Measurement and Application of Industrial Robot Jitter.

Industrial robots are widely used in automobile and auto parts manufacturing, mechanical processing industry, electronic and electrical industry, rubber and plastic industry and many other critical areas. The jitter of robots during the operation process may lead to the severe decline in important parameters such as positioning accuracy and trajectory accuracy, which is destructive for fine work such as welding, laser cutting, grinding, and polishing. The jitter characteristic is an important indicator for evaluating the comprehensive performance of industrial robots, and it is an urgent issue to be solved.
