Error Consideration

The drive system is prone to errors. Even if you use stepper motors, errors can still be introduced due to an imperfect maze floor (bumps and dust). Furthermore, the competition rules specify that the maze may be constructed with up to 5% of tolerance.

How much error is too much error? It all depends on the limits at which errors can still be corrected and your tolerance of risks. We will discuss errors and error correction in depth later. For now, having a linear resolution of 1mm to 2mm is a reasonable assumption.
