Dark-colored carpeting and certain floor patterns may seem
like edges to Bob’s edge sensors.
If you notice that Bob stops with TROUBLE NR 04 on your carpet, then you may need to
temporarily deactivate them, or “blindfold” Bob by covering his ground detection
sensors. Bob’s edge sensors are located on his underbelly, near his bumper.
To deactivate Bob’s edge sensors:
Deactivate Edge Sensors
Caution: When the edge sensors
have been deactivated, Bob will
be unable to detect stairs or
sharp drops.
Flip Bob’s power switch ON. Hold down
the UV button on Bob’s cover. The 5 bars
on top of Bob’s screen will begin to flash.
After the 5 bars flash 7 times and remain
still, release the UV button. The 5 bars
will remain on. This means Bob’s edge
sensors are deactivated.
