1. A balancing ball vehicle comprising:
- a spherical ball having a center and a central axis that passes through the center;
a first driving wheel frictionally engaged with the ball and rotating about a first wheel axis; and
a second driving wheel angularly spaced about the central axis from the first driving wheel, frictionally engaged with the ball, and rotating about a second wheel axis.

Abstract
A balancing ball vehicle includes a spherical ball having a center and a central axis that passes through the center, a first driving wheel frictionally engaged with the ball and rotating about a first wheel axis, and a second driving wheel angularly spaced about the central axis from the first driving wheel, frictionally engaged with the ball, and rotating about a second wheel axis.

10. A balancing ball vehicle comprising:
-
a spherical ball having a center and a central axis that passes through the center; a first driving motor frictionally engaged with the ball and supported for rotation perpendicular to a first radius of the ball; a second driving motor angularly spaced about the central axis from the first driving wheel, frictionally engaged with the ball, and supported for rotation about perpendicular to a second radius of the ball; multiple first bearings mutually angularly spaced about the central axis, each first bearing contacting the ball at first points of contact that define a first plane; and multiple second bearings mutually angularly spaced about the central axis, each multiple second bearings first bearing contacting the ball at second points of contact that define a second plane that passes through the center. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A balancing ball vehicle comprising:
-
a spherical ball having a center and a central axis that passes through the center; a first driving motor frictionally engaged with the ball at a first point of contact, and supported for rotation perpendicular to a first radius of the ball; a second driving motor angularly spaced about the central axis from the first driving motor, frictionally engaged with the ball at a first point of contact, and supported for rotation perpendicular to a second radius of the ball perpendicular to the first radius, the first electric motor driving the ball about the second radius, the second electric motor driving the ball about the first radius; multiple first bearings, each first bearing mutually angularly spaced about the central axis, located above the elevation of the center, and contacting the ball at third points of contact that define a first plane; and multiple second bearings, each second bearing mutually angularly spaced about the central axis, contacting the ball at fourth points of contact that define a second plane that passes through the center. - View Dependent Claims (18, 19, 20)
