Linear Flexible Inverted Pendulum
The Linear Flexible Inverted Pendulum module augments the classic inverted pendulum challenge by including a flexible link that requires balancing. The Linear Flexible Inverted Pendulum module attaches to the Linear Servo Base Unit and has both a rigid long rod and a flexible link. The goal is to balance both pendulums using the base angle measurement as well the deflection angle of the flexible link.
Product Details
The linear flexible inverted pendulum challenges students to gain advanced modeling and control experience by controlling both the damping of a flexible link, and an unstable inverted pendulum.
