Remove the two 22.0 mm screws on the bottom-front of the robot using a Phillips #1 screwdriver.

Edit

These screws have a non-threaded top. So they’ll move after unscrewing but not come out.

At this stage it’s best to lift them and continue to unscrew until they’re removed as this makes removing the cover easier.

Same for the other two 15mm screws.
