Check out this video of the FastRunner being developed by CSAIL Principal Investigator Russ Tedrake in collaboration with researchers at the Florida Institute of Human and Machine Cognition. Sporting legs fashioned by studying the movements of ostrich legs, the test leg for Fast Runner can currently run at 27 miles per hour. FastRunner should eventually be able to run up to 30-50 miles an hour, according to Tedrake.
