Here are some pictures of my completed micromouse chassis, along with all the boards.

Everything on the chassis is mounted using velcro, for easy attachment and removal.

There are 4 seperate boards that make up the control circuitry:

  • Sensor board, containing 4 IR photoreflectors, which attaches to the main control board.
  • The stepper driver board, which uses an ATTiny2313 to sequence 2 step / direction into the correct outputs to drive the motors.
  • The Power regulation board, which carries an LM1084 3.3V regulator, to drive the motors, and a LM2940CT 5V low dropout regulator, to drive the electronics.
  • The main control board, which contains an ATMega16, and controls all the running of the robot, and controls all the maze searching and running algorithms.
