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.
