1. TRACER MINI starts normally, but the vehicle body does not move with the remote control?

    First, confirm whether the drive power supply is normal and whether the emergency stop switch is released; then confirm whether the control mode selected by the mode selection switch on the upper left side of the remote control is correct.

  2. When the TRACER MINI remote control is normal, the chassis state and motion information feedback is normal, and the control frame protocol is issued, why the vehicle body control mode cannot be switched, and the chassis does not respond to the control frame protocol?

    Under normal circumstances, if TRACER MINI can be controlled by the remote control, it means that the chassis motion control is normal, and it can receive the feedback frame of the chassis, which means that the CAN extension link is normal. Please check the sent CAN control frame to see if the command control mode is switched. You can check the status of the error flag in the error bit in the state frame fed back by the chassis.

  3. TRACER makes a "drip-drip-drip..." sound during operation, what should I do?

    If the TRACER MINI emits continuous "drip-drip-drip..." sound, it indicates that the battery is already in the alarm voltage state, please charge it in time; after the relevant sound appears, there may also be an internal related error, you can check the related error through the CAN bus code or communicate with relevant technical personnel.

  4. When the relevant communication is carried out through the CAN bus, and the chassis feedback command is normal, why does the vehicle do not respond after the control is issued?

    TRACER MINI has a communication protection mechanism inside. Chassis has a timeout protection mechanism when dealing with external CAN control commands. Assuming that after the vehicle receives a frame of communication protocol, it does not receive the next frame of control commands for more than 500MS, and it will enter the communication protection with a speed of 0, so the command from the host computer must be periodically issued.
