"Reinventing Human-Robot Interaction for Companion Robots"
Thursday 21 October @ 11AM PST (Virtual Seminar)
Join URL: https://ucsd.zoom.us/j/94406976474
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.
In this presentation, Paolo Pirjanian will discuss Embodied’s solution and our first product, Moxie, targeting children as a solution to promote social, emotional and cognitive skills.
Paolo Pirjanian received his M.Sc and Ph.D. in CSE from Aalborg University. He was a Post-Doc at USC and then at JPL are a research scientist. From JPL he came to Evolution Robotics and was the CTO and Later the CEO before it was acquired by iRobot. He has served as at the CTO of iRobot and is the founder and CEO of Embodied. He is a NASA scientist turned robotics entrepreneur who has helped create technologies for many products ranging from the Sony AIBO to the iRobot Roomba and most recently Moxie.
"Enabling Grounded Language Communication for Human-Robot Teaming "

Join URL: https://ucsd.zoom.us/j/94406976474
Speaker: Professor Thomas Howard
The ability for robots to effectively understand natural language instructions and convey information about their observations and interactions with the physical world is highly dependent on the sophistication and fidelity of the robot’s representations of language, environment, and actions. As we progress towards more intelligent systems that perform a wider range of tasks in a greater variety of domains, we need models that can adapt their representations of language and environment to achieve the real-time performance necessitated by the cadence of human-robot interaction within the computational resource constraints of the platform. In this talk I will review my laboratory’s research on algorithms and models for robot planning, mapping, control, and interaction with a specific focus on language-guided adaptive perception and bi-directional communication with deliberative interactive estimation.

"Beyond the Label: Robots that Reason about Object Semantics"
Thursday 7th October @ 11AM PST
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.
Sonia Chernova is an Associate Professor in the College of Computing at Georgia Tech. She directs the Robot Autonomy and Interactive Learning lab, where her research focuses on the development of intelligent and interactive autonomous systems.

"Learning Where to Trust Unreliable Models for Deformable Object Manipulation"
Thursday, Sept. 30 @ 11AM PST
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
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
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.

"Autonomous Mobile Robot Challenges and Opportunities in Domain and Mission Complex Environments"
Thursday, 6 May @ 12pm PST (in person CSE 1202)
Speaker: Bruce Morris
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.

"Patient-Specific Continuum Robotic Systems for Surgical Interventions"

Zoom Link: https://ucsd.zoom.us/j/91267376688
Speaker: Jaydev P. Desai
Georgia Institute of Technology
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.

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.
Sylvia Herbert is an Assistant Professor in Mechanical and Aerospace Engineering at the University of California San Diego. Prior to joining UCSD, she received her PhD in Electrical Engineering from UC Berkeley, where she studied with Professor Claire Tomlin on safe and efficient control of autonomous systems.

"Abstractions in Robot Planning"
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.

"Probabilistic Robotics and Autonomous Driving"
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.

"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"
Qualcomm Conference Room (EBU-1)
Misha Novitzky - West Point
Dr. Misha Novitzky is the Assistant Professor of the Robotics Research Center in the United States Military Academy at West Point. His work focuses on human-machine teaming for cooperative tasks in stressful and unconstrained environments. This talk will provide a brief overview of the various projects being conducted by the Robotics Research Center at the United States Military Academy, located in West Point, New York. In particular, the talk will focus on human-machine teaming. Most human-robot interaction or teaming research is performed in structured and sterile environments. It is our goal to take human-machine teaming outside into unstructured and stressful environments. As part of this effort, we will describe Project Aquaticus in which humans and robots were embedded in the marine environment and played games of capture the flag against similarly situated teams, and present results of our pilot studies. While Project Aquaticus was previously performed at the Massachusetts Institute of Technology, we will describe why the Robotics Research Center at West Point is an exceptional location to perform future human-machine teaming research.
