Abstract: An assistive exoskeleton glove system for a hand of an individual is described. In one example, the system includes a brace mount and a finger brace including a seat platform mechanically coupled to the brace mount. The finger brace can include a plurality of brace links, a plurality of constraint links, and an actuation lever. The system can also include an actuator mechanically coupled to the actuation lever and configured to articulate the finger brace over a predetermined range of motion. The range of motion can be tailored for different purposes. The system can also include finger abduction and adduction mechanisms, a thumb brace, a thumb flexion actuator, and a control system. The control system can be configured to detect a relative difference in feedback signals provided from target and offset encoders on the finger brace, as an input to control the actuator, and real-time grasping forces among other inputs.
