This paper puts forward a real-time angular tracking (motion capture) system for a low cost upper limb exosuit based on sensor fusion; which is integrated by an elastic sleeve-mitten, two inertial measurement units (IMU), two flex sensors and a wireless communication system. The device can accurately detect the angular position of the shoulder (flexion-extension, abduction-adduction and internal-external rotation), elbow (flexion-extension and forearm supination-pronation), and wrist (flexion-extension) joints. In addition, the state of the hand (opened-closed). Finaly a PID controller is applied to the exosuit in order to replicate the movements performed by the arm into a 6 DOF robot arm.
