Abstract
In an embodiment, a system includes a frame configured to support a load, a first set of wheels provided on the frame, a second set of wheels provided on the frame, and a controller. The first set of wheels is configured to descend or ascend in response to the controller, and is oriented to move in a first direction. The second set of wheels is configured to descent or ascend in response to the controller, and is oriented to move in a different direction from the first direction. The controller configured to control the descent and ascent of the second set of wheels and the first set of wheels.
Claims20
A system comprising:
- a frame configured to support a load;
- a first set of wheels provided on the frame, wherein the first set of wheels is configured to descend or ascend in response to a mechanical controller, and is oriented to move in a first direction;
- a second set of wheels provided on the frame, wherein the second set of wheels is configured to descend or ascend in response to the controller, and is oriented to move in a different direction from the first direction;
- and
- the controller configured to control descent and ascent of the second set of wheels and the first set of wheels, wherein:
- the controller includes a first controller associated with a first subset of wheels and a second controller associated with a second subset of wheels;
- each of the first controller and the second controller is joined to the frame by at least one joint, the at least one joint providing at least two degrees of freedom;
- and
- the at least one joint is configured to permit the first controller and the second controller to be separately and independently operated.
A method comprising:
- providing a first set of wheels on a frame, wherein the first set of wheels is configured to ascend or descend in response to a mechanical controller and is oriented to move in a first direction;
- and
- providing a second set of wheels on the frame, wherein the second set of wheels is configured to descend or ascend in response to the controller, and is oriented to move in a different direction from the first direction;
- wherein:
- the frame is configured to support a load;
- the controller is configured to control descent and ascent of the second set of wheels and the first set of wheels;
- the controller includes a first controller associated with a first subset of wheels and a second controller associated with a second subset of wheels;
- each of the first controller and the second controller is joined to the frame by at least one joint, the at least one joint providing at least two degrees of freedom;
- and
- the at least one joint is configured to permit the first controller and the second controller to be separately and independently operated.
