PCT Application filed July 2020 (available on request)
A compact, robust, and energy efficient differential system for distributing torque from one electric motor across four outputs. Designed to increase the actuation and grasping capabilities of soft exoskeleton gloves and adaptive prosthetic systems while guaranteeing reduced cost and complexity.
Soft, underactuated, and wearable robotic exoskeleton gloves can improve the capabilities of healthy individuals or assist people suffering from neurological and musculoskeletal diseases. Most existing solutions utilise individual motors to control each finger independently, which increases weight, cost, and complexity. Commercially available prosthetic devices use individual motors for every finger and rigid transmission systems that transfer the forces to the prosthetic fingertips. Such design choices make the prostheses heavy, expensive, bulky, difficult to maintain, hard to operate, and provide limited operation autonomy (due to increased power consumption).
Typically, a differential mechanism has two outputs and its most popular application is in the automobile industry, where the differential allows the wheels to rotate at different speeds.
