Grasping the Future with a Robotic Hand-Arm Combo

The robot arm-hand unit.

In the past, Patel notes, robot arms and hands have always been studied as separate sub-systems. “I think this was the first time that anyone has unified them in a single model and quantitatively characterized its benefits."

Yale University's Daniel Rakita, Aaron Doll, and Vatsal Patel have created a robotic hand-arm combination that uses algorithms to optimize its degrees of freedom and control though unified movement.

Having greater degrees of freedom indicates greater manipulability, flexibility, and general dexterity in the robotic system, which it can use in a wider range of options for completing tasks.

The quality of those options also increases as the degrees of freedom increase.

Rakita said, "This suggests that our algorithms are able to identify important criteria, and perhaps more fundamentally, complex arms and hands can indeed coordinate to achieve more effective movements together."
