Gravity control device

A gravity control apparatus, comprising:

• a first rotating body that rotates along a first axis as a result of being driven by a first driving device;
• a second rotating body that rotates along a second axis orthogonal to the first axis, within an inside region of the first rotating body, as a result of being driven by a second driving device;
• an accelerometer that is positioned at any position on the second rotating body and detects acceleration;
• and
• a control device that controls driving of the first driving device and the second driving device;
• wherein the control device calculates an acceleration vector from Equation 1 below and controls driving of the first driving device and the second driving device on the basis of acceleration data detected by the accelerometer so that the integral of teh accelaration vector over a prescribed time becomes a prescribed value:
• [Equation 1]
• A=g+rω2 (Equation 1),
• where A, g, r, and ω respectively represent an acceleration vector at an arbitrary point P in the second rotating body, a gravitational acceleration vector at the point P, a distance vector from a point of intersection of the first axis and the second axis to the point P, and an angular velocity vector at the point P.
