Initially, the exoskeleton technology was developed by General Electric of the United States to develop the Hardiman full-body powered exoskeleton to enable a human to lift heavy objects. The concept was adopted by others who started to develop locomotor exoskeletons that supported the human musculoskeletal system for rehabilitation and enabled an injured or paraplegic person to stand and walk.

In recent years, with the development of exoskeleton robot technology and the gradual expansion of insurance coverage and subsidies, exoskeleton robots have been widely used and praised by patients in the medical field. As the core component of the robot joint, the application of harmonic drive in exoskeleton robot receives more and more trust from manufacturers. It can provide protection and support for the disabled through strain wave gear transmission, so that the disabled can live a normal life, reduce the work pressure of the nursing staff, and improve the quality of life of the disabled.
There are many forms of exoskeleton robots, including upper body, lower body or whole body exoskeleton. The transmission mode of the main exoskeleton robot is mostly in the form of motor and harmonic gearbox directly connected to the joints. The joints of the robot are adjusted through the harmonic drive gear to ensure the speed of movement and output torque to maintain normal operation.

The lower extremity exoskeleton robot consists of a connecting frame and two lower extremity exoskeletons, wherein the lower extremity exoskeleton mainly consists of hip joints, knee joints and ankle joints. The motor and harmonic drive gearbox are mainly used in the hip and knee joints of the exoskeleton,The wave gears is connected with the servo motor, which not only simplifies the structure, but also has the characteristics of buffering, vibration absorption and stable transmission.
The exoskeleton robot for hemiplegic patients consists of a bracket, a waist device set on the bracket and leg devices on both sides. The design of the device uses a frameless motor and a harmonic drive gearbox, which not only has a light joint structure, but also has a large enough Output torque, the strain wave gearbox is used as a part of the shell, so that the volume of the entire affected leg joint is also very small, reducing the load on the affected leg, and the harmonic gearbox is driven by the motor to drive its flexion and extension or straightening action.
Exoskeleton robot is an intelligent mechanical structure which is worn outside the user's body. It can combine human perception, thinking, movement and other organs with the machine's perception system, intelligent processing center, and control execution system to improve the physical function of the human body. The purpose of improving physical fitness is a kind of wearable robot that can realize the combination of man and machine. The form of motor and strain wave directly connected to the joint provides mechanical power for the exoskeleton robot, so that it has sufficient stability, load-bearing capacity, flexibility and adaptability.In recent years, exoskeleton robots have developed rapidly, playing a huge role in military, medical and industrial fields, and have broad application scenarios.
