When Bob faces an uncomfortable situation, he will notify you by displaying TROUBLE NR., coupled with a two-digit number, on his screen. Each number corresponds to a certain issue Bob is having.
Trouble Number 00: Left Wheel
What to do:
- Start by checking the wheel for jamming. Use the cleaning tool or compressed air to remove any debris that may be jamming the wheel. If this does not solve the problem and Bob still displays Trouble Number 00, run a checkup test and see how the wheel performs.
