Error occurs during ESTUN robot movement in master control calibration

When attempting to calibrate the ESTUN robot after successfully establishing master-control communication, an error occurs: Failed to move ESTUN_xxxx: Failed to call “forward”.

The robot interface is called at an excessively high frequency, resulting in a failure of the robot system response. Try modifying the robotserver program to reduce the call frequency to once every 1~3 seconds.


  1. Open the Mech-Center/Robot_Server/src/robot/estun/ file with Notepad.
  2. Change sleep(0.3) into sleep(3) in line 156.
  3. Save the change and restart Mech-Vision.
