Seesaw
Electromechanical Control
The Seesaw module is ideal to introduce intermediate control concepts, involving dynamics and control similar to the inverted pendulum experiment. You can use it to demonstrate real-world control challenges related, for example, to the roll control in aircraft.

Product Details
The Seesaw module consists of two long arms hinged onto a support fulcrum. The system is composed of precisely machined polycarbonate with a durable matte finish. The Seesaw rotates about the pivot axis on an instrumented fulcrum. The rotation axis is coupled to an encoder through a pinion-and-anti-backlash-gear system and is used to measure the Seesaw tilt angle.
