Weeding is a major problem for ecological growers since it is both expensive and time-consuming. New robot technology may have the solution. In a new dissertation, Björn Åstrand, from Halmstad University in Sweden, presents how weeds can be removed mechanically -with the fully automated robot Lukas.
In ecological cultivation, weeding is performed manually, entailing not only economic burdens for many growers but also logistic ones -it’s hard to find people willing to do this work, and many growers therefore have to limit their production.
“For an ecological grower of beets, weeding can cost about SEK 10,000 per hectare. With robot technology we estimate that these costs can be cut in half. In the long term this technology would also mean major environmental benefits by ultimately replacing chemical herbicides in traditional cultivation,” says Björn Åstrand, who works at the School of Information Science, Computer and Electrical Engineering at Halmstad University. He is formally a doctoral candidate at Chalmers University of Technology in Göteborg.

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...
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...
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...
