The Rotary Inverted Pendulum module attaches to the Rotary Servo Base Unit, expanding the mechatronics and controls topics that can be taught. The pendulum module challenges students to not only model and control a pendulum, but also to learn about hybrid control systems by tuning a swing-up control system. In addition to teaching intermediate control concepts, the Rotary Inverted Pendulum can be used for research in various areas, including fuzzy control.
