Boston Dynamics details its redesigned four-fingered humanoid robot hand

Boston Dynamics says its new humanoid hand has four fingers, 13 degrees of freedom, and direct actuation, and it is designed for mass manufacturing.

The company dropped the pinky finger and reduced the gripper size, and built the hand for high-fidelity simulation to enable sim-to-real reinforcement learning.

Alberto Rodriguez, director of robot behavior for Atlas, says the earlier hands could already lift more than 100 lb., so the new design focuses on reliability and tool use.
