I've been trying to get motivated for my son's Boy Scouts troop. The Scouts have a new merit badge offering in "Robotics" and I'm the unofficial merit badge councilor. There is a ton of interest within our troop (we have one of the largest troops in the country). So, I'd be interested in what other are doing. My goal is to develop a robot design that the boys could build at i3. A laser cut frame, a couple of cheap RC servo motors modified for continuous rotation, and a intro micro board and we're in business.
Here is a link to some stuff I've been working on.
