AthenaZero
AthenaZero is a Robotics & AI Institute research prototype built for dynamic, contact-rich bimanual manipulation. The platform combines a one-degree-of-freedom torso, two 7-DoF arms, and two 6-DoF underactuated hands, with low gear-ratio quasi-direct-drive actuation intended to reduce reflected inertia and make the arms more compliant during contact. RAI has demonstrated the robot throwing a ball at 70 mph, catching balls over a short 7.3 m distance, adapting its batting swing in real time, and juggling barehanded with onboard vision feedback.
