<p>1. A device for correction of the mechanical imperfections shown by the deviations in movement of the wheels of a moving body having two independent driven wheels (1, 2) driven each by a corresponding stepping-motor and mounted about one and the same axis (3) and effecting various movements ordered by a programming microprocessor, characterized in that a corrector circuit is connected to the said microprocessor in order to indicate to the latter a corrector number which modifies the number of steps carried out by the wheels with respect to the number of steps ordered by the programming in compensation of the deviations due to the mechanical imperfections, the said corrector circuit comprising a means of introduction of a predetermined corrector number of steps into each quantity q of steps to be carried out by each motor, having 5 bistable electrical contacts each having in a first state the signification 0 and in a second state one of the significations 1 - 2 - 4 - 8 - 16 respectively, with a per-unit corrective capacity of 0,125 degrees of rotation of the motor.</p> |
