The aim is to develop a robotic system to assist in wrist rehabilitation by improving mobility and strength after injury or surgery.
Developed a 3-DOF robotic system with AFC-PID control for wrist rehabilitation.
Implemented simulation and experimental trials with diverse participants.
The system operates in passive, assistive, and resistive modes to facilitate muscle engagement.
Achieved maximum torque of 1.00 N·m with angular velocity of 0.55 rad/s.
Reduced perceived joint stiffness by up to 15% across treatment modes.
Demonstrated high repeatability with an ICC value exceeding 0.98.
