The development pace of therobot technology has been further accelerated with the help of model simulation. Based on the application scene and motor control model provided by LabVIEW, an algorithm model for robot trajectory deduction is designed. For a wheeled robot, according to the speeds of the left and right wheels, the model calculates the velocity of the robot in the application scene. Then the model reflects the position change of the robot in the application scene through the track coordinates in the world coordinate system. This model can assess the motor motion control effect and test the control system of wheeled robot by detecting the trajectory change in the world coordinate system.
