Replacing Bob's Remote Control Module
To replace the remote control module on Bob Pro, you’ll need a new remote control module and a Phillips Head Screwdriver.
Power off Bob before starting your repair. Press in the bumper while holding down the cover button. After 5 seconds, Bob will beep, and the cover light will turn off when released.
Next, remove the dustbin. Grasp the tab on the back of Bob and slide the dustbin out. Then, flip Bob upside down so the wheels are facing up.
Remove the 6 large screws from the underside of Bob. Keep all screws and parts removed from Bob safely aside for later reassembly.
Next, remove the 2 small screws that hold Bob’s side casing. Pull to detach each piece, using a flat head screwdriver for leverage, if necessary. Bob's casing is no longer secure.
Carefully flip Bob back onto his wheels and lift the cover to expose the mainboard. Disconnect the circuit plug attaching the cover to the mainboard.
Next, disconnect all of the mainboard’s circuit plugs.
You'll be reattaching all the plugs later, so take note of all the connections.
Grip each plug and pull to remove, without placing stress on the wiring.
When done, remove the 4 screws holding the mainboard.
Then, lift the mainboard out.
The remote control module is found behind the front wheel.
Remove the screw holding the small circuit board. Then, slide it up to remove completely.
Slide your new circuit board all the way down into the small holder inside Bob. Reinstall the screw removed previously.
Next, align the mainboard with the 4 screw posts inside Bob. When the mainboard sits flat, install the 4 screws removed previously.
Then, reconnect all the circuit plugs to the mainboard. The order of the plugs on the left edge from top to bottom is as shown in the video.
Tuck the wires for the 2 lower circuit plugs under the hook inside Bob.
The order of the plugs along the top edge of the main board, from Bob’s left to right, is as shown in the video.
Take note of the colors of each wire to ensure you replace all of the circuit plugs correctly.
The order of the plugs along the right edge of the mainboard is as seen in the video.
Remember to tuck the wires for the lower 2 circuit plugs under the hook inside Bob.
The order of the plugs along the bottom ledge, from Bob’s left to right, is as seen in the video. Take note of any empty spaces on the mainboard.
When all circuit plugs are securely connected, you’re ready to close Bob.
Reconnect the cover's circuit plug to the mainboard. Lay the cover down, so it’s slightly below the bumper’s top edge. The bumper should move when pressed in.
Flip Bob upside down and install all 6 large screws on Bob's underside.
Align the side casing pieces with the screw holes on Bob’s underside. Then, flip Bob onto his wheels and snap the pieces onto Bob’s sides. Next, install the 2 small screws removed previously.
Then, flip Bob onto his wheels and slide the dustbin back in place to complete your repair.
Press and hold the cover button for 3 seconds to turn Bob back on, and congratulations! You’ve just replaced Bob Pro’s remote control module.
