Do you see any text on the display? Are you turning the thumbwheel
(the black knob next to the serail port connector)?

The IntelliBrain-Bot, as with any robot, has limited precision and is
subject to meeasurement and control errors, such as slippage of the
wheels. This is one of the challenging aspects of robotics that
makes the field interesting and challenging.

You can improve the precision of the IntelliBrain-Bot's navigation by
upgrading the wheel encoders. Nubotics makes some very nice encoders.
