Roboty přímo spolupracující s člověkem

Abstract

The dissertation thesis follows up on the cooperation between a robot and a human. This topic has recently been a significantly discussed problem in the field of industrial robotics. There are new opportunities for robotic workplace design where a robot can come into a direct contact with the operator during operation. Such cooperation brings benefits in areas where manual work was used in standard applications and shows new production capabilities. However, this technology also brings risks in regard to the possibility of collision with a moving machine. In the introduction there are analysed the current standards which define basic concepts and ways of human-robot cooperation. Then there follows a thorough research of existing solutions and their evaluation. A survey of available technologies, safety devices and principles of collision detection shows up-to-date possibilities in the development of safe robotic workplaces. The topic of this thesis was specified by ŠKODA AUTO a.s. company as a requirement for an implementation of this technology to the car production process. Based on requirements both for theoretical research and the real workplace development, there has arisen an opportunity for a precise design, realization and profound check of the final solution. The thesis also deals with a pre-design phase of workplace selection, setting requirements and task definition, including the realization of the project and its evaluation. The proposed methodology combines technical standards and experiences from the pilot project development and realization. This workplace is unique in the scope of application of the human-robot cooperation in the real production according to available information. The evaluation method for robotic workplace safety during the whole operation has been proposed in an additional study done at Tohoku University and is described in the last chapter. This method does not monitor exceeding the safety limits only in certain situations but during the whole movement of the operator in the robot’s working range.
