Steve Kaehler facilitated a webinar presentation about autonomous vehicle technology presented and recorded on Oct 11, 2018 titled The Engineering Challenges of Autonomous Driving
Abstract: The move to autonomous driving is unlike anything in the 130-year history of the automobile. Autonomy will eventually be incorporated into hundreds of millions of vehicles; and when it arrives, it will need to work flawlessly.
In this webinar, Design News will examine the challenges facing the automotive community, from the OEMs to Tier One and Tier Two suppliers. We’ll look at the sensors, processors and software. And we’ll examine the validation and verification techniques that will allow engineers to better comprehend the breadth of potential challenges and enable the vehicles themselves to make the right decisions. From cameras and computers to algorithms and simulation systems, here’s a look at technology that will take the automotive industry into the era of autonomous driving.
Professor John Swensen of Washington State University in Pullman presented "Soft Robotics: Robots that interact with and act like soft tissue" via a Google Hangout.
Presentation Abstract: Soft robotics and compliant robotic mechanisms have achieved great popularity in the past decade within the academic community. This soft robotics approach is in stark contrast to the traditional paradigm of large, heavy, rapidly-moving robotics in isolated environments. The soft-robotic approach has shown a lot of promise because their compliant nature lends itself well to safety concerns in co-robotics environments and exhibits adaptability and robustness to uncertainty, such as in robotic grasping. However, this same intrinsic compliance in soft robotics is also its biggest pitfall — in many scenarios it is unable to exert necessary forces and control manipulator shape under external loading. This talk will present some of the methods Dr. Swensen’s lab has taken to create soft robotic materials that can switch between acting like traditional rigid robotics and modern soft robotics. Additionally, he will talk about some of his recent work on the interaction between soft robots (like medical needles and catheters) and the soft tissues in which they operate. One particularly promising application is in waterjet-directed steerable needles.
Steve Kaehler facilitated a discussion about robots taking our jobs. Check out the SRS Weblog for more commentary on this topic. Here are the slides from the discussion.
Jason Russell, PNW Territory Account Manager for Stratasy/GoEngineer talked about the latest 3D Printer Technologies including printing metal. His company worked with the builders of "Disk O' Inferno", a cool combat robot built completely out of 3D printed parts. They have helped a number of teams around the West Coast with material, applications, and additive processes in order to stream line their custom manufacturing processes. Due to the size of his presentation, only a link is provided this time.

October 21, 2017 - How to Build Robots and How NOT to Build them
Tom Carroll presented on the practical mechanical aspects of building robots and covered how NOT to build robots. His experience building robots has taught him a lot about what's possible as well as what's practical. This included building robots for several movies including "Revenge of the Nerds". He discussed drive systems, using gears, arms, treads, and converting his garage into a robot workshop. Tom's bio: Tom Carroll is a retired aerospace robotics engineer, having worked for Rockwell on numerous space and satellite programs from Apollo, ground instrumentation, MinuteMan systems, metrology, to operating an antenna range testing GPS satellite's antennas. He then got into robotics after his chief engineer read a cover story article that Tom wrote for the April 1984 issue of Popular Mechanics on the "5 Best Home-Built Robots". He spent a lot of time at NASA Johnson Space Center and at Langley Research Center in Hampton, VA working on Rockwell's bid for space station robotics. Tom was one of the founders of the Southern California Robotics Society in the late 70's, now called Robotics Society of Southern California--the second robotics group in the US after the one in Albuquerque, NM. The next one was the Homebrew Robotics Society in San Francisco. Time was somewhat short so he had to zip through his presentation but here are his slides (PDF, 8.8MB).

The last years have seen dramatic improvements in robotic capabilities to model, detect, and track non-rigid objects such as human bodies, hands, and their own manipulators. These recent developments can serve as the basis for providing robots with an unprecedented understanding of their environment and the people therein.

February 17, 2007 - "WiMo Robot" and Microsoft Robotics Studio
Brian Cross introduced us to WiMo (pronounced "Weemo"), a Windows Mobile Robot. The name comes from the "Wi" from "Windows" and "Mo" from "Mobile." He explained its origin and evolution as Windows Mobile Robot he developed with no prior robot-building experience. The entire system consisted of a Windows laptop with Bluetooth (for code development in MSRS), Windows-Mobile-capable cell phone with Bluetooth (to receive and execute the code), and an OOPIC with a Bluetooth module on the robot to execute the control functions.
The laptop sent code developed and compiled in Microsoft Robotics Studio (MSRS) to the cell phone for storage and execution. The robot is actually just the cell phone and an OOPIC coupled wirelessly via Bluetooth. He explained the basic physical configuration of each component and how they are connected and talked about some things he hopes to do with WiMo in the future.
His demonstrations included: driving the robot from the laptop keyboard, making the robot speak text typed into the laptop, verbally commanding
the robot to "dance," showing the wireless connectivity by physically separating the laptop, cell phone, and robot while still operating it,
retrieving real-time images from the cell phone's camera to the laptop screen, and -- in less than 5 minutes -- creating and executing code to
control the robot with a proportional USB joystick plugged into the laptop. Here is a copy of the WiMo presentation (PDF, 800KB).

April 15, 2006
Karl Böhringer, Associate Professor in UW's Microelectromechanical Systems
(MEMS) department, presented "Micro Manipulation and Micro Robots: Algorithms, Devices, and Applications."
- Sensor solutions for autonomous vehicles
- Software solutions for autonomous vehicles
- Computing solutions for autonomous vehicles
- Verification and validation challenges facing autonomous vehicle engineers
- Speakers: Phil Magney, Founder & Principal, VSI Labs / Matthew Linder, AV Solutions Engineer, VSI Labs / Chris Posch, Director of Engineering – Automotive, FLIR Systems
- Registration Link
Microelectromechanical systems (MEMS) are tiny machines built with techniques derived from the microelectronics industry. Very large numbers of MEMS can be conveniently fabricated in parallel. However, the control and assembly of such massively parallel microsystems gives rise to numerous challenges in modeling, algorithms, as well as in physical implementation.
In this presentation explored parallel micro manipulation and micro assembly by investigating a cilia-like micro conveyor, a precision
docking system for future "pico-satellites", a walking microchip, and selfassembling micro devices.
Karl Böhringer is an associate professor in Electrical Engineering with adjunct appointments in Computer Science & Engineering and in
Mechanical Engineering at the University of Washington, Seattle. He received both his M.S. and Ph.D. degrees in Computer Science from Cornell University and his Diplom-Informatiker degree from the University of Karlsruhe, Germany. He was a visiting scholar at the Stanford Robotics Lab and Transducer Lab and a postdoctoral researcher at the University of California, Berkeley, before joining the faculty at the University of Washington.
His current interests include micromanipulation and microassembly, as well as biomedical implants and bioMEMS for single-cell genomics and
proteomics. His Ph.D. thesis was nominated for the ACM doctoral dissertation award. He received an NSF postdoctoral associateship in 1997, an NSF CAREER award in 1999, and was an NSF New Century Scholar in 2000. His work was featured among the Top 100 Science Stories in Discover Magazine's 2002 "Year in Science." In 2004, he received the IEEE Robotics and Automation Society Academic Early Career Award and a sabbatical fellowship from the Japan Society for the Promotion of Science (JSPS).
