Q: BUNKER PRO 2.0 starts up normally, but the robot does not move when using the remote controller?

A:

First, verify whether the power switch has been released (Q2 on the rear electrical panel). Then, check if the mode selection switch (top-left of the remote controller) is set to the correct control mode.

Q: Remote control works normally and the chassis feedback (status and motion data) is received correctly, but the vehicle does not respond to CAN control commands or mode switch instructions?

A:

If the remote controller works correctly and chassis feedback is received properly, this indicates the motion control and CAN communication are functioning. Please verify whether the control mode has been successfully switched to CAN mode before sending control commands.

Q: When using CAN bus communication, the chassis feedback is normal, but the robot does not respond to the control commands?

A:

BUNKER PRO 2.0 has a built-in communication protection mechanism. If the chassis receives a CAN control frame and does not receive a subsequent control frame within 500 ms, it will enter a communication protection state, and the robot will stop (speed = 0). Therefore, control commands from the upper computer must be sent cyclically.
