Inherently balanced control stick
First Claim
1. A control apparatus comprising:
- a first mounting member;
an elongate member comprising;
a first elongate portion configured as a first lever arm having a first mass;
a second elongate portion comprising a first feedback assembly having a first interface device, and configured as a second lever arm having a second mass; and
a first axis member between the first elongate portion and the second elongate portion, pivotally mounting the elongate member to the first mounting member and defining a first axis between the first lever arm and the second lever arm; and
a track configured as an arc defined about the first axis wherein the first interface device is configured to travel along the track in response to movement of the second elongate portion partly about the first axis;
wherein the first elongate portion and the second elongate portion are substantially balanced across the first axis, the first mass substantially offsets the second mass across the first axis member, and the mass of the first elongate portion is arranged to create, when exposed to acceleration forces, a first torque about the first axis that substantially neutralizes a second torque created about the first axis when the second elongate portion and the first feedback assembly is exposed to the acceleration forces.
