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 aircrafts.
The Seesaw module is used paired with the Linear Servo Base Unit (IP02). With this setup students learn how to:
In addition to teaching intermediate control concepts, Seesaw can be used for research in various areas, including optimal and intelligent control.
Two Seesaw modules can be coupled together using the supplied Seesaw with Pendulum attachment to implement the Multiple-Input Multiple-Output (MIMO) Seesaw Pendulum experiment. In this experiment, one linear servo cart is used to balance both Seesaw modules while the other linear servo cart balances an inverted pendulum.
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.
A powered cart (Linear Servo Base Unit) is mounted on the seesaw to travel freely along the length of the seesaw. The solid aluminum cart is driven by a rack and pinion mechanism using a 6V DC motor, ensuring consistent and continuous traction. The cart slides along a stainless steel shaft using linear bearings. The cart position is measured using a sensor coupled to the rack via an additional pinion.
The Seesaw and Seesaw Pendulum systems come with Quanser-developed courseware. The Laboratory Guide, together with quick start resources, a comprehensive User Manual, pre-designed controllers and a system model allow you to get your lab running faster, saving months of time typically required to develop lab materials.
Topics included in the Quanser-developed courseware:
To set up your Seesaw workstation, you need additional components. Quanser engineers recommend:
¹ alternatively, you can use Q8-USB, QPIDe or any equivalent NI DAQ device supported by QUARC
² NI cRIO-9074, or NI cRIO-9024 with cRIO-9113 or cRIO-9114 chassis
³ NI DAQ device must be supported by Quanser RCP toolkit. Alternatively, you can use Quanser Q2-USB, Q8-USB, or QPIDe
