This diploma thesis discusses a proposal of "a manipulator for casting of cylinders". This manipulator is a part of a brushing machine complex, which is not a part of my diploma thesis. With the aid of the manipulator it is possible to exchange cylinders of brushing machines. The computational section includes calculations of traversing mechanism, stroke mechanism and electric drive. Furthermore, a calculation of the main constructional elements is solved. One part of the diploma thesis is, indeed, dedicated to the partial graphic documentation, which is in the range of the assembly reports of the manipulator main parts.
