An untethered bipedal robot completed a five-kilometer (3.10-mile) run in just over 53 minutes.

The Cassie robot, engineered by Oregon State University (OSU) researchers and built by OSU spinout company Agility Robotics, is the first bipedal robot to use machine learning to maintain a running gait on outdoor terrain.

The robot taught itself to run using a reinforcement learning algorithm, and it makes subtle adjustments to remain upright while in motion.

OSU's Jonathan Hurst said Cassie's developers "combined expertise from biomechanics and existing robot control approaches with new machine learning tools.”

Hurst added, “In the not-very-distant future, everyone will see and interact with robots in many places in their everyday lives, robots that work alongside us and improve our quality of life.”
