A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

A power transmission unit of a drive mechanism has a link mechanism on both sides of a base portion. The link mechanism has a first link member having a base end portion provided to the base portion to be rotated about a third rotational axis, a second link member having a base end portion connecting the first link member's distal end portion to be rotated about a fourth rotational axis, and a third link member which is provided to a driven body to be rotated about a fifth rotational axis and to which the second link member's distal end portion is provided to be rotated about a sixth rotational axis orthogonal to the fifth rotational axis. A desired operation angle range of two degrees of freedom in a driven body can be ensured with a compact configuration while suppressing deflection of a structure to which the driven body is mounted.

A motion control system for controlling an image projected from an underwater projection system in a water feature includes a chassis, a mirror support coupled to the chassis, a mirror member on the mirror support, a first drive member, and a second drive member. The mirror member is configured to reflect the image projected from the underwater projection system in the water feature. The first drive member is coupled to the chassis and configured to rotate the mirror support relative to the chassis about a first axis to move the reflected image in the water feature. The second drive member is coupled to the chassis and a fixed mount and is configured to rotate the chassis and the mirror support about a second axis to move the reflected image in the water feature.
