A see-saw apparatus includes a base, a beam, a first and second carrier platform, at least one actuator, and an actuator control device. The beam, with a first and a second end, pivotally attaches to the base at a fulcrum between the first and second end. The first carrier platform couples to the first end and is configured to receive a wheelchair. The second carrier platform couples to the second end and is configured to receive a wheelchair. The at least one actuator is coupled to the beam and the base, and is configured to cause the beam to pivot between a first and a second position. The first position defines a limit of travel in a first pivotal direction, and the second position defines a limit of travel in a second pivotal direction opposite the first pivotal direction. The actuator control device couples to the at least one actuator.
