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; and
c. a set of compensated actuators disposed intermediate the upper deck frame and the platform and arranged in a predetermined pattern, each compensated actuator of the set of compensated actuators comprising:
i. a base, comprising:
1. a first attachment point configured to be connected to the platform at a first predetermined location with respect to the upper deck frame;
2. a second attachment point configured to be connected to the platform at a second predetermined location with respect to the upper deck frame proximate the outer perimeter;

ii. an electric actuator pivotally connected to the base at a base coupler, the base coupler comprising a first base joint, and pivotally connected to the deck at a first joint; and
iii. a fluid actuator pivotally connected to the base at a second base joint and to the deck frame at a second joint pivotally connected to the first 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 , where the predetermined pattern comprises being disposed evenly and radially outward from proximate a center point of the upper deck frame to the outer perimeter.

4. The compensated motion base of claim 1 , wherein the first joint and the second joint are substantially co-located.
