ROMBot driving through maze using mouse sensor and stored coordinates

Final test of ROMBot build using arduino uno, H-bridge (L293D), parts form 2 old CD-ROMs, old optical mouse, couple screws, wheels from Castorama, IR receiver and old TV remote used for training procedure. Robot uses mouse optical flow sensor to calculate its position which is much more precise than using wheels encoders and wheel slip is not a problem as it is a case with wheel encoders.

ROMBot can communicate with PC using bluetooth and raport its posiotion, heading and PWM values for each motor. Data is visualized using specially created LabView application.
