Boston Dynamics 发布 Atlas 人形机器人的新手部，13 自由度、4 指、直接驱动，支持手内重定向、防滑恢复和扣动电钻、角磨机、射钉枪等工具扳机，取代原 7 自由度抓取手。设计上故意去掉小指，传动器可后驱且易于仿真，指尖和手掌有触觉传感，尺寸接近人手以缩小与人手示范数据的差距。

Boston Dynamics unveiled a new hand for Atlas.
13 DOF, 4 fingers, directly actuated. The old 7-DOF hand was built to grasp objects; this one is built to manipulate them, in-hand reorientation, slip recovery, and pulling tool triggers (drills, grinders, nail guns).
No pinky, on purpose. The CTO had the team tape their pinky and ring fingers together for a day, and the verdict was: you don't need it. "The best part is no part."
Built for sim-to-real RL: backdrivable, cleanly simulatable actuators, plus tactile sensing on fingertips and palm. Human-hand sized to shrink the gap to human demo data.
