METHOD AND SYSTEM FOR PRECISION ERROR COMPENSATION OF A HEXAPODE

摘要

- Method and system for precision error compensation of a hexapod. - The precision error compensation method of a hexapod (2), said hexapod (2) having a base (3), an actuating assembly (4) provided with six cylinders (5) linear translation, a control unit (6) and a movable carriage (7) having a platform (8) connected via the actuating assembly (4) to the base (3), comprises a measuring step for determining geometry and position errors on the hexapod (2), the measuring step comprising sub-steps for determining position errors of the pivot centers on the carriage (7) and on the base (3), for determining length errors of the cylinders (5) and for measuring positioning errors of the jacks (5) on their stroke, the compensation method also comprising a step for calculating, from the measurements made, error compensation values and a step for applying these error compensation values to the control unit (6) of the hexapod (2), at a later use of the latter.
