Qube-Servo 3

The quickest path to practical controls

Control Systems & Dynamics Robotics & Mechatronics Electromechanical Control Manipulator Robotics Mechatronics

The Qube Servo 3 is the fastest and most efficient way to bring modern, hands-on learning experiences into your Control Systems course. The system is equipped with a high-quality direct-drive brushed DC motor, two encoders, an internal data acquisition system, and an amplifier. Connect with USB to a Windows PC using MATLAB Simulink or Python.

Qube Servo 3 is a part of the Control Systems & Dynamics Lab Collection – Introduction to Controls Teaching Lab.

Info Sheet

Qube-Servo 3 comes with a quick-connect inertia disk and an inverted pendulum module. You can also design and 3D print your own module to expand the scope of the experiment or create an engaging student project. Take advantage of the comprehensive ABET-aligned course material for MATLAB® Simulink®, or design and validate your own controllers. With additional language support in Python and C/C++, new features include the ability to disable deadband compensation to directly model and control the DC motor.

Safe: Built-in motor stall and thermal protection
