Trouble Number 05: Wall Sensors
Trouble number 05 means Bob’s wall
sensors are blocked or dirty.
What to do:
Do a visual check on the transparent stripe
on Bob’s bumper. If it is too dirty for you to
see what is behind it, wipe it with a clean,
damp cloth.
To ensure nothing is jammed under the
bumper, gently tap it and use compressed
air to clear it of debris. If the issue persists,
try running a checkup test on Bob.
Trouble Number 06: Touch Sensors
Trouble number 06 pertains to Bob’s touch
sensors. It is likely that a small piece of
debris is trapped under the bumper.
What to do:
Slowly and carefully tap on Bob’s bumper
to clear out any obstructions. Use
compressed air to clear it of dust and
debris.
Press on both ends of the front bumper until you hear a tiny ‘click’ sound. If the
bumper is not clicking on its ends, it is possible that one or more of Bob’s touch
sensors has a broken arm and needs to be replaced.
