Abstract:
An actuator system for moving a platform, comprising:a motor which rotates a rotational element; a transmission system which engages the motor and selectively engages the platform, the transmission system comprising a first rail connected to the rotational element so as to move in a first direction according to the rotation of the rotational element, and a second rail connected to the rotational element so as to move in a second direction according to the rotation of the rotational element; a first lock which engages the transmission system such that the transmission system moves the platform according to a rotation of the rotational element; and a second lock which engages the transmission system such that the transmission system moves the platform moves according to the rotation of the rotational element, wherein: when the first lock engages the transmission system and the second lock does not engage the transmission system, the first lock connects the first rail and the platform such that the platform moves with the first rail in the first direction according to the rotation of the rotational element, and when the first lock does not engage the transmission system and the second lock engages the transmission system, the second lock connects the second rail and the platform such that the platform moves with the second rail in the second direction according to the rotation of the rotational element.
