First of all, this paper presents how this robot is developed with the goal of reaching very high speed. Indeed, it is an evolution of Delta, H4 and I4 robots architectures: it keeps their advantages while overcoming their drawbacks. Experimentations done with the prototype prove that the robot is able to reach very high accelerations (15 G) and to perform an Adept cycle in 0.25 s. In order to improve its dynamic accuracy, a dynamic control could be necessary. Thus, this paper presents the dynamic modeling of the manipulator using a simplified Newton-Euler approach. The originality of this computation is to model the traveling as two separated parts and to determine the dynamic effects applied on each of them. Finally, since a dynamic control requires a good evaluation of dynamic parameters, an experimental dynamic identification is presented.6enginfo:eu-repo/semantics/restrictedAccessconference output10.1109/IROS.2006.282533Articulated traveling plateDynamic identificationDynamic modelingPKMSchoenflies motionControl and Systems EngineeringSoftwareComputer Vision and Pattern RecognitionComputer Science Applicationshttp://www.scopus.com/inward/record.url?scp=34250656653&partnerID=8YFLogxK
