The vision for this project is to create a chair that is convincingly animated to be afraid of people. The chair will run away and turn its back on anyone who tries to sit down. If anyone sits in it, pneumatic pistons mounted on the legs will rock the chair back and forth in an attempt to dislodge the sitter. A big part of this project will be trying to express fear only using the motion.  Ideally the chair would use mechanum wheels so it can move in any direction.
