Abstract
A device includes a frame having a plurality of rails, each rail including a slider. A first rail support member is connected to a first end of the plurality of rails, and a second rail support member is connected to a second end of the plurality of rails. The second end is opposite the first end. A plurality of arms is connected to the sliders. Each arm includes a ball joint at one end connected to one of the sliders. Each arm includes another end, opposite the one end, connected to a platform via a hinge joint. The platform is configured to roll and pitch via changing positions of the sliders along the plurality of rails.
Claims20
A device comprising:
- a frame comprising:
- a plurality of rails, each rail including a slider;
- a first rail support member connected to a first end of the plurality of rails;
- and
- a second rail support member connected to a second end of the plurality of rails, wherein the second end is opposite the first end;
- and
- a plurality of arms, wherein each arm includes a ball joint at one end connected to one of the sliders, and wherein each arm includes another end opposite the one end and connected to a platform via a hinge joint,
- wherein the platform is configured to roll and pitch via changing positions of the sliders along the plurality of rails.
A method comprising:
- providing a device including a frame having a plurality of rails, each rail including a slider;
- and a plurality of arms connected to the sliders via ball joints at one end and connected to a platform via hinge joints at another end opposite the one end;
- actuating the sliders along the plurality of rails via a plurality of motors;
- and
- adjusting roll and pitch of the platform via changing positions of the sliders along the plurality of rails.
A method comprising:
- providing a device including a frame having a plurality of rails, each rail including a slider;
- and a plurality of arms connected to the sliders via ball joints at one end and connected to a platform via hinge joints at another end opposite the one end;
- actuating the sliders along the plurality of rails via a plurality of motors;
- adjusting roll and pitch of the platform via changing positions of the sliders along the plurality of rails;
- controlling heave of the platform by concurrently actuating the sliders in a same direction;
- and
- counterbalancing the weight of the sliders via a counterweight disposed on each rail of the plurality of rails on a side opposite the slider and configured to move in an opposite direction from the slider when it is actuated along the rail.
