SERVO – April 2008 – Reviving an Androbot BOB # 3
The last couple articles covered using a lot of leftover parts to revive an early Androbot BOB prototype. He was missing all of his brains and had been sitting for years as an empty shell. Although I would have preferred to find the original electronics, I decided that I should at least use some extra parts from past projects to get BOB rolling again. All of the new electronics just plug in and bolt on so that no alterations are done to the original shell. This article covers adding an extra co-processor to off load some of the tasks so the main controller can focus on the higher level thinking. The co-processor used in this project is a Parallax SX48 programmed in SX/B. It controls the head movement, lighting on the body, and holds the speech chip.
