The robot.
The robot itself is actually rather simple. It consists of two servo-driven wheels, a breakout board for the ATMega 128 Atmel microprocessor, an LCD screen, battery packs, and three sensors.
The first sensor is a bump switch, to determine if the robot has run into a wall. This switch also begins the robot’s trek through the game board.
The second sensor is a line-follower, which ensures that the robot will follow an accurate and predictable path through the board.
The third sensor is a barcode reader, mounted in conjunction with a mirror to read the cards played on the board. These are used to determine the type of card played, as well as to prevent “infinite loops” from occurring.
Here’s a picture! It’s not quite done yet, but we’re getting close…
