Development of Chassis and Wheel 

I already have a chassis complete with a pair of servo wheel. Unfortunately, this chassis is too big to navigate through the maze and the servo wheel did not fit with the shaft of the stepper motor. So, I have to do some modification on the chassis and the wheel. The original chassis is 160mm x 130mm. This chassis has to be cut into 90mm x 90mm to enable the micromouse to navigate through the maze without hitting the maze wall. Meanwhile for the wheel, I have to enlarge the opening to 5mm to fit the stepper motor shaft into the wheel. To do this I use a mini grinder and a calliper to grind and measure the opening.
