START-BOT

This robot was made with a sound sensor (because it was the first robot in the chain reaction) and two motors with large wheels to support the NXT. A third small wheel was mounted in the front of the bot for stability. Mounted on the top was a third wheel that was horizontally placed, such that when the sound sensor was triggered, the robot would drive forward, so that the mounted wheel would connect with the button on the second robot. Paper was taped to the wheel to increase the consistency of the button press.
