AthenaZero uses low-inertia arms for fast throwing, catching and batting

RAI Institute's AthenaZero is a bimanual research robot built for fast movements and compliant contact. Quasi-direct-drive actuators and moving actuator mass closer to the torso reduce the effective mass at the arms, helping the system accelerate and respond to impacts rather than relying on rigid positioning. The researchers report throwing above 30 metres per second and catching and batting above 14 metres per second over a 7.3-metre distance. Robot-to-robot and human-to-robot demonstrations test dynamic manipulation, not a commercial baseball product or a deployed industrial system. Electronics For You covered the work on 12 October. The primary manuscript was submitted on 15 September 2026, and the RAI Institute had described the prototype in April. Its developers also note limits in sustained torque output and high-stiffness tasks. Industrial uses remain potential applications requiring further validation.
