Did you know?
Cassie is named after the Cassowary, a flightless bird with a similar leg shape.
Founded in 2015, Agility Robotics develops highly capable bipedal robots for applications that include logistics, telepresence, automated inspection, entertainment, and research. The company's goal is to build legged machines that can go anywhere a person can go. Its first robot, released in 2016, is a bipedal platform called Cassie, a dynamic walking robot that could traverse rough terrain and step over obstacles. It later learned to climb stairs. Unveiled in 2019, Digit is Agility's second robot. Its legs are similar to Cassie's, but Digit is equipped with a torso full of sensors as well as a pair of arms, used for balance, mobility, and manipulation.
Strong and durable, able to handle experiments outdoors without a safety tether. Extremely energy efficient, runs for many hours on a single battery charge.
