machine design
I opted to use Pololu motor drivers and a custom designed circuit board that is based on an Atmega 328p microcontroller. I made the design on eagle as shown. Since sonme routes were difficult to make on the pcb the board i madeit two sided with the intention of using jumpers .

from the board we were able to extract the traces as shown
Eagle board
After etching and stuffing the board it came out as shown
fabbed board
Below is a video of the working machine
