If the buttons on the remote control don't work after the robot turns on, there are several possibilities: if the remote control doesn't work, but the robot can find the charging base normally, that would be the remote control is out of power or damaged; if the remote control doesn't work, and the robot doesn't rotate to calibrate when looking for the charging base, it means that the receiver head on the robot keypad/display board is malfunction, you need to replace the keypad or receiver head.
