About Cassie

Cassie used spring-like articulated legs and a compact torso-free structure to isolate the problems of dynamic bipedal locomotion. The platform supported walking over uneven ground, recovery from disturbances and increasingly fast outdoor movement, giving research teams access to a durable physical system for testing control and reinforcement-learning methods.

Agility sold Cassie as a research platform from 2017 until 2019 before transitioning production to Digit. Digit added a torso, arms, perception and onboard compute to the locomotion architecture developed through Cassie. The earlier robot is therefore a discontinued research platform and technical predecessor, not part of Agility Robotics’ current commercial product portfolio.
