About

Michael A. Hopkins is a robotics researcher whose work sits at the intersection of humanoid robot design, compliant control, and dynamic locomotion. Best known for his pivotal contributions to Virginia Tech's DARPA Robotics Challenge efforts, Hopkins played a central role in developing both the THOR and ESCHER humanoid platforms — series elastic bipeds engineered to operate in unstructured, real-world environments. His research has advanced the mechanical design of series elastic actuators, embedded joint-space control, and optimization-based whole-body control frameworks, collectively garnering over 170 citations. His 2015 cluster of papers represents a particularly productive period, establishing foundational methodologies for compliant bipedal locomotion that have influenced subsequent humanoid research. The culmination of this work, documented in "Team VALOR's ESCHER," showcased a full-sized force-controlled humanoid capable of navigating disaster-response scenarios. More recently, Hopkins has expanded his scope toward expressive robotic characters, bridging rigorous locomotion control with entertainment applications — including stylized gait design for physically constrained robots. An early competition achievement at RoboCup 2011 further underscores the breadth of his humanoid robotics experience across both research and applied domains.
