The controller I use for Merlin is a BotBoard designed by Marvin Green. So Merlin now has two whiskers. I am planning to add two more photo resistors, and a LED for light, to the bottom of Merlin so that he can also function as a line tracker, allowing him to follow a black line drawn on white paper. Merlin does not have any arms or grabbers. Merlin stands about three inches tall.
Merlin is five inches wide.
Merlin is about five and one half inches long. The second power supply consists of four AA batteries for the two servos. I was fascinated with this part of the video, I watched it over and over again always finding something I had not noticed before or trying to figure out how each part of the legs worked and how I could duplicate it. I even built a mock leg to better understand the mechanics of the legs and how the robot walked. This was a over a year ago around April '97.
