecemeal approach to building a social interface and have failed. Many solutions merely copy the command-response conversation pattern, e.g., from Alexa, onto a robot which can be awkward and unnatural. Most social robots attempt to add human qualities but fall short in true social interaction: simply adding “eyes” that do not look at you is uncanny. Using a touch screen “face” as a means of input is a step backwards and poking a character’s “face” encourages inappropriate social behavior. Having a faux body but no means to express body language seems lifeless and lacks embodiment. These piecemeal solutions miss the point. Social interaction does not require perfect anthropomorphic form-factor but it does need a minimum set of affordances to have successful and believable agency, something that we can learn from Pixar, Disney and the like.

At Embodied we have been rethinking and reinventing how human-machine interaction is done - where a user can have a fluid natural conversation with a robot; and where the robot can discern who to address and how to proactively engage and use subtle eye gaze, facial expressions, and body language as part of its response.

"Beyond the Label: Robots that Reason about Object Semantics"

Zoom:  https://ucsd.zoom.us/j/94406976474

Speaker:  Professor Sonia Chernova

 

Reliable operation in everyday human environments – homes, offices, and businesses – remains elusive for today’s robotic systems. A key challenge is diversity, as no two homes or businesses are exactly alike. However, despite the innumerable unique aspects of any home, there are many commonalities as well, particularly about how objects are placed and used. These commonalities can be captured in semantic representations, and then used to improve the autonomy of robotic systems by, for example, enabling robots to infer missing information in human instructions, efficiently search for objects, or manipulate objects more effectively. In this talk, I will discuss recent advances in semantic reasoning, particularly focusing on semantics of everyday objects, household environments, and the development of robotic systems that intelligently interact with their world.

"Learning Where to Trust Unreliable Models for Deformable Object Manipulation"

Thursday, Sept. 30 @ 11AM PST 

Zoom: https://ucsd.zoom.us/j/94406976474

Speaker:  Professor Dmitry Berenson

 

The world outside our labs seldom conforms to the assumptions of our models. This is especially true for dynamics models used in control and motion planning for complex high-DOF systems like deformable objects. We must develop better models, but we must also accept that, no matter how powerful our simulators or how big our datasets, our models will sometimes be wrong. This talk will present our recent work on using unreliable dynamics models for the manipulation of deformable objects, such as rope. Given a dynamics model, our methods learn where that model can be trusted given either batch data or online experience. These approaches allow dynamics models to generalize to control and planning tasks in novel scenarios, while requiring much less data than baseline methods. This data-efficiency is a key requirement for scalable and flexible manipulation capabilities.

"Observing, Learning, and Executing Fine-Grained Manipulation Activities: A Systems Perspective"

Thursday, May 27 @ 12:00ppm PST
 

Zoomhttps://ucsd.zoom.us/j/91267376688
Speaker: Gregory D. Hager

In the domain of image and video analysis, much of the deep learning revolution has been focused on narrow, high-level classification tasks that are defined through carefully curated, retrospective data sets. However, most real-world applications – particularly those involving complex, multi-step manipulation activities -- occur “in the wild" where there is a combinatorial “long tail” of unique situations that are never seen during training. These systems demand a richer, fine-grained task representation that is informed by the application context, and which supports quantitative analysis and compositional synthesis. As a result, the challenges inherent in both high-accuracy, fine-grained analysis and performance of perception-based activities are manifold, spanning representation, recognition, and task and motion planning.

In this talk, I’ll summarize our work addressing these challenges. I’ll first describe DASZL, our approach to interpretable, attribute-based activity detection. DASZL operates in both pre-trained and zero shot settings and has been applied to a variety of applications ranging from surveillance to surgery. I’ll then describe work on machine learning approaches for systems that use prediction models to support perception-based planning and execution of manipulation tasks. I’ll close with some recent work on “Good Robot,” a method for end-to-end training of a robot manipulation system which leverages architecture search and fine-grained task rewards to achieve state-of-the-art performance in complex, multi-step manipulation tasks. I’ll close with a brief summary of some directions we are exploring, enabled by these technologies.

"Semantic Robot Programming... and Maybe Making the World a Better Place"

May 20, 2021 @ 12:00pm PST

Zoom: https://ucsd.zoom.us/j/91267376688

Speaker: Odest Chadwicke Jenkins, Ph.D.

The visions of interconnected heterogeneous autonomous robots in widespread use are a coming reality that will reshape our world. Similar to "app stores" for modern computing, people at varying levels of technical background will contribute to "robot app stores" as designers and developers. However, current paradigms to program robots beyond simple cases remains inaccessible to all but the most sophisticated of developers and researchers. In order for people to fluently program autonomous robots, a robot must be able to interpret user instructions that accord with that user’s model of the world. The challenge is that many aspects of such a model are difficult or impossible for the robot to sense directly. We posit a critical missing component is the grounding of semantic symbols in a manner that addresses both uncertainty in low-level robot perception and intentionality in high-level reasoning. Such a grounding will enable robots to fluidly work with human collaborators to perform tasks that require extended goal-directed autonomy.

I will present our efforts towards accessible and general methods of robot programming from the demonstrations of human users. Our recent work has focused on Semantic Robot Programming (SRP), a declarative paradigm for robot programming by demonstration that builds on semantic mapping. In contrast to procedural methods for motion imitation in configuration space, SRP is suited to generalize user demonstrations of goal scenes in workspace, such as for manipulation in cluttered environments. SRP extends our efforts to crowdsource robot learning from demonstration at scale through messaging protocols suited to web/cloud robotics. With such scaling of robotics in mind, prospects for cultivating both equal opportunity and technological excellence will be discussed in the context of broadening and strengthening Title IX and Title VI.

Increased autonomy can have many advantages, including increased safety and reliability, improved reaction time and performance, reduced personnel burden with associated cost savings, and the ability to continue operations in communications-degraded or denied environments. Artificial Intelligence for Small Unit Maneuver (AISUM) envisions a way for future expeditionary tactical maneuver elements to team with intelligent adaptive systems. Accordingly, it opens analyses of how such teaming will greatly enhance mission precision, speed, and mass in complex, contested, and congested environments. The ultimate aim in this effort is to reduce risk to missions and our own force, partners, and civilians. AISUM provides competitive advantage in the changing physics of competition space via robotic autonomous systems in dense urban clutter (interior, exterior, subterranean) and dynamic, spectrum-denied areas, with no prior knowledge of the environment in support of human-machine teams for tactical maneuver and swarming tactics.

"Inductive Biases for Robot Learning"

Thursday 22 April @ 12pm PST 

Zoom Link: https://ucsd.zoom.us/j/91267376688

Speaker: Michael Lutter

Abstract: The recent advances in robot learning have been largely fueled by model-free deep reinforcement learning algorithms. These black-box methods utilize large datasets and deep networks to discover good behaviors. The existing knowledge of robotics and control is ignored and only the information contained within the data is leveraged. In this talk we want to take a different approach and evaluate the combination of knowledge and data-driven learning. We show that this combination enables sample-efficient learning for physical robots and that generic knowledge from physics and control can be incorporated in deep network representations. The use of inductive biases for robot learning yields robots that learn dynamic tasks within minutes and robust control policies for under-actuated systems.

Bio: Michael Lutter joined the Institute for Intelligent Autonomous Systems (IAS) at TU Darmstadt in July 2017. Prior to this Michael held a researcher position at the Technical University of Munich (TUM) for bio-inspired learning for robotics. During this time he worked on the Human Brain Project, a European H2020 FET flagship project. In addition to his studies, Michael worked for ThyssenKrupp, Siemens and General Electric and received multiple scholarships for academic excellence and his current research.

"Patient-Specific Continuum Robotic Systems for Surgical Interventions"

Thursday 15 April @ 12pm PST (also CSE290)
Zoom Link: https://ucsd.zoom.us/j/91267376688

Speaker: Jaydev P. Desai
Georgia Institute of Technology

Abstract:
Over the past few decades, robotic systems for surgical interventions have undergone tremendous transformation. The goal of a surgical intervention is to try to do it as minimally invasively as possible, since that significantly reduces post-operative morbidity, reduces recovery time, and also leads to lower healthcare costs. However, minimally invasive surgical interventions for a range of procedures will require a significant change in the healthcare paradigm for both diagnostic and therapeutic interventions. Advances in surgical interventions will benefit from “patient-specific robotic tools” to deliver optimal diagnosis and therapy. Hence, this talk will focus on the development of continuum, flexible, and patient-specific robotic systems for surgical interventions. Since, these robotic systems could operate in an imaging environment, we will also address challenges in image-guided interventions. This talk will present examples from neurosurgery and endovascular interventions to highlight the applicability of patient-specific robotic systems for surgery.

"Visual Representations for Navigation and Object Detection"

Abstract: Advancements in reliable navigation and mapping rest to a large extent on robust, efficient and scalable understanding of the surrounding environment. The success in recent years have been propelled by the use machine learning techniques for capturing geometry and semantics of environment from video and range sensors. I will discuss approaches to object detection, pose recovery, 3D reconstruction and detailed semantic parsing using deep convolutional neural networks (CNNs).
While data-driven deep learning approaches fueled rapid progress in object category recognition by exploiting large amounts of labelled data, extending this learning paradigm to previously unseen objects comes with challenges. I will discuss the role of active self-supervision provided by ego-motion for learning object detectors from unlabelled data. These powerful spatial and semantic representations can then be jointly optimized with policies for elementary navigation tasks. The presented explorations open interesting avenues for control of embodied physical agents and general strategies for design and development of general purpose autonomous systems.

"Safe Real-World Autonomy in Uncertain and Unstructured Environments"

Zoom URL: https://ucsd.zoom.us/j/97197176606

Sylvia Herbert - UCSD

 

In this talk I will present my current and future work towards enabling safe real-world autonomy. My core focus is to enable efficient and safe decision-making in complex autonomous systems, while reasoning about uncertainty in real-world environments, including those involving human interactions. These methods draw from control theory, cognitive science, and reinforcement learning, and are backed by both rigorous theory and physical testing on robotic platforms.

First I will discuss safety for complex systems in simple environments. Traditional methods for generating safety analyses and safe controllers struggle to handle realistic complex models of autonomous systems, and therefore are stuck with simplistic models that are less accurate. I have developed scalable techniques for theoretically sound safety guarantees that can reduce computation by orders of magnitude for high-dimensional systems, resulting in better safety analyses and paving the way for safety in real-world autonomy.

Next I will add in complex environments. Safety analyses depend on pre-defined assumptions that will often be wrong in practice, as real-world systems will inevitably encounter incomplete knowledge of the environment and other agents. Reasoning efficiently and safely in unstructured environments is an area where humans excel compared to current autonomous systems. Inspired by this, I have used models of human decision-making from cognitive science to develop algorithms that allow autonomous systems to navigate quickly and safely, adapt to new information, and reason over the uncertainty inherent in predicting humans and other agents. Combining these techniques brings us closer to the goal of safe real-world autonomy.

"Abstractions in Robot Planning"

https://ucsd.zoom.us/j/97197176606

Neil T. Dantam, Colorado School of Mines

 

Abstract: Complex robot tasks require a combination of abstractions and algorithms: geometric models for motion planning, probabilistic models for perception, discrete models for high-level reasoning. Each abstraction imposes certain requirements, which may not always hold. Robust planning systems must therefore resolve errors in abstraction. We identify the combinatorial and geometric challenges of planning for everyday tasks, develop a hybrid planning algorithm, and implement an extensible planning framework. In recent work, we present an initial approach to relax the completeness assumptions in motion planning.

Bio: Neil T. Dantam is an Assistant Professor of Computer Science at the Colorado School of Mines. His research focuses on robot planning and manipulation, covering task and motion planning, quaternion kinematics, discrete policies, and real-time software design.

He has worked at iRobot Research, MIT Lincoln Laboratory, and Raytheon. Neil received the Georgia Tech President's Fellowship, the Georgia Tech/SAIC paper award, an American Control Conference '12 presentation award, and was a Best Paper and Mike Stilman Award finalist at HUMANOIDS '14.

"Probabilistic Robotics and Autonomous Driving"

 https://ucsd.zoom.us/j/97197176606

Wolfram Burgard, Toyota Research Institute

 

Abstract: For autonomous robots and automated driving, the capability to robustly perceive their environments and execute their actions is the ultimate goal. The key challenge is that no sensors and actuators are perfect, which means that robots and cars need the ability to properly deal with the resulting uncertainty. In this presentation, I will introduce the probabilistic approach to robotics, which provides a rigorous statistical methodology to solve the state estimation problem. I will furthermore discuss how this approach can be extended using state-of-the-art technology from machine learning to bring us closer to the development of truly robust systems able to serve us in our every-day lives. In this context, I will in particular focus on the data advantage that the Toyota Research Institute is planning to leverage in combination with self-/semi-supervised methods for machine learning to speed up the process of developing self-driving cars.

Bio: Wolfram Burgard received the Ph.D. degree in computer science from University of Bonn, Bonn, Germany, in 1991.He is currently VP of Autonomous Driving at Toyota Research Institute and a Professor of computer science with University of Freiburg, Freiburg, Germany, where he heads the Laboratory for Autonomous Intelligent Systems.

"Key Challenges in Agricultural Robotics with Examples of Ground Vehicle Localization in Orchards and Task-Specific Manipulator Design for Fruit Harvesting"

EBU 1 - Qualcomm Conference Room 

Amir Degani - Technion (Israel Institute of Technology) 

 

Dr Amir Degani is an Associate Professor at the Technion - Israel Institute of Technology. Dr Degani is the Director of the Civil, Environmental, and Agricultural Robotics (CEAR) Laboratory researching robotic  legged locomotion and autonomous systems in civil and agriculture applications. His research program includes mechanism analysis, synthesis, control and motion planning and design with emphasis on minimalistic concepts and the study of nonlinear dynamic hybrid systems.

His talk will present the need for robotics in agriculture and focus on examples of solutions for two different problems. The first is the localization of an autonomous ground vehicle in a homogenous orchard environment. The typical localization approaches are not adjusted to the characteristics of the orchard environment, especially the homogeneous scenery. To alleviate these difficulties, Dr Degani and his colleagues use top-view images of the orchard acquired in real-time. The top-view observation of the orchard provides a unique signature of every tree formed by the shape of its canopy. This practically changes the homogeneity premise in orchards and paves the way for addressing the “kidnapped robot problem”.

The second part of the talk will focus on efforts to define and perform task-based optimization for an apple-harvesting robot. Since there is a large variation between trees, instead of performing this laborious optimization on many trees, Dr Degani and his colleagues look for a “lower dimensional” characterization of the trees. Moreover, the shape of the tree (i.e., the environment) has a major influence on the robot’s simplicity. Therefore, Dr Degani and his colleagues strive to find the best training system for a tree to help simplify the robot’s design.

"Efficient memory-usage techniques in deep neural networks via a graph-based approach"

Qualcomm Conference Room (EBU-1)

Salimeh Yasaei Sekeh - University of Maine 

Dr. Salimeh Yasaei Sekeh is the Assistant Professor of Computer Science in the School of Computing and Information Sciences at the University of Maine. Her research focuses on designing and analyzing machine learning algorithms, deep learning techniques, applications of machine learning approaches in real-time problems, data mining, pattern recognition, and network structure learning with applications in biology. This talk introduces two new and efficient deep memory usage techniques based on the geometric dependency criterion. This first technique is called Online Streaming Deep Feature Selection. This technique is based on a novel supervised streaming setting and it measures deep feature relevance while maintaining a minimal deep feature subset with relatively high classification performance and less memory requirement. The second technique is called Geometric Dependency-based Neuron Trimming. This technique is a data-driven pruning method that evaluates the relationship between nodes in consecutive layers. In this approach, a new dependency-based pruning score removes neurons with least importance, and then the network is fine-tuned to retain its predictive power. Both methods are evaluated on several data sets with multiple CNN models and demonstrated to achieve significant memory compression compared to the baselines.

"Human-Machine Teaming at the Robotics Research Center at West Point"
