For this repair, you will need a Phillips head screwdriver and replacement cover.
Make sure Bob’s side power switch is turned OFF and flip him over onto a flat surface. Remove the screw securing Bob’s main brush in place.
Remove Bob’s main brush to access and remove the screw located beneath it (depending on Bob's model, there may be 2 screws).
Remove the 5 screws lining Bob’s underside.
Flip Bob back onto his wheels and lift his cover up. Depending on your Bob's model, you may need to remove 3 or 4 circuit plugs to detach the cover completely. Pinch the small white tab on the side of each circuit plug and pull upwards to remove.
For older versions of Bob, you must remove 3 circuit plugs from the mainboard:
For newer versions of Bob, you must remove 4 circuit plugs from the mainboard:
Slide Bob’s power inlet out and place the cover aside.
To replace Bob’s cover, you must remove the touch sensors, bumper, and LCD screen from his old cover.
Remove the two screws holding the touch sensors in place.
Next, lift each sensor out.
Remove the 4 screws holding Bob's bumper in place (the screw on the left is hidden inside a screw post).
Remove the two spring pieces inside Bob’s cover before detaching his bumper.
Bob’s bumper is composed of an inner wired piece and a large exterior cover.
Next remove the screen from Bob's old cover. Remove the 5 screws securing the screen in place.
Lift all of the screen’s pieces out: the cover plate for the buttons, the LCD screen, and, 3 springs.
Reattach the screen to Bob's new cover. First, place down the cover plate for the buttons, then place the black transmitter in the circular space above the screen. Place the 3 springs between the plus signs on the cover plate.
Lastly, place the LCD screen on top of the springs and replace all 5 screws securing it in place. Make sure to line up the holes on the screen with the screw posts on Bob’s cover.
Now you may attach Bob’s bumper to his new cover. Place the large bumper piece underneath Bob’s cover so its screw posts align with the four holes around the cover’s front edge.
Lay the wired piece on top so its screw holes line up precisely with the screw posts on Bob’s outer bumper piece.
Replace all 4 screws lining the bumper's edge.
Replace the bumper's 2 springs as well.
Lastly, you may attach the touch sensors to the new cover. Place the touch sensors in the open spaces and replace the 2 screws. Remember to keep the black wires on the inside and the red/white wires on the outside.
Now you’re ready to put Bob’s cover back together. First, reattach all the circuit plugs you removed to separate Bob's cover. Press down on each circuit plug to ensure it securely locks in place.
For older versions of Bob, reattach 3 circuit plugs to the mainboard:
For newer versions of Bob, reattach 4 circuit plugs to the mainboard:
Before closing Bob's cover, slide his power inlet back in its place.
Carefully realign the edges of Bob’s cover and flip him onto his back. Replace the 5 screws on his underside to seal his cover together.
Replace the 1 or 2 screws located beneath Bob's main brush.
Place the main brush back in its compartment. Attach the end piece first
and align the square end with the square-shaped notch inside Bob.
Lastly, replace the screw securing Bob's main brush in place and your repair is complete!
