Abstract
A spherical body drive type movement device 10 includes rotary bodies 14, 15, and 16 rotating n number of driving spherical bodies 11, 12, and 13 by being rotationally driven in a state of being in contact from two different directions with each of the driving spherical bodies 11, 12, and 13, and moves on a traveling surface G. The rotary bodies 14, 15, and 16 come into contact with the driving spherical bodies 11, 12, and 13 at positions higher than centers P1, P2, and P3 of the driving spherical bodies 11, 12, and 13 in contact and inside a virtual inverted n-gonal pyramid H or, at positions higher than the centers P1, P2, and P3 of the driving spherical bodies 11, 12, and 13 in contact and on lateral faces α, β, and γ of the virtual inverted n-gonal pyramid H.
