    • Synopsis: Twitch is a 3 servo hexapod (for lack of better classification). Twitch is controlled via two Wixel boards and an Arbotix Commander. The mobility of Twitch far greater than any other approach to a 3-servo walker that I have seen, and makes for a cheap bot that I can let anyone try driving.
