Boston Dynamics unveils new Atlas hands with four fingers

Boston Dynamics showed off a new pair of hands for its Atlas robot: four fingers instead of five and 13 degrees of freedom, up from seven on the older GR2 gripper. Each joint is driven by a motor tucked inside the finger, while pads on the fingertips and palm detect even the lightest touch.

• New Atlas hand has four fingers and 13 degrees of freedom, up from seven on GR2
• Motors sit inside the fingers, eliminating external wiring
• Thumb has four joints and can meet any other finger
• Atlas already presses triggers on drills, torque drivers and welding torches
