01:46
UC Berkeley AUTOLAB http://bit.ly/AUTOLAB Dex-Net 2.0: Deep Learning to Plan Robust Grasps with Synthetic Point Clouds and Analytic Grasp Metrics. Jeffrey Mahler, Jacky Liang, Sherdil Niyaz, Michael Laskey, Richard Doan, Xinyu Liu, Juan Aparicio Ojea, Ken Goldberg UC Berkeley Contact: Ken Goldberg, [email protected] Jeff Mahler, [email protected] Paper Draft: https://arxiv.org/abs/1703.09312 To Appear: Robotics: Science and Systems (RSS) Conference, MIT, July 2017 To reduce data collection time for deep learning of robust robotic grasp plans, we explore training from a synthetic dataset of 6.7 million point clouds, grasps, and robust analytic grasp metrics generated from thousands of 3D models from Dex-Net 1.0 in randomized poses on a table. We use the resulting dataset, Dex-Net 2.0, to train a Grasp Quality Convolutional Neural Network (GQ-CNN) model that rapidly classifies grasps as robust from depth images and the position, angle, and height of the gripper above a table. Experiments with over 1,000 trials on an ABB YuMi comparing grasp planning methods on singulated objects suggest that a GQ-CNN trained with only synthetic data from Dex-Net 2.0 can be used to plan grasps in 0.8s with a success rate of 93% on eight known objects with adversarial geometry and is 3x faster than registering point clouds to a precomputed dataset of objects and indexing grasps. The GQ-CNN is also the highest performing method on a dataset of ten novel household objects, achieving 99% precision on test objects.

Speaker/Performer: Mario Paniccia, Director of Photonics Technology Lab, Intel Sponsor: CITRIS (Ctr for Information Technology Research in the Interest of Society), UC Berkeley (Headquarters), Research Exchange seminar Abstract: The silicon chip has been the mainstay of the electronics industry for the last 40 years and has revolutionized the way the world operates. Today a silicon chip the size of a fingernail contains over one billion transistors and has the computing power that only a decade ago would take up an entire room of servers. Recently silicon photonics has attracted a great deal of attention since it offers an opportunity for low cost opto-electronic solutions for applications ranging from telecommunications down to chip-to-chip interconnects as well as possible applications in new emerging areas such as optical sensing and or bio-medical applications. Recent advances and research breakthroughs in silicon photonic device performance over the last few years have shown that silicon can be considered as a material onto which one can build future optical devices. While significant efforts are needed to improve device performance and to "commercialize" these technologies, progress is moving at a rapid rate. If successful, silicon may similarly come to impact optical communications as it has impacted the electronics industry.

Professor Miguel Altieri - Agroecology and Climate Change
 
15:48
Miguel Altieri, PhD Miguel Altieri is a Professor at Berkeley's College of Natural Resources. His laboratory is involved in several field projects in California where they are testing ideas of landscape ecology applied to agriculture such as the use of biological corridrs in pest management. The idea is to explore whether corridors can break the nature of monocultures by serving as a conduit for the dispersion of natural enemies within the field thus enhancing thier impact on pest population. The effects of summer cover crops on insect pest populations and associated natural enemies is also being examined in vineyards. Of special interest is to determine whether timing mowing cover crops in alternate rows can force movement of beneficials to adjacent vines to exert pest suppression. His group is also engaged in collaborative work with a number of universities, NGOs and research centers in Africa, Asia and Latin America.

Vibration Energy Harvesting for Wireless Sensor Networks
 
45:07
Vibration Energy Harvesting for Wireless Sensor Networks This is an i4Energy Seminar Speaker: Lindsay Miller, UC Berkeley Sponsors: CITRIS (Ctr for Info Technology Research in the Interest of Society), i4Energy Center Wireless sensor networks have huge potential to improve efficiency and quality of manufacturing operations, enable smart grid applications, and enable demand response/smart buildings, among other exciting applications. Ubiquitous sensor networks would allow two-way communication, real-time remote monitoring, and rapid response to changing conditions. Consider the difference between landline telephones and smart phones to imagine how wireless sensing networks might transform infrastructure, energy, and manufacturing. However, current wireless sensor nodes are expensive to maintain as batteries die and need to be replaced, and the nodes are often very difficult to install. Energy harvesting has the potential to resolve these issues and enable a stick-on, set it and forget it type of node. This talk will highlight the different types of energy harvesting research going on in our group, giving a brief overview of how each technology works and when it might be used. I will then focus in on piezoelectric vibration energy harvesting, which is the subject of my research. I will discuss experimental results of a MEMS harvester tested on machinery, optimization of the harvester, and integration of the energy harvester with energy storage. Finally, I will present a novel resonator design that is able to passively self-tune its frequency to match the input vibration.

Printed Electronic Systems: the Confluence of Printing and Semiconductors
 
46:44
Speaker/Performer: Vivek Subramanian, Professor, UC Berkeley Sponsor: CITRIS (Ctr for Information Technology Research in the Interest of Society), UC Berkeley (Headquarters), i4Energy seminar Abstract: In recent years, there has been significant interest in the applications of printed electronics for the realization of flexible displays, fully-printed RFID tags and embedded sensors. Printing of active circuitry is expected to enable a dramatic reduction in the overall cost of these systems, allowing for integration of electronic barcodes and product quality detection systems into consumer goods, as well as ushering in an era of low cost flexible displays and content delivery appliances. Printing techniques that have been considered range from high-speed commercial gravure printing through ultra-scaled inkjet printing. While many of the printing techniques under consideration have evolved from techniques already widely deployed in graphic arts applications, the requirements for printed electronics are in many ways dramatically different from those that exist for conventional graphic arts. In this talk, I will review the tremendous progress that has occurred in printed electronics over the last decade, and will discuss the challenges that remain. I will discuss the challenges associated with utilizing printing to realize printed semiconductor-based circuits. Additionally, I will overview the state of the art in printed electronic materials. I will review our work on developing materials, processes, devices, and circuit architectures for all-printed electronic systems including RFID tags, displays, and sensing systems.

Chris Somerville [Director of the EBI, UC Berkeley] Abstract: The earth receives approximately 4000 times as much energy from the sun each year as the total projected human energy use in 2050. Because plants can be deployed on a large scale to capture and store solar energy, I am interested in exploring the degree to which it may become possible to use photosynthesis for sustainable production of renewable carbon-neutral energy. In considering this possibility, the Secretary of Energy of the US has called for the replacement of 30% of the liquid fuels used in the US with biofuels by 2030. I will outline some of the technical issues that must be addressed in order to understand if it is possible to reach this and related goals. I will also discuss some of the areas in which I envision significant technical advances may enable evolution of the biofuels industry. Biography: Chris Somerville is the Director of the new Energy Biosciences Institute at UC Berkeley,University of Illinois and Lawrence Berkeley National Laboratory and a professor of Plant and Microbial Biology at UC Berkeley. He has published more than 200 scientific papers and patents in plant and microbial genetics, genomics, biochemistry, and biotechnology.His current research is focused on the characterization of proteins, such as cellulose synthase, implicated in plant cell wall synthesis and modification. Somerville has served as a member of the scientific advisory boards of numerous academic institutions, corporations, and private foundations in Europe and North America. He is a member of the US National Academy of Sciences, The Royal Society of London and the Royal Society of Canada and has received numerous scientific awards.

Earths Many Voices a Unified Theory for Pre-Earthquake Signals
 
01:21:43
Earths Many Voices a Unified Theory for Pre-Earthquake Signals Earths Many Voices a Unified Theory for Pre-Earthquake Signals CITRIS Distinguished Speaker: Friedemann Freund from NASA Friedemann T. Freund NASA Ames Research Center, Earth Science Division, Moffett Field, CA 94035, California Abstract: In this talk, I will discuss the solid-state physics of rocks and earthquake precursors. Earthquake precursor phenomena have been known for some time. They are caused by stresses that build up in crustal rocks. As we have found in the laboratory, these stresses more precisely, differential stresses and strains activate mobile positive charge carriers (defect electrons in the oxygen anion sublattice sublattice: O in a matrix of O2). These positive holes (or pholes for short) flow from the generation region into the surrounding rock. They effectively turn a rock into a giant battery. Under specific conditions, which cause the battery circuit to close, large phole currents can flow. Such currents lead to a variety of phenomena: (i) magnetic field variations and low to ultra-low frequency EM emissions, (ii) ionospheric perturbations over the epicentral region, (iii) air ionization at the ground-air interface and corona discharges with light and radio noise, and (iv) the emission of narrow-band infrared (IR) photons around 10 µm. These excess IR photons are the cause of the so-called thermal IR (TIR) anomaly. Often appearing days before major earth¬quakes, TIR anomalies have been seen from space by NASAs MODIS on TERRA and AQUA, by NOAAs AVHRR and GEOS, by Europes METEOSAT satellites. These various pre-earthquake signals can be used to design an earthquake early warning monitoring system, combining space assets and ground networks. Biography: Friedemann T. Freund is with the NASA Ames Research Center, Earth Science Division, Moffett Field, CA 94035-1000. He is Adjunct Professor, Department of Physics, San Jose State University, San Jose, and Principal Investigator at the Carl Sagan Center, SETI Institute, Mountain View, CA. Dr. Freund came to NASA Ames in 1985 after a 20-year career as professor in Germany at the universities of Göttingen and Cologne. His field of interest started with defects in crystals. This led him to questions related to the origin of Life and, as a spin-off, to the physics of pre-earthquake signals.

Nokia Distinguished Lecture: Jerrold Marsden on Discrete Mechanics and Optimal Control Engineering and Control & Dynamical Systems California Institute of Technology Abstract: We and Nature try to optimize things all the time; find the shortest route to the grocery store, find the most efficient way to throw a discus, cats turning themselves over efficiently, etc. Optimal control is about finding control forces to perform optimal ways of carrying out a task. Many such systems are mechanical and special techniques for computing optimal controls in mechanics will be presented. These techniques are based on recent progress in discrete mechanics. The techniques will be illustrated by systems such as falling cats, reorienting a network of satellites, optimal space mission design, systems with constraints (such as a satellite with momentum wheels), helicopter dynamics, and efficient 2D and 3D robotic walkers. Bio: Jerrold Marsden is a professor of Control and Dynamical Systems at Caltech. He has done extensive research in the area of geometric mechanics, with applications to rigid body systems, fluid mechanics, elasticity theory, plasma physics, as well as to general field theory. His work in dynamical systems and control theory emphasizes how it relates to mechanical systems and systems with symmetry. He is one of the original founders in the early 1970's of reduction theory for mechanical systems with symmetry, which remains an active and much studied area of research today. He has won a number of awards for his research.

Open Innovation Speaker - Henry Chesbrough "Industry-University Research Relationships: The Promise, the Tensions, and Why Weve Got to Get This Right" Industry is playing a growing role as a funding source for discovery-oriented research conducted at universities in the US. This growing role offsets to some degree the decline in federal and state support for universities over the past 30 years. But it also raises important questions about the nature of the American public university in the 21st century. Does growing industry funding compromise the academic quality, integrity and freedom of the research university? Can universities remain open institutions in a world where industry funding plays an increasingly important role? And how are universities addressing these issues? This talk will consider these questions, and address them through a recent case study of the BP-UC Berkeley-UC Illinois Energy Biosciences Institute.

Learning Ambidextrous Robot Grasping Policies - Dex-Net 4.0
 
01:05
Universal picking (UP), or reliable robot grasping of a diverse range of novel objects from heaps, is a grand challenge for e-commerce order fulfillment, manufacturing, inspection, and home service robots. Optimizing the rate, reliability, and range of UP is difficult due to inherent uncertainty in sensing, control, and contact physics. This paper explores “ambidextrous” robot grasping, where two or more heterogeneous grippers are used. We present Dexterity Network (Dex-Net) 4.0, a substantial extension to previous versions of Dex-Net that learns policies for a given set of grippers by training on synthetic datasets using domain randomization with analytic models of physics and geometry. We train policies for a parallel-jaw and a vacuum-based suction cup gripper on 5 million synthetic depth images, grasps, and rewards generated from heaps of three-dimensional objects. On a physical robot with two grippers, the Dex-Net 4.0 policy consistently clears bins of up to 25 novel objects with reliability greater than 95% at a rate of more than 300 mean picks per hour. https://berkeleyautomation.github.io/dex-net/ Video Produced by: Adriel Olmos

IMRI & Positron Emission Tomography: A New Tool for Biomedical Imaging?
 
56:51
Simon Cherry [Professor of Bioengineering, UC Davis] Abstract: Biomedical imaging technologies have revolutionized medicine over the past century and have become indispensable tools in the diagnosis and management of a wide range of diseases, as well as in basic and preclinical research in animal models. Each imaging modality has its own characteristic strengths and weaknesses, and for this reason, there has been a growing trend towards hybrid imaging devices that can integrate the advantages of two different imaging technologies into a single instrument. This presentation will trace the development of hybrid magnetic resonance imaging (MRI) and positron emission tomography (PET) scanners, a new technology that promises to deliver unique imaging capabilities into the biomedical research field, and ultimately into clinical diagnostics. The challenges in integrating these two imaging techniques will be discussed, and early imaging data from prototype systems presented.

Global Warming -- The Current Status: The Science, the Scandal, the Prospects for a Treaty
 
52:15
Global Warming -- The Current Status: The Science, the Scandal, the Prospects for a Treaty Speaker/Performer: Richard Muller, Professor, Dept. of Physics, UC Berkeley Abstract: Recent events in the field of climate change have confused both the public and many "experts." I will try to elucidate what has been happening. Two out of three climate groups show no global warming for the past 13 years. What does that mean? Why does the third group (led by Jim Hansen) disagree? Why was there no treaty at Copenhagen? (It wasn't political, but technical!) Why do we hear so little about the Copenhagen follow-up meeting, this December in Cancun? What really happened in the Climategate scandal? How serious are the mistakes that embarrassed the IPCC (e.g. their claim that the Himalayas might melt in a few decades, subsequently retracted)? How reliable are the predictions of future global warming? (Pretty reliable, in my opinion.) I will attempt to give a non-partisan analysis. ------ Richard A. Muller began his career as a graduate student under Nobel laureate Luis Alvarez doing particle physics experiments and working with bubble chambers. His work has included attempting to understand the ice ages, dynamics at the core-mantle boundary, patterns of extinction and biodiversity through time, and the processes associated with impact cratering. "His "Physics for Future Presidents" series of lectures, in which Muller teaches a synopsis of modern qualitative (i.e. without resorting to complicated math) physics, has been published in book form.

Artificial Intelligence and the Future of Games as an Expres
 
01:00:01
Artificial Intelligence and the Future of Games as an Expressive Medium Michael Mateas [Professor of Computer Science, UC Santa Cruz] Abstract: Artificial intelligence methods open up new possibilities in game design, enabling the creation of believable characters with rich personalities and emotions, interactive story systems that incorporate player interaction into the construction of dynamic plots, and authoring systems that assist human designers in creating games. Games are fast becoming a major medium of the 21st century, being used for everything from education, to editorial news commentary, to expressing public policy and political opinions. Game AI research can radically expand the expressiveness of games, supporting them in becoming a mainstream medium for societal discourse. These ideas will be illustrated by looking at two projects: the interactive drama Façade (released July 2005, downloadable from www.interactivestory.net) and current work on automated game design support. Bio: Michael Mateas' research in AI-based art and entertainment combines science, engineering and design into an integrated practice that pushes the boundaries of the conceivable and possible in games and other interactive art forms. He is currently a faculty member in the Computer Science department at UC Santa Cruz, where he helped launch UCSC's game design degree, the first such degree offered in the UC system. Prior to Santa Cruz, Michael was a faculty member at The Georgia Institute of Technology, where he held a joint appointment in the College of Computing and the School of Literature, Communication and Culture, and founded the Experimental Game Lab. With Andrew Stern, Michael released Façade, the world's first AI-based interactive drama in July 2005. Façade has received numerous awards, including top honors at the Slamdance independent game festival (co-located with the Sundance film festival). Michael's current research interests include game AI, particularly character and story AI, ambient intelligence supporting non-task-based social experiences, and dynamic game generation. Michael has presented papers and exhibited artwork internationally including SIGGRAPH, the New York Digital Salon, AAAI, CHI, the Game Developers Conference, ISEA, AIIDE, the Carnegie Museum, and Te PaPa, the national museum of New Zealand. Michael received his Ph.D. in Computer Science from Carnegie Mellon University. Prior to CMU, Michael worked at Intel Laboratories, where he co-founded the ethnographic research group that eventually became People and Practices Research, and Tektronix Laboratories, where he developed qualitative design methodologies and built advanced interface prototypes.

Future of Distributed Energy Resources
 
49:33
Ryan Hanley is the VP of Grid Engineering Solutions at SolarCity. Distributed energy resources (DER), and the customers who deploy them, are no longer new to the energy space. Consumer-sited DERs such as rooftop solar, stationary batteries, electric vehicles, smart inverters, and dynamic loads are showing up in homes and business across the country, even making appearances at booths within Consumer Electronics Shows. In fact, Navigant research forecasts that DERs will more than double in penetration in the next 7 years in the United States, growing three times faster than new central station energy generation. While DERs no longer sit on the sidelines with consumers, the industry still has progress to make before fully unlocking the technical potential of these assets to improve grid design, operations, affordability, and consumer satisfaction. In this CITRIS seminar, Ryan Hanley will highlight the potential that distributed energy resources hold for driving innovation in grid design, planning, and operations. Ryan will speak to SolarCity’s new cutting edge research, product development, and field deployments and while identifying opportunities for energy industry stakeholders to tackle some of the obstacles that inhibit the full utilization of DERs.

Computational Microscopy
 
48:04
Computational imaging involves the joint design of imaging system hardware and software, optimizing across the entire pipeline from acquisition to reconstruction. This talk will describe new methods for computational microscopy with coded illumination, based on a simple and inexpensive hardware modification of a commercial microscope. Traditionally, one must trade field-of-view for resolution; with our methods we can have both, resulting in Gigapixel-scale images with resolution beyond the diffraction limit of the system. Our reconstruction algorithms are based on large-scale nonlinear non-convex optimization procedures for phase retrieval. Laura Waller leads the Computational Imaging Lab, which develops new methods for optical imaging, with optics and computational algorithms designed jointly. She holds the Ted Van Duzer Endowed Professorship and is a Senior Fellow at the Berkeley Institute of Data Science (BIDS), with affiliations in Bioengineering and Applied Sciences & Technology. Laura was a Postdoctoral Researcher and Lecturer of Physics at Princeton University from 2010-2012 and received BS, MEng and PhD degrees from MIT in 2014, 2015 and 2010, respectively. She is a Moore Foundation Data-Driven Investigator, Bakar fellow, Distinguished Graduate Student Mentoring awardee, NSF CAREER awardee and Packard Fellow.
