Multi-rotor apparatus and method for motion sculpting
First Claim
1. A muscle training apparatus for determining characteristics of a movement of a shaft of an implement by a person during performance of a useful or recreational function, the muscle training apparatus comprising:
- a support structure comprising a plurality of arms extending outwardly from a central portion of the support structure, each of the plurality of arms having a proximal end and a distal end, the plurality of arms including a first arm and a second arm disposed to an opposite side of the central portion from the first arm;
an attachment mechanism for reversibly attaching the central portion of the support structure to the shaft of the implement such that the proximal ends of the arms are disposed adjacent the shaft;
a first sensor disposed adjacent the distal end of the first arm, the first sensor for generating a first sensor signal indicative of a plurality of first positions and first directions of travel of the distal end of the first arm during the movement;
a second sensor disposed adjacent the distal end of the second arm, the second sensor for generating a second sensor signal indicative of a plurality of second positions and second directions of travel of the distal end of the second arm during the movement,where the first and second positions and the first and second directions of travel of the first sensor and the second sensor at any particular point in the movement define an individual average shaft velocity vector substantially coinciding with the direction of travel of the shaft, and an individual shaft displacement vector aligned with the first position and the second position at the particular point; and
a processor for calculating a plurality of individual average shaft velocity vectors, a plurality of individual shaft displacement vectors, a plurality of individual normal vectors, and a plurality of corresponding individual implement shaft planes based on the first and second sensor signals, wherein at any particular point in the movement an individual implement shaft plane substantially coincides with a corresponding individual average shaft velocity vector and an individual shaft displacement vector at the particular point and is perpendicular to an individual normal vector at the particular point.

Abstract
A reversibly attachable muscle trainer includes a multi-arm structure with motion sensors and force generators for exercising opposing muscles of a person moving an implement so as to maintain an ideal movement. When attached to the implement, the muscle trainer trains the opposing muscles to consistently move the implement in an ideal way. While the person moves the implement with the muscle trainer attached, a processor receives signals from the motion sensors and determines differences between the actual implement motion and an ideal implement motion. The difference indicates a dominating force direction in which the dominating muscles urge the implement. The processor activates the force generators to apply external forces to the implement to urge the implement in various types of training force directions.
