Boston Dynamics’ Atlas robotic can flip, run and carry heavy objects with human-like ease. However the actual magic occurs in part of the robotic that’s typically missed: the grippers. Atlas’ mechanical fingers, stuffed with intelligent engineering, can deal with every little thing from espresso cups to automotive components.
Earlier grippers, for the hydraulic Atlas, prioritized mobility over manipulation. When Boston Dynamics switched to an electrical Atlas, the group noticed a possibility to rethink the gripper. They wished one thing that would do extra than simply seize and maintain, one thing that could possibly be a human hand whereas withstanding the trials of a humanoid robotic. The outcome was the GR line of grippers, and the primary one, GR1, was a easy answer, simply sufficient to carry objects. The GR2 goes additional, with 7 levels of freedom, contact sensors and a palm mounted digital camera, it’s a manipulation powerhouse.

The gripper has 3 fingers, 2 regular and 1 opposable thumb, every with its personal actuator which is a small motor that controls motion. The thumb is a key function; it swivels and spins, permitting Atlas to change between delicate pinch grips and sturdy energy grips. This thumb makes the gripper extra versatile, it could possibly deal with every little thing from a small screw to a big automotive half. Not like human fingers, the fingers can bend inward as much as 90 levels and backward, permitting for extra complicated greedy strategies. The gripper is available in left and proper variations, identical to our personal fingers, so Atlas can at all times discover the perfect angle for the job.
Tactile sensing revolutionizes grip by placing sensors in a high-friction elastomer – a rubbery materials that’s a grip floor and a pressure sensor. These sensors are a way of contact, so Atlas can really feel how a lot strain is being utilized. That is key for dealing with delicate objects like espresso cups with out crushing them or a heavy device from slipping. The sensors additionally inform Atlas when an object falls out of its grasp so it could possibly alter on the fly. A palm-mounted digital camera is an additional layer of consciousness so Atlas can “see” what it’s greedy and alter its grip in actual time.
Why three fingers as a substitute of 5? Three fingers together with the opposable thumb is a steadiness between performance and ease. Extra fingers may do extra complicated duties however would enhance complexity, price and potential failure factors. A 3 finger gripper can deal with giant heavy objects by distributing stress throughout many contact factors and the thumb permits for 2 finger pinches on small objects.
