Promising approaches for robot accuracy improvements belong to the visual servoing methods. These methods comprise closed-loop control systems, which utilize sensors to guide the robot relative to visible features of a work-piece. However, the known methods show limitations regarding their usability for highly accurate applications or tasks without a(More)
Especially in cases of robot supported process tasks with high accuracy requirements, exactly known geometric relations of the process relevant cell components relative to each other is of significant importance. To establish these relations, several methods are known from the state of the art, belonging to the area of calibration. However, compensating all(More)
Planning of 3D-trajectories for robots can be very time consuming, especially if a defined movement of the work-piece relative to a process-tool is required. Commonly the dynamic attributes of the robot are not considered during the planning. Adjacent process planes, which share the same edges but have different angles of their surface normals, require an(More)
Improving the absolute accuracy of industrial robots is addressed by multiple activities of research institutes and robot manufacturers. Challenging in this context is an accuracy improvement of the robot during the movement. This is due to the necessity of providing time efficient and accurate target and actual state determination modules, an adequate data(More)
