A medical robot is a robot used in the medical sciences. They include surgical robots. Since it is introduction in 1996, over the past 20 years, medical robot has undergone several generations of changes. Today, more types of medical robots have begun to appear. 

In the current medical robot market, European and American companies occupy most of the market share. Chinese medical robots are still in the research and development or clinical trial stage, and medical robot products haven't realized scale.
Global medical robot market was valued at 13.65 Billion US$ in 2018 and is projected to reach 31.77 Billion US$ by 2024, at a CAGR of 15.12% during the forecast period.

Medical robots can be divided into four categories: surgical robots, rehabilitation robots, auxiliary robots and service robots:
Surgical robot:
1. Fine operation, small wounds, low bleeding volume, short use time
2. Increase doctor's field of vision and reduce hand tremor
3. Reduce the cost of attending surgical staff

Rehabilitation robot
1. Effectively promote the functional reorganization, compensation and regeneration of the mental system
2. Effectively relieve muscle atrophy and joint atrophy
3. Optimize medical resources

Auxiliary robot
1. Can sense and process sensory information and give users feedback
2. Meet the needs of patients, people with reduced mobility, or older people

Service robot
1. Common medical service robots are medical transport robots and disinfection and sterilization robots
2. Can help medical staff to share some heavy and tedious transportation work, improve the efficiency of medical staff
