Abstract

A compensated actuator, in various embodiments, comprises a base and an electric actuator and a fluid actuator interconnected to cooperatively allow for movement of an upper deck frame to which one or more compensated actuators are connected with or without using a pivoting connector. When so connected, a predetermined set of compensated actuators are connected to the upper deck frame and a platform intermediate the upper deck frame and the platform in a predetermined pattern and linear forces from the electric actuator and fluid actuator combined to impart rotation to an output attachment point.

First claim

What is claimed is:

1. A compensated motion base, comprising:
a. an upper deck frame comprising a predetermined outer perimeter;
b. a platform;
c. a pivoting connector, comprising:
i. an output attachment point configured to be pivotally attached to a payload-bearing deck;
ii. a first connector joint; and
iii. a second connector joint;

d. a set of compensated actuators disposed intermediate the upper deck frame and the platform, the set of compensated actuators arranged in a predetermined pattern, each compensated actuator of the set of compensated actuators comprising
a base, comprising an upper surface, a lower surface, and a longitudinal axis, the base further comprising:
i. a first attachment point disposed along the longitudinal axis at which the base may be attached to a platform at a first platform location;
ii. a second attachment point disposed at a distance along the longitudinal axis away from the first attachment point to at which the base may be attached to the platform at a predetermined second platform location proximate an outer perimeter of the platform;
iii. a linear actuator joint disposed at a predetermined position about the upper surface along the longitudinal axis intermediate the first attachment point and the second attachment point;
iv. a fluid actuator joint disposed about the upper surface at a predetermined position proximate the linear actuation joint; and
v. a connector joint disposed about the upper surface opposite the linear actuator joint, the connector joint configured to accept a pivoting connector;

e. an electric actuator, comprising:
i. a first joint configured to be cooperatively and pivotally connected to the pivoting connector at the first joint and the first connector joint; and
ii. a first base joint configured to be cooperatively and pivotally connected to the base at the linear actuator joint; and

f. a fluid actuator, configured to be cooperatively connected to the electric actuator, the fluid actuator comprising:
i. a second joint pivotally connected to the pivoting connector at the second connector joint; and
ii. a second base joint configured to be pivotally connected to the base at the fluid actuator joint.

2. The compensated motion base of claim 1 , further comprising a set of fluid supply tanks, each fluid supply tank of the set of fluid supply tanks operatively in fluid communication with a corresponding fluid actuator.

3. The compensated motion base of claim 1 , wherein:
a. the upper deck frame comprises a triangular outer perimeter;
b. the set of compensated actuators comprises three compensated actuators, each output attachment point of the three compensated actuators configured to be pivotally attached to the upper deck frame proximate a triangular junction point on the outer perimeter; and
c. the corresponding set of fluid supply tanks comprises three fluid supply tanks, each fluid supply tank in fluid communication with a corresponding compensated actuator of the three compensated actuators.

4. The compensated motion base of claim 3 , wherein the set of compensated actuators is arranged evenly and radially outward from proximate a center point of the upper deck frame to a predetermined triangular junction point on the outer perimeter.

5. The compensated motion base of claim 1 , wherein:
a. the compensated motion base further comprises a pitch or roll platform; and
b. a compensated actuator of the set of compensated actuators is operatively connected to the pitch or roll platform.

6. The compensated motion base of claim 1 , wherein the pivoting connector further comprises:
a. a pivot junction;
b. a first extension extending away from the pivot junction and comprising the output attachment point, the first extension configured to be pivotally connected to the upper deck frame; and
c. a second extension extending away from the pivot junction at a predetermined offset from the first extension and comprising the first connector joint, the second extension configured to be connected to an electric actuator of the group of compensated actuators at the first joint and the first connector joint; and
d. a hinge joint defined at a meeting junction of the first extension and the second extension, the hinge joint comprising the second connector joint.

7. The compensated motion base of claim 1 , wherein the pivoting connector further comprises:
a. a support bracket comprising a pivot junction;
b. a support arm connected to the support bracket, the support arm pivotally connected to the first extension at a support arm pivot connector; and
c. a pivot pivotally connected to the support bracket at the pivot junction and configured to be connected to the deck at a support connector.
