5. Q&A
Q:
SCOUT MINI is started up correctly, but why cannot the RC transmitter control the
vehicle body to move?
A:
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.
Q:
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?
A:
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.
Q:
SCOUT MINI gives "beep-beep-beep..." sound when running, how to deal with this
problem?
A:
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.
Q:
Is the tire wear of SCOUT MINI is normally seen when it is running?
A:
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.
Q:
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?
A:
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.
