Charbel Rizk: Low Cost Autonomous Systems – Challenges and Opportunities @ B17 Hackerman Hall
Apr 19 @ 12:00 pm – 1:00 pm

Abstract

The sophistication of Unmanned Aerial Vehicles (UAV), otherwise known as drones, is increasing while their cost is decreasing and is quickly approaching consumer prices. This technology, like most others, adds tremendous value to humanity but also challenges. This dichotomy has motivated our research from the early 90’s to develop more capable platforms and more recently to explore technologies that can mitigate the risks associated with drone proliferation. We will present examples of our work on both sides of this spectrum. One particular area with tremendous potential impact is on the sensor and processing (payload) side. We have been the thought leaders on computational sensors and are on a path to reaching size, weight, and power constraints commensurate or exceeding biological equivalents. This revolution in integrated sensing and computing is likely to enable a new class of autonomous and very capable systems. In particular, we are exploring the interface between biological and engineered systems. Biological creatures are highly efficient, autonomous, and mobile with minimal sensory requirements. Their endurance and mobility remain far unmatched especially as the size decreases and that is the subject of intense research. We believe that solutions that build on the best of both worlds may produce better performance than either on its own and our focus is on the optimal integration of engineered payloads with natural hosts. Another complementary area of our research is small robotics with our recent focus for endoscopic medical procedures. In particular, we are developing a self-propelled aiding endoscope based on biomimetic peristaltic locomotion, and potential solutions may reside in what is becomingly known as soft robotics.

LCSR Seminar: Sonja Glavaski @ Malone G33
May 1 @ 11:00 am – 12:00 pm

Title

Grid of the Future: Controlling the Edge

Abstract

The evolution of the grid faces significant challenges if it is to integrate and accept more energy from renewable generation and other Distributed Energy Resources (DERs). To maintain grid’s reliability and turn intermittent power sources into major contributors to the U.S. energy mix, we have to think about the grid differently and design it to be smarter and more flexible.

 

ARPA-E is interested in disruptive technologies that enable increased integration of DERs by real-time adaptation while maintaining grid reliability and reducing cost for customers with smart technologies. The potential impact is significant, with projected annual energy savings of more than 3 quadrillion BTU and annual CO2 emissions reductions of more than 250 million metric tons.

 

This talk will identify opportunities in developing next generation control technologies and grid operation paradigms that address these challenges and enable secure, stable, and reliable transmission and distribution of electrical power.  Innovative approaches to coordinated management of bulk generation, DERs, flexible loads, and storage assets with multiple roles, and revenue streams will be discussed. Summary of ARPA-E NODES (Network Optimized Distributed Energy Systems) Program funding development of these technologies will be presented.

Abstract

Over the last 15 years Autonomous Underwater Vehicles (AUVs) have migrated finicky experiments to a mature capability providing routine operational support to deep sea scientists. Moreover, the boundaries of science that can be conducted with AUVs are advancing rapidly and in unexpected directions. The AUV Sentry entered the National Deep Submergence Facility (NDSF) in 2010 and has completed more than 420 dives in support of Ocean Science. Sentry operates up to 190 days per year and is a “fly-away” system that can be shipped to a vessel of opportunity anywhere in the world by land, sea, or air freight. Sentry has a unique design emphasizing maneuverability, steep terrain and extreme mission flexibility. It carries a wide range of standard sensors including a Multibeam Echo Sounder, a Sidescan Sonar, a Sub Bottom Profiler, a high resolution color camera and a variety of water chemistry sensors. A substantial number of custom sensors have been added and recently even sampling has been performed. Payload re-configuration between cruises and even between dives is routine and tens of new capabilities are added every year.
Increasingly acoustic communications are being used to interact with AUVs mid-mission for monitoring or mission intervention. However, these capabilities are still new and we have only scratched the surface of what is possible.
This talk will begin with a presentation of the AUV Sentry and typical science missions. It will then discuss the present state of the art in acoustic interaction and will conclude with a look at possible future directions for these technologies.

LCSR Special Seminar: Avik De “Stable hopping and running from compositions of dynamical primitives” @ B17 Hackerman Hall
Jun 28 @ 12:00 pm – 1:00 pm

Abstract

The first dynamic legged robots (developed by Raibert) were controlled using a “three-part” hopping strategy, synthesized by developing controllers in isolation (e.g. vertical hopping controller ignores fore-aft motion). Dynamical systems theory can offer a formal representation of such reductions in terms of attracting invariant submanifolds with restriction dynamics conjugate to a template system, which itself may be a composition of several dynamical primitives. Such notions of reduction have appeared before in the literature (in the form of “anchored templates”, “zero dynamics”, “dynamic motion primitives”, “locomotor subfunctions”), and also in running animals across several orders of magnitude of scale. However, formal synthetic embedding (“anchoring”) of these requires cancellation of coupling terms appearing in the natural dynamics, which requires abundant actuation, sensing fidelity, and parametric certainty.
We introduce a new notion of approximate “averaged” anchoring which allows compositions of simple decoupled controllers (such as Raibert’s) to successfully embody dynamic running and hopping on a quadruped and tailed biped with few parameters and a great deal of empirical robustness. We then describe our new advances: a new analytical tool for formal verification of these compositions (hybrid averaging), which reveals for the first time (a) connections between morphology and composition, and (b) how within-stance time-reversal symmetry helps mitigate coupling interactions. We end with work-in-progress on compositions of feedback-stabilized attractors as robust reference generators for walking without any  feedforward components.

He graduated with a BS/MS in Mechanical Engineering from Johns Hopkins University in 2010, during which he performed an empirical study on how/when human beings inject feedback to stabilize a 1-dimensional paddle juggling task. Bio-inspiration remains a key research interest, and during his PhD, he switched his efforts into modular/compositional control of dynamic locomotion, as well as the design of dynamic locomotor systems. He co-founded “Ghost Robotics” in 2016, commercializing research that led to the creation of a family of power-dense direct-drive legged robots with high actuation bandwidth and proprioceptive sensing capabilities. He has in part created curriculum for two online courses: “Robotics: Mobility”, and “Robotics: Capstone” on coursera.

LCSR Seminar: Chien-Ming Huang ” Designing Intuitive Interactions for Human-Robot Teams” @ B17 Hackerman Hall
Sep 20 @ 12:00 pm – 1:00 pm

Abstract

Robots hold promise in assisting people in a variety of domains including healthcare services, household chores, collaborative manufacturing, and educational learning. In supporting these activities, robots need to engage with humans in cooperative interactions in which they work together toward a common goal in a socially intuitive manner. Such interactions require robots to coordinate actions, predict task intent, direct attention, and convey relevant information to human partners. In this talk, I will present how techniques in human-computer interaction, artificial intelligence, and robotics can be applied in a principled manner to create and study intuitive interactions between humans and robots. I will demonstrate social, cognitive, and task benefits of effective human-robot teams in various application contexts. I will discuss broader impacts of my research, as well as future directions of my research focusing on intuitive computing.

LCSR Seminar: Sarah Bergbreiter “Microsystems-inspired Robotics” @ B17 Hackerman Hall
Oct 4 @ 12:00 pm – 1:00 pm

Abstract

The ability to manufacture micro-scale sensors and actuators has inspired the robotics community for over 30 years. There have been huge success stories; MEMS inertial sensors have enabled an entire market of low-cost, small UAVs. However, the promise of ant-scale robots has largely failed. Ants can move high speeds on surfaces from picnic tables to front lawns, but the few legged microrobots that have walked have done so at slow speeds (< 1 body length/sec) on smooth silicon wafers. In addition, the vision of large numbers of microfabricated sensors interacting directly with the environment has suffered in part due to the brittle materials used in microfabrication. This talk will present our progress in the design of sensors, mechanisms, and actuators that utilize new microfabrication processes to incorporate materials with widely varying moduli and functionality to achieve more robustness, dynamic range, and complexity in smaller packages. Results include skins of soft tactile or strain sensors with high dynamic range, new models of bio-inspired jumping mechanisms, and magnetically actuated legged microrobots from 1 gram down to 1 milligram that provide insights into simple design and control for high speed locomotion in small-scale mobile robots.
