  • Process for Calibrating the Position of a Multiply Articulated System Such as a Robot
    Publication number: 20110046925
    Abstract: The present invention relates to a method of calibrating the position of a multiply-articulated system, notably a robot. The multiply-articulated system consisting of a chain of N segments interlinked by an articulated link, the calibration minimizing the difference between the measured position Xm of a member linked to the last segment of the chain and its calculated position XC, XC being equal to the product A1.A2 . . . Ai . . . AN.XN, a homogeneous transformation matrix Ai being associated with each segment of order i, this matrix being a function of configuration parameters of the system and of given generalized parameters characterizing the flexibility of the segment, the method comprises: a first step of calculating a flexible model of the system consisting of the matrices A1, A2 . . . Ai . . .
