Four calibration steps, modeling, measurement, identification, and implementation are investigated. First a formula is proposed which allows to calculate the number of independent kinematic parameters required for a complete model of a parallel structure. Accuracy can be improved either by precise manufacturing and assembly or by calibration of each individual robot using a kinematic model which takes geometric deviations into account. For the first time al1 the solutions of the direct problem for the delta robot were found by means of an algorithm introduced by husty. Fast solutions of the direct and inverse problems had to be found. His laboratory is awarded the grand prix de linnovation in monaco for new robot technologies Buy now Reymond Clavel Thesis
For the first time al1 the solutions of the direct problem for the delta robot were found by means of an algorithm introduced by husty. The main objective of this thesis is the accuracy improvement of parallel robots. Conception of robots with high speed, high dynamics and ultra high precision. Each of his three different submitted projects received the swiss technology award. To substantiate the theoretical tools proposed in this thesis two examples of parallel structures are chosen. Reymond clavels research successes in 1996 project winner of the technologiestandort schweiz competition and abb sonderpreis for the best robotics project. For parameter identification different methods were tested by simulation Reymond Clavel Thesis Buy now
His present research topics are parallel robotics, high speed and high precision robotics, medical and applications, surgical instrumentation and precision mechanisms. One of them is the delta robot with three translational degrees of freedom whereas the second example is a novel structure called argos having three rotational degrees of freedom. Then a systematic parameterization is introduced and applied to derive four calibration models, two for each example. Calibration based on the implicit model is proposed as a standard method to calibrate parallel robots. Accuracy can be improved either by precise manufacturing and assembly or by calibration of each individual robot using a kinematic model which takes geometric deviations into account Buy Reymond Clavel Thesis at a discount

Investigations were restricted to static errors due to geometric deviations assuming rigid bodies. Using these calibration methods for the two robots, argos and delta, between a three to a twelvefold improvement of accuracy was achieved and experimentally verified. Project winner of the swiss technology award competition with further the sonderpreis 2005 from the vontobel foundation in the field of inventing the future. In addition a fast numeric algorithm for the deltas direct problem is proposed. Two measurement devices are described which were built to determine the position and orientation (pose) of the endeffectors of the two robots. For experimental verification a mockup was built for each of the two structures Buy Reymond Clavel Thesis Online at a discount
