Boston Dynamics Unveils Advanced Three-Fingered Gripper for Atlas Humanoid Robot

Boston Dynamics Advances Robotic Hand Technology

Boston Dynamics, the Massachusetts-based robotics company, has unveiled a significant update to its Atlas humanoid robot, focusing on one of the most challenging aspects of robotics: the hands. This development comes over 12 years after Atlas was first introduced, showcasing the company's continuous progress in both mobility and AI capabilities 1

The New Three-Fingered Gripper

Instead of attempting to fully replicate a human hand, Boston Dynamics has opted for a more practical approach by developing a rugged and reliable gripper. The new design features three fingers and an opposing thumb, striking a balance between complexity and functionality 1

Karl Price, a mechanical engineer for Atlas, demonstrated the second-generation device, which boasts impressive specifications:

• Seven degrees of freedom
• Seven different actuators (two for each finger and one for the articulated thumb joint)
• Tactile sensing on the fingertips
• Cameras integrated into the palm

Enhanced Capabilities and Applications

The addition of the articulated thumb has significantly expanded Atlas's grasping abilities. Alberto Rodriguez, director of robot behavior for Atlas, explained, "That really expands the type of grasps that it allows us to do. Over the last year or so, we've realized that we can grasp almost anything that we throw at it" 2

This advancement in gripper technology enables Atlas to perform a wide range of tasks more efficiently, including:

1. Sorting
2. Picking and packing
3. Handling heavy objects
4. Manipulating delicate items with precision
