Going backward on its back is expected behavior, as the sensor in this situation measures a hgih raw value of reflected light and therefore assumes that the sensor is far away from the ground and tries to flip itself up by setting full speed backwards on its motors. This doesn't work as the robot doesn't have enouyght power.

At first we placed the robot in the middle of the room, started the non-modified program, calibrated it with support from our hands. This attemp made the robot fell over - and thereby not balancing - almost immediately as seen in video 2.

From this attempt we decided that we didn't trust our abilites to calibrate the robot in the dark using just our hands and eyes to measure when the robot was standing upright, why we decided to do calibration using the bathroom door.
