Oregon State University’s (OSU) spinout company Agility Robotics has set a new record with their bipedal Cassie robot 5 kilometers, completing the route in just over 53 minutes. It’s the first bipedal robot to utilize machine learning to control a running gait on outdoor terrain, completely untethered on Oregon State’s campus and on a single battery charge. This robot has knees that bend like an ostrich’s, enabling it to run faster than previous models. Read more for a video and additional information.
Cassie taught itself to run using a deep reinforcement learning algorithm, which allowed it to maintain balance while switching positions or otherwise being in motion. During this record setting run, Cassie’s total time included around 6.5-minutes of resets following two falls. In the future, bipedal robots will be able to assist humans in package delivery as well as in their own homes.

The Dynamic Robotics Laboratory students in the OSU College of Engineering combined expertise from biomechanics and existing robot control approaches with new machine learning tools. This type of holistic approach will enable animal-like levels of performance. It’s incredibly exciting,” said Jonathan Hurst, co-founder of Agility Robotics.
