Bep: The robot drives backward

If the robot drives backward, this may be due to;

• Dark spots (e.g., a mat) on the floor. The robot could see these as a drop-off, and the anti-fall sensors could then intervene.
• Bright sunlight can create a high contrast on the floor. The robot could then think there is a drop-off and start driving backward.

• The robot's bumper sensors cannot see properly.
  • Clean the bumper thoroughly.
  • Press the bumper firmly a few times at the location of the side brushes. The switch behind the bumper may be stuck.
• The fall sensors detect something.
  • Clean the fall sensors thoroughly.
