    Seesaw

    Challenge:
    Design a control system to balance a seesaw using a sliding powered mass.

     

    Description:
    A rotating seesaw is mounted on an instrumented fulcrum. A powered cart 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 goal is to design a controller that maintains the seesaw balance by driving the cart back and forth along the seesaw. The system is supplied with a state feedback controller. You may design any other controller you wish.
