Intelligent Strength and Gait Assistance Robot

Intelligent Strength and Gait Assistance Robot with Direct Knee-Joint Drive and Linear Guide

This technology features a gait assistance robot that combines an exoskeleton worn on the user's lower body with a caster walker via an arm. By mounting the knee-joint actuator directly onto the knee and installing the hip-joint actuator with a linear guide, the power transmission distance is significantly reduced.

Conventional technologies suffer from long power transmission distances between the actuator and the joint, resulting in low mechanical efficiency and output, complex control, interference in the range of motion, and structural instability.

This technology proposes a method of directly coupling the actuator to the knee joint and applying a linear guide to the hip-joint actuator to provide longitudinal degrees of freedom to the arm. It can be applied to gait rehabilitation and strength training for the general public, patients, and the elderly, improving both output and stability while reducing power loss and interference.

Key Features:

• An exoskeleton equipped with a pair of frames, hip and knee joints that rotate the frames, and braces
• A caster walker equipped with wheels driven by a motor to assist the user's gait
• An arm configured to correspond to the pair of frames, with both ends fastened to the exoskeleton and the caster walker, respectively
• A joint actuator installed on the arm to transmit rotational force to the hip joint and directly coupled to the knee joint
