 There were magnetic disturbances at the test area, which of course made the compass inaccurate.
-The precision of the compass was tested by placing a marker on the robot. In this way we can simply measure the deviation by letting the robot turn on a whiteboard and measuring the angle.
+The precision of the compass was tested by placing a marker on the robot. In this way we can simply measure the deviation by letting the robot turn on a whiteboard and measuring the angle.

The acceleration was too high for this surface and one could have reduced the motor power.
