Intelligent muscle strength and gait assistance robot

Intelligent muscle strength and gait assistance robot with joint actuators mounted directly on the exoskeleton

This technology is an intelligent muscle strength and gait assistance robot that integrates an exoskeleton worn on the user's lower body with a caster walker as a gait aid via an arm, and minimizes power transmission distance by installing actuators directly on the hip and knee joints.

Conventional gait aids suffer from low mechanical efficiency and complex structures due to the long power transmission distance between the actuator and the joint, as well as risks of detachment and structural instability caused by the separation of the arm and the exoskeleton.

This technology proposes a method of positioning the joint actuators on the exoskeleton rather than the arm and integrating the arm and exoskeleton into a single unit. It can be applied to lower limb rehabilitation and muscle strengthening training, maximizing power transmission efficiency, simplifying control, and ensuring structural stability.

Key Features:

• Exoskeleton equipped with a pair of frames and hip and knee joints that rotate the frames
• Configuration where waist, thigh, and calf braces are fastened to the frame
• Caster walker unit that is mobile and equipped with handles to provide stable gait assistance to the user
• A pair of arms integrally coupled to the frame, with both ends fastened to the exoskeleton and the caster walker, respectively
