Abstract
Abstract Random motion mechanisms having at least one driving element that is operated at randomly varying speeds. One such mechanism is a self-propelled vehicle which has at least one randomly operated driving wheel. The vehicle desirably has a second randomly operated driving wheel, which is parallel with the first, and at least a third supporting element which can take the form of a wheel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
49 words
A random motion mechanism comprising at least one driving element in the form of a drive wheel, a random signal generator for generating a randomly varying set of signals, and means responsive to the signals from said random signal generator for operating said drive wheel with randomly varying speeds.
Claim 2
Dependent Claim
49 words
A random motion mechanism comprising at least one driving element in the form of a drive wheel, a random signal generator for generating a randomly varying set of signals, and means responsive to the signals from said random signal generator for operating said drive wheel with randomly varying speeds.
Claim 3
Dependent Claim
32 words
A mechanism as described in claim 1 in the form of a self-propelled randomly movable vehicle wherein the vehicle includes a second wheel in parallel with the first wheel and a support.
Claim 4
Dependent Claim
29 words
A vehicle according to claim 2 further including comparator means for predetermining the average duration of the lapse of time during which the driving element adopts a predetermined speed.
Claim 5
Dependent Claim
21 words
A vehicle according to claim 3 further including control module means for determining the average dispersion of said lapse of time.
Claim 6
Dependent Claim
20 words
A vehicle according to claim 2 wherein there are two driving wheels which propel the vehicle along a straight trajectory.
Claim 7
Dependent Claim
26 words
A vehicle according to claim 2 wherein there are two driving wheels which operate to produce rotation of the vehicle in place about a vertical axis.
Claim 8
Dependent Claim
25 words
A vehicle according to claim 2 wherein there are two driving wheels which are driven to produce a null speed corresponding to a complete stop.
Claim 9
Dependent Claim
25 words
A vehicle according to claim 2 wherein there are two driving wheels which operate at different speeds having a constant ratio providing a circular trajectory.
Claim 10
Dependent Claim
83 words
A vehicle according to claim 2 wherein there are two driving wheels which are driven to propell the vehicle along one of a plurality of trajectories corresponding to the following: a straight trajectory where the speeds of the driving wheels are equal; a pivoting in place where the driving wheels rotate at the same speed in opposite directions; a complete stop where the driving wheels are stopped; and a circular trajectory where the driving wheels rotate in the same direction at different speeds.
Claim 11
Dependent Claim
18 words
A vehicle according to claim 2 wherein there are two driving wheels each associated with a distinct motor.
Claim 12
Dependent Claim
20 words
A vehicle according to claim 2 wherein the random signal generator provides a plurality of commuted and independent binary outputs.
Claim 13
Dependent Claim
19 words
A mechanism according to claim 1 wherein the driving element is commanded by electrical signals which have random variations.
Claim 14
Dependent Claim
19 words
A mechanism according to claim 1 wherein the driving element is commanded by a frequency signal with chance variations.
Claim 15
Dependent Claim
21 words
A random motion mechanism according to claim 1 further including a second wheel which is also operated with randomly varying speeds.
