Robot 5 • The Three-in-One Bot

Bricks & Chips…
Testing Your Robot

Test the movements of the robot using RCX built-in program #1. The
robot should go forward at quite a fast speed. Next, test it out using
built-in program #4. The robot should move in random directions. It
should be able to turn freely on its caster wheel.

Adding a Light Sensor

With the addition of a light sensor attachment, the Three-in-One Bot will detect
and follow lines on a playing field such as the test pad provided in the RIS 2.0.
Line following is an important task in many competitive challenges, and all
good robots must be able to do it reliably.
The designer of the Three-in-One Bot has created a set of building instruc-
tions that will show you how to add the light sensor to your Three-in-One Bot.
The directions for building an additional light sensor sub-assembly can be found
on the Syngress Solutions Web site at www.syngress.com/solutions.
To check out the line following capabilities of the Three-in-One Bot we
encourage you to visit www.geocities.com/laosoh/robots/linefollow.htm, where
the designer of this robot has posted some of the results and pictures of the
Three-in-One Bot in action.
