CoasterBot Contest

We challenged you to design a robot using a coaster (CD or DVD) as the development platform, or main body component. The bot had to be able to navigate space, avoid obstacles and display an extra sensing system. From there, originality and innovation guided the designers to create the coolest bots ever! The designers had a blast designing and building, and the Jameco team had lots of fun judging the videos. Here are the top three entries and a few other favorites.

FIRST PRIZE: THE TERMINATOR from Eric of Torrance, California

The Terminator

The Terminator is a BASIC Stamp 2E controlled-wheeled chassis that uses a laser sensor to locate targets and a servo-based gun to knock them out with rubber bands.

THIRD PRIZE: COBBER from Edward of Victorville, California

The Cobbler

The Cobber serves up the literal meaning of coaster by delivering a beverage to a destination point. The Cobber starts when a light sensor is activated and uses ultrasonic distance sensors to detect boxes in its way. Cobber finds its delivery target with a color detecting sensor.
