The lower limb multi-degree-of-freedom exoskeleton is an innovative wearable robotic device designed to improve lower limb mobility and support. By integrating multi-DOF joint actuation and sensing technology, it accurately mimics natural gait and provides dynamic support for ankle, knee and hip joints, helping users achieve greater autonomy in rehabilitation, mobility assistance and enhanced motor performance. The exoskeleton is widely used in the rehabilitation of the elderly, athlete training, lower limb injury rehabilitation, and mobility assistance for special populations, aiming to improve lower limb dysfunction, improve quality of life and work efficiency.
