Walk the Robot – Preliminary Outdoor Walking with Underactuated Bipedal Robot MARLO

This is MARLO, part of University of Michigan and the successor of Rabbit and MABEL.

Testing done on Saturday November 23, 2013 at 8 AM in front of the EECS Building on the University of Michigan North Campus. The temperature was -2 C (about 29 F). MARLO is an underactuated 3D bipedal robot with passive prosthetic feet. Its feedback control is designed using virtual constraints. In previous experiments, MARLO was attached to a boom. but with improved control, the robot can now walk without any external support. A mobile gantry supports a safety cable to catch the robot when it falls, avoiding expensive and time-consuming repairs. The robot is one of 3 ATRIAS-series robots designed and built by Jonathan Hurst at Oregon State University. The other two copies are at CMU [with H. Geyer] and Oregon State.
