The Robot Threw Faster Than 30 Meters per Second
AthenaZero moved at human timescales by cutting effective endpoint mass to roughly that of a human arm.
Summary
AthenaZero moved at human timescales by cutting effective endpoint mass to roughly that of a human arm.
Dynamic manipulation is constrained by the mass a robot must accelerate at its endpoint. AthenaZero combines quasi-direct-drive actuation with remotely mounted transmissions to keep effective endpoint mass about an order of magnitude below conventional manipulators while retaining torque transparency. The bimanual system threw a ball above 30 meters per second and caught or batted balls moving above 14 meters per second across a 7.3-meter lane. Robot-to-robot and human-to-robot games of catch demonstrate the design's speed; the evidence is a platform paper, not a general guarantee for unstructured environments.
