Replacing Touch Sensors - bObi Pet

For this repair, you will need a Phillips head screwdriver and a set of replacement touch sensors.

First, flip bObi's power switch OFF.

Next, remove bObi's front wheel to access one of the screws holding her together. Turn bObi's front wheel towards her bumper and, using a screwdriver for leverage, grip the wheel firmly and pull it up.

Remove the screw located beneath bObi's wheel.

Detach bObi's dustbin and remove the 2 screws on either side of it.

Remove the 2 triangular corner pieces held down by these screws.

Pull the main brush compartment forward to expose the red fastener behind bObi's main brushes. Remove the 2 smaller screws holding the red fastener in place.

Lift bObi's brush compartment up and out. To detach her brush compartment completely, unplug it from bObi by pulling at the circuit junction.

Remove the 4 screws located beneath bObi's main brushes. 

Remove the 2 screws securing the red contact point fastener onto bObi, and pull off the fastener.

Flip bObi back onto her wheels and lift her cover up. There are 2 circuit plugs which must be removed to separate bObi's cover completely: a yellow-wired circuit plug connected to the left side of bObi's mainboard, and a white-wired circuit plug connected to the center of bObi's mainboard.

Disconnect the touch sensors from the circuit board on bObi's cover. The left touch sensors are connected to the left side of circuit board; the right touch sensors are connected to the right side of the circuit board.

Feed the wires along the inside of bObi's cover, freeing them from each black plastic hook.

Feed the wires behind the post at the end of the bumper before pulling them to the side to disconnect them.

Now, attach the new set of sensors and tuck the wires behind the post at the end of the bumper. The red wire plugs into the top connector; the white wire plugs into the bottom connector.

Feed the wires back through the hooks.

Reattach the touch sensors to their corresponding spot on the circuit board.

Now you’re ready to put bObi’s cover back together. Reconnect the white-wired circuit plug to the center of bObi's mainboard and the yellow-wired circuit plug to the left side of her board. Press each circuit plug firmly until they lock in their holders.

Carefully replace bObi’s cover. Make sure its edges align precisely before laying down the contact point fastener and reinstallling its 2 screws.

Next, reinstall the 4 screws located beneath bObi's brush compartment.

Reattach bObi's brush compartment.

Line up the red brush fastener on bObi and replace its 2 smaller screws.

Lay the 2 corner pieces down.

Reinstall the 2 screws on either side of bObi's dustbin.

Reinstall the screw located beneath bObi's front wheel.

Lastly, replace bObi's front wheel by turning it towards her bumper and pressing down.

Your repair is now complete!
