Boston Dynamics unveils Atlas GR3 robotic hand with 13 degrees of freedom

Boston Dynamics has introduced the GR3 hand for its Atlas robot, featuring 13 degrees of freedom versus 7 on the GR2 and dropping the pinky finger for durability. Proprioception and sensors enable real-time grip adjustments, with training done in simulation.

• 13 degrees of freedom, up from 7 on the GR2
• Pinky finger omitted to simplify and strengthen the design
• Sensors and proprioception adjust grip in real time
• Trained in simulation using reinforcement learning
