Problems solved by technology

However, the inclination sensor lacks real-time performance in dynamic angle detection, and complex calculations are required to solve the motion angle

The shoulder joint angle detection based on the inclination sensor is not accurate enough when the shoulder joint moves, and it cannot meet people's real-time control of shoulder movement needs.
