The purpose of our final project was to create an unstable system that would allow us to investigate classical control design methods by controlling the system using a microcomputer.
This was accomplished by creating a teeter-totter that pivoted around a central fulcrum and was controlled by a servo. The beam acted as a track for a ping pong ball to roll on, with the goal of balancing the ping pong ball in the center of the beam.
