 If both calibrations were precise the robot should be able to navigate precisely around in a cartesian coordinate system. The testrun is shown on the figure below together with a video of the performance. There seems to be a weakness in the rotations, but the distance is very accurate. One way to improve the precision during rotations could be to add a compass.    If both calibrations were precise the robot should be able to navigate precisely around in a cartesian coordinate system.

 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.
