Abstract:
This paper proposes a real-time processing algorithm which estimates a subject knee moments using some joint angle data and EMGs of involved muscles. This algorithm will be essential part for the control system design of exoskeletal robotic devices. In order for this algorithm to accurately predict joint moments, it is necessary to know the one's musculo-skeletal properties, which is virtually impossible. An optimization process is used to determine one's musculo-tendon characteristics. The proposed method is evaluated through the comparison with experimental results.
