The 33-005 Pendulum is a contemporary version of the classic control problem. It is large enough to be convincing, durable enough to survive the hazards of a student laboratory, and open enough for design studies. A twin-arm pendulum pivots freely on a small cart running on an elevated two-rail track. Encoders give the angular position of the pendulum and the linear position of the cart software derives velocity and acceleration for both items. A real-time kernel operating under Windows handles interprocess communication.
