Hardware - Motor and Chassis
I constructed the motor driver circuit using ULN2803A and test it with stepper motor and it works. Below is the picture of the testing circuit:

The chassis that I already have is too big to navigate through the maze. If I want to use it, I have to cut it smaller but I’m afraid that it will break. The chassis had cracked during modification for last semester demo. Therefore, I decided to use perspek for the chassis as it can be cut easily and the most important is, it is very light. Perspek can be found in various size and thickness. I decided to buy a 5mm perspek in A3 size at The Art Shop Taman Melawati. I also bought a special cutter to cut the perspek.
