The "Swing Thing" is this group's interpretation of a fantasy car.  It uses two arms, with clamp-like hands, to climb along a raised bar.  The idea came out of a brainstorming session that began with the idea of a robot that could swing on "monkey bars" similar to those on a playground.  After reconsidering, due to the need for a third rail that would run above the bars, the group decided to go for a machine that would swing along one bar.  The swinging motion has been a challenge due to the gravity-defying motion of the robot.  However, with the correct servo motors in place the group assured me of the plausibility of their success.
