Problems solved by technology

The disadvantage of this method is that the installation of the sensor is inflexible. For many motion parameters that are inconvenient to install the sensor, only indirect analysis and measurement can be performed; Distortion of motion parameters; detection accuracy and efficiency are not high enough; in some special cases, it is impossible to analyze mechanism kinematics and dynamics by this method
