Gear Box

75:1 Gear Ratio for a careful balance of torque and speed

Mechanical In-Only Gate

A purely mechanical gate that opens in only to easily collect and store small balls by rolling over them

Servo Controlled Gate Opener

A simple servo controlled mechanism lifts the mechanical gate when we are about to score.

Bump And Light Sensors

A bump sensor mounted on the front tells us when the robot has hit a wall. Light sensors help orient the robot and find lines.

Corner Wheels

Wheels placed on the four corners of our robot help us turn out of walls on the game board easily

Propeller

It turns. Why not?

Steering Wheel

The most important feature. Allows our cute lego men couple, Jeff and Ian, to drive the robot.

(Actually it is just a servo that turns a steering wheel when we turn. Again, why not?)
