The Rotary Flexible Link module is designed to help students perform flexible link control experiments. The module is designed to be mounted on the Rotary Servo Base Unit. This experiment is ideal for the study of vibration analysis and resonance and allows to mimic real-life control problems encountered in large, lightweight structures that exhibit flexibilities and require feedback control for improved performance. The experiment is also useful when modeling a flexible link on a robot or spacecraft.
Rotary Flexible Link
The Rotary Flexible Link consists of a strain gage which is held at the clamped end of a thin stainless steel flexible link. The DC motor on the Rotary Servo Base Unit is used to rotate the flexible link from one end in the horizontal plane. The motor end of the link is instrumented with a strain gage that can detect the deflection of the tip. The strain gage outputs an analog signal proportional to the deflection of the link. In this experiment, students learn to find the stiffness experimentally, and use Lagrange to develop the system model. This is then used to develop a feedback control using a linear-quadratic regulator, where the tip of a beam tracks a desired command while minimizing link deflection.

Magnetic Levitation
The force between electromagnet and ball is highly nonlinear. Further, the electromagnet itself has its own dynamics that must be compensated for. The challenging dynamics of the system make it perfect for teaching modeling, linearization, current control, position control, and using multiple loops (i.e. cascade control). It could also be used to test and implement more advanced control strategies, such as multi-variable, gain scheduling, and nonlinear control.

QLabs Virtual Rotary Servo
Same as the physical Rotary Servo Base Unit, the virtual system features a DC motor that drives a smaller pinion gear. This gear is fixed to a larger middle gear that rotates on the load shaft. The position of the load shaft is measured using a high-resolution optical encoder or a potentiometer.
2 DOF Robot
The 2 DOF Robot module is connected to two Rotary Servo Base Units, which are mounted at a fixed distance. Two servomotors on the Rotary Servo Base Units are mounted at a fixed distance and control a 4-bar linkage system: two powered arms coupled through two non-powered arms. The system is planar and has two actuated and three unactuated revolute joints.
The goal of the 2 DOF Robot experiment is to manipulate the X-Y position of a four-bar linkage end effector. Such a system is similar to the kinematic problems encountered in the control of other parallel mechanisms that have singularities.
