The thesis covers the production of a robotic cell for the assembly of patterns constructed of small tiles and in particular the determination of the time of assembly operations for producing of the mentioned patterns. The starting robotic cell concept allready exists, however it is necessary to produce new mechanical components, a new robotic gripper, to program an appropriate robot working cycle and analyze its functioning. Since the field covers handling and assembly as well as robotics, theoretical bases of the mentioned areas are presented in the first part of the paper. Following, a more detailed description of the product structure, which is the basis for the creation of the assembly operations structure and the robot working cycle program is described in detail. The thesis also includes the design and construction of a new buffer for parts and the construction of a robot gripper. The final, more important, part of the thesis presents an analytical calculation of the time of assembly operations and a comparison with the actual measured time of assembly operations.
