Abstract
This invention relates to a servo system for operating an exoskeleton adapted to encircle an object of interest and for supplying a force thereon. A servomotor is coupled to a power source and operates the position of the exoskeleton and thus the force exerted by the exoskeleton on the object of interest. A measuring unit measures a raw driving current signal Isupplied by the power source to drive the servomotor. A low pass filter applies a low pass frequency filtering on the measured a filtered current signal I. A processing unit determines an actuated current signal Ibased on the servomotor setting parameters, where Iindicates the contribution to Ifrom the servomotor when operating the position of the exoskeleton. The processing unit also determines a driving force current signal Iindicating the force exerted by the exoskeleton on the object of interest, where Iis proportional to the difference between Iand I.
