GOPHER

Gopher is a robot which exhibits the following behaviors:

  1. Wanders tabletop without falling off
  2. Collects three disks, one at time, depositing them at "Home base" (an IR beacon)
  3. Stops at "Home base" when all objects collected

The Gopher utilizes the MTJPRO11A controller board containing the Motorola MC68HC11 due to its small size, low cost, and popularity among the class. The name Gopher comes from the common play-on-words to "go for" things. His sensor suite includes IR beacon detection, IR edge detection, and a Laser / CDS cell object detection circuit.
