The David series robot was developed in order to bring a low cost, entry level way of getting into the fighting robot ring. The robot made it’s first appearance at the Cumming Robotics Club in North Georgia. It’s been in a bin in my closet for years. Due to some recent interest by some very eager individuals, I have decided to revive the project.
