The 7-axis walking track of the robot is the seventh motor other than the 6-axis industrial robot ontology (which can be linked with the 6 motors of the body) is referred to as the "7th axis" for short. The 7th-axis motor drives the robot body to walk on the track. It is used for multi-axis linkage coordination operations such as robot welding and handling. Multi-axis linkage is used to improve the operation time of the robot in complex production processes and better expand the utilization rate of the robot.
