Pressing gently on the side, carefully remove the 2 pin connection for the 3 remaining IR sensors. The PCB should now be fully disconnected from all components, aside from the start/stop button for which the connection cannot be removed without soldering.

Using a small Phillips screwdriver, remove the 2 screws from the PCB.

Placing your fingers on the side to avoid damaging the PCB, lift away from the robot. Be careful to not pull on the yellow wire connecting it to the start/stop button.
