Abstract

This paper presents an approach to reduce the energy consumption of industrial robots by optimizing the position of the robot base platform. The approach utilizes a comprehensive energy model for electrical drive systems with DC-bus coupling. The position is optimized for a predefined task in terms of energy consumption and the energy saving potential is analyzed. The results are compared to existing approaches that do not consider the DC-bus energy exchange and it is shown that the utilization of a comprehensive model helps in further improving the energy efficiency. The impact of the base position on the energy consumption is examined by varying the position in a discrete grid. The optimization takes kinematic and dynamic boundaries into account.
