Dans les entrepôts logistiques, les moyens robotiques sont de plus en plus fréquemment utilisés pour réduire les temps non productifs, déplacer des charges lourdes, limiter les risques d'erreurs pendant les opérations de préparation de commandes (picking, de/palettisation,...), faire des inventaires (drones,...) et améliorer les conditions de travail des opérateurs humains. Bien que l'homme reste incontournable pour les tâches de préparation de commande à cause de son adresse et de son aptitude à s'adapter à des tâches toujours différentes, l'augmentation de la productivité est souvent synonyme d'augmentation de la pénibilité au travail (troubles musculo-squelettiques,...). Les travaux de recherche présentés dans cette thèse sont une contribution à la robotisation des opérations de dé/palettisation pour des colis de taille variable qui exigent une grande polyvalence du système de préhension. La solution innovante que nous proposons consiste à utiliser un torse humanoïde équipé de deux bras manipulateurs munis de préhenseurs adaptés à la saisie d'objets de taille et de masse différentes. La principale contribution porte sur la conception d'une loi de commande hybride Force/Position-Position avec commutations, estimation du glissement de l'objet, prise en compte de la compliance et correction de la force de serrage pendant la manipulation. Cette solution suppose d'assurer la collaboration entre les deux bras manipulateurs et de s'adapter à l'environnement matériel et humain (cobotique). / In logistics warehouses, automation in the sense of robotization is frequently being employed to cut down production times by efficiently managing the processes of picking heavy loads, place, pack and palletize, while reducing the risks and errors to improve the working conditions of human operators along the way. The flexibility of human is fundamental for order preparation owing to adaptive skills for task variation, but at the same time increasing productivity is complemented with fatigue (musculoskeletal disorders). In this context the research presented in this thesis is a contribution in the robotization of palletization operations requiring exceptional versatility of manipulation and gripping. We have proposed an innovative solution of utilizing a humanoid torso equipped with two manipulator arms with adaptive grippers to grasp and hold the objects of variable size and mass. The main contribution of research is the development of a hybrid Force / Position-Position control law with commutation and estimation of the object surface slip, while taking into account the compliance and correction of the clamping force during handling. The execution of the control involves the collaboration of the two arms for coordinated manipulation and adaptation to the material and the human environment (cobotics).

The diploma thesis deals with an orientation mechanism of industrial robots for mounting of pivots and screws into the mounting holes. In the first phase there is a research of inventions mainly realized in the United States Patent and Trademark Office database. Subsequently the conditions of the assembly are solved. On the base of the conditions the functional requirements are described. The diploma thesis includes seven conceptual variants, which are proposed as a 3D design. Using the basical multi-criteria method the best conceptual variant is specified. That is specified due to the accepted criterias. In the next part of the diploma thesis there is a calculation, that comprises this technically and economically most promising conceptual variant. The calculation consists of a statics, a kinematics and a dynamics of the propel, a stenght control of the mechanism and kinematics analysis of the whole mechanism. Results of the calculation are used by the detailed design of orientation mechanism, that also comprises technological production theory and a correct assembly. Economical analysis, which comprises cost of produce of this newly developed automation equipment, is worked up in the conclusion of the diploma thesis. The diploma thesis also comprises drawings. The variant solves a new conception, which can be patented as an utility model.
