Why It Is Necessary
to Detect the Trajectory
of Medical Robots？

It is necessary to measure the motion coordinates of medical robots and compare them with the automatic control system. Given that most of the robots are applied to perform surgical operations which require high precision and bear high risk , the accuracy and stability of their trajectories have direct impact to the success of the surgery as well as the safety of patients. Through trajectory detection, we can monitor whether they are in line with the preset requirement or not, thereby enhancing the precision and safety during the surgery.

How to Detect the Trajectory of Medical Robots

The PMT Portable Coordinate Measuring Machine is used to conduct contact measurement on the end-effector of the medical robot. It allows us to obtain the precise position of the spacial end-effector of the robot as well as motion dimensions. (It is also important to take into consideration the impact of the contact force between the ball probe and the end-effector of the robot on the measurement results.)
