Boston Dynamics details new four-finger dexterous hand design for Atlas

Boston Dynamics introduced its redesigned four-finger dexterous hand for the humanoid robot Atlas, featuring 13 degrees of freedom, direct drive, the ability to handle objects over 100 pounds, and a design intended for mass production. Director Alberto Rodriguez said the hand drops the pinky finger, uses 13 fully enclosed identical actuators with no fragile cables spanning joints, and is designed for high-fidelity simulation and sim-to-real reinforcement learning; the team has tested industrial tasks such as power tool use, cable handling, and screw finding, but has not yet deployed it across the entire robot fleet.
