Enhancing Bandwidth and Power Density of Series Elastic Actuators using Elastomers and Convective Cooling

Limited output impedance and low power and torque density are common problems today with many series-elastic-actuated (SEA) robots.  In this talk, we will present one solution to these problems, namely, the adoption of new materials and thermal management techniques for SEAs.  We will discuss the benefits and pitfalls of incorporating elastomers into high-performance actuation as well as methods for convlca_paine-1trolling these new devices.

Dr. Paine received his B.S., M.S., and Ph.D. degrees in electrical and computer engineering from University of Texas (UT) at Austin. His Ph.D. studies focused on the development of the UT Series Elastic Actuator, a compact high-performance actuator for robotics.  From 2012-2013 he was a member of the NASA-JSC DARPA Robotics Challenge team where he helped develop high-performance hardware and software for compliant control of the Valkyrie humanoid robot’s legs and arms. From 2014-2015 he was a postdoctoral fellow in the Human Centered Robotics Lab at UT working on forced convective cooling of electric motors and embedded system design.  He currently serves as the Chief Technology Officer of , a start-up in Austin, TX specializing in advanced actuation and robotic systems.
