Joint Impedance

Joint impedance, representing the resistance to movement at a joint (combining stiffness and damping), is a key factor in understanding motor control and human-robot interaction. Current research focuses on identifying and modeling joint impedance across various body segments (e.g., elbow, hip, knee) using techniques like force perturbations and advanced musculoskeletal models, often incorporating reinforcement learning algorithms for improved simulation and control. This work is crucial for developing more effective prosthetics, exoskeletons, and rehabilitation therapies by enabling the design of devices that better mimic natural joint behavior and adapt to dynamic environments.
