Rotary Double Inverted Pendulum
Take the classic inverted pendulum challenge to the next level
Electromechanical Control
The Rotary Double Inverted Pendulum module is ideal to introduce intermediate and advanced control concepts, taking the classic single inverted pendulum challenge to the next level of complexity. You can use it to demonstrate real-world control challenges related, for example, to takeoff stabilization of a multi-stage rocket. The Rotary Double Inverted Pendulum module attaches to the Rotary Servo Base Unit.

Product Details
The Double Inverted Pendulum module is composed of a rotary arm that attaches to the Rotary Servo Base Unit, a short 7-inch bottom blue rod, an encoder hinge, and the top 12-inch blue rod. The balance control computes a voltage based on the angle measurements from the encoders. This control voltage signal is amplified and applied to the Servo motor. The rotary arm moves accordingly to balance the two links and the process repeats itself.
- Double pendulum comprised of a 7-inch aluminum link connected to a 12-inch link
- Double Inverted Pendulum module easily attaches to the Rotary Servo Base Unit
