Smoothly moving industrial robots save energy

04.06.2014

Siemens wants to further reduce the power consumption of manufacturing robots in the automotive industry.

One approach to this problems deals with movement patterns that require less acceleration energy, as was reported in the latest issue of the magazine "Pictures of the Future".

Working with Volkswagen and Fraunhofer Gesell­schaft as part of the Green Carbody Technologies (InnoCaT) innovation alliance, Siemens studied the motion sequences of manufacturing robots. The partners developed a simulation model that calculates the best trajectories for robots from the standpoint of energy efficiency.

Tests have shown that this approach can reduce energy consumption by up to half. Goal is to develop a software program that can be used to reprogram existing manufacturing robots to operate in a more energy-efficient manner, without making changes to the production process.

Manufacturing robots make an automotive factory fast and efficient, but they also consume large quantities of electricity. Particularly in body shell production, where numerous robots are deployed, they account for more than half of the total energy consumed. One approach to saving energy involves the control system.

Today's robots are extremely jerky in their movements. They move their arms along straight lines and brake abruptly at every change of direction before turning and accelerating again. This costs a great deal of drive energy and stresses the mechanics.

In the laboratory, the engineers analyzed a robot's energy consumption in different work steps. They wanted to know the extent to which changes of direction influence power consumption, and determine the parameters that result in the best movement patterns in terms of energy consumption.

This analysis yielded new algorithms for a simulation model that calculates optimal motion trajectories. Based on the lab tests, they found a savings potential of between 10 and 50 percent when the robot's arms move evenly along curved paths. Furthermore, the mechanical parts are placed under less stress, resulting in lower maintenance costs and fewer downtimes.

In the automotive industry it is extremely important that numerous manufacturing robots, which often hand over work to one another in a matter of seconds, operate together smoothly. Long tests under realistic conditions showed that optimized movement patterns can lower energy consumption by up to 50 percent, even with the same cycle times.

A software module that automatically programs a robot's power consumption for a given work process, while also accommodating the interplay with adjacent machines, is under test. Automation is important: It is the only economically feasible way to reprogram thousands of manufacturing robots in a single factory.

Siemens plans to integrate such a module into its Tecnomatix manufacturing software. This will allow existing robots to be easily and safely reprogrammed to consume less energy without requiring new investments in hardware.

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
