1. SCOUT MINI is started up correctly, but why cannot the RC transmitter control the vehicle body to move?

• First, check whether the drive power supply is in normal condition, whether the drive power switch is pressed down and whether E-stop switches are released; then, check whether the control mode selected with the top left mode selection switch on the RC transmitter is correct.

1. SCOUT MINI RC transmitter is in normal condition, and the information about chassis status and movement is all fed back correctly, but when the control frame protocol is issued, why cannot the vehicle body control mode be switched and the chassis respond to the control frame protocol?

• Normally, if SCOUT MINI can be controlled by a RC transmitter, it means the chassis movement is under proper control; if the chassis feedback frame can be accepted, it means CAN extension link is in normal condition. Please check the CAN control frame sent to see whether the data check is correct and whether the control mode is command control mode. You can check the status of error flag from the error bit in the chassis status feedback frame.

1. SCOUT MINI gives "beep-beep-beep..." sound when running, how to deal with this problem?

• If SCOUT MINI give this "beep-beep-beep" sound continuously, it means the battery is in the alarm voltage state. Please charge the battery in time. Once other related sound occurs, there may be internal errors. You can check related error codes via the CAN bus or communicate with related technical personnel.

1. Is the tire wear of SCOUT MINI is normally seen when it is running?

• The tire wear of SCOUT MINI is normally seen when it is running. As SCOUT MINI is based on the four-wheel differential steering design, sliding friction and rolling friction both occur when the vehicle body rotates. If the floor is not smooth but rough, tire surfaces will be worn out. In order to reduce or slow down the wear, small-angle turning can be conducted for less turning on a pivot.

1. When communication is implemented via CAN bus, the chassis feedback command is issued correctly, but why does not the vehicle respond to the control command?

• There is a communication protection mechanism inside SCOUT MINI, which means the chassis is provided with timeout protection when processing external CAN control commands. Suppose the vehicle receives one frame of communication protocol, but it does no receive the next frame of control command after 500 ms. In this case, it will enter communication protection mode and set the speed to 0. Therefore, commands from upper computer must be issued periodically
