Abstract [en]
The rise in energy consumption and the associated costs instigate financial concerns among industrialenergy consumers. For industrial processes addressing heating and cooling as well as materialtransformation, a wide range of energy efficiency measures have been developed and successfullyimplemented. In contrast to that, most robot-based operations such as pick-and-place motions orassembly tasks still use inefficient standard concepts causing high-energy consumption and high-energycosts. Thanks to a rather low payload-to-weight ratio of new robot designs, such as parallel kinematic orhybrid robot manipulators, a high potential for energy savings is expected. This article identifies potentialsfor energy saving concerning industrial consumers by assessing three different robot concepts. Based on aliterature review, two existing designs for robots – the conventional serial robot and the parallel kinematicrobot are analysed and compared with respect to the energy utilised during a typical item placementtask. Afterwards, the concept of PARAGRIP, a hybrid of the two presented robot designs is introducedand examined based on simulation regarding its energy consumption. The final results demonstratesignificantly different energy consumptions between the robot concepts, identifying potential savings ofabout 40% in a selected industrial application scenario.
