New technology from the Royal Institute of Technology (KTH) in Stockholm is teaching a household robot a more efficient way to get around a house, for example. The method was recently awarded a prize for the best contribution among 500 others at IROS, one of the world’s largest robot conferences.
Philipp Althaus describes the concept in his dissertation, to be defended on November 21. Robots are making their way into our homes, toy robots and simple household robots. This is a clear trend, and by 2005 the market estimates that more than twice as many household and toy robots will be sold in the world compared to today.
A major problem for a household robot is how to get around in an unknown environment. A chair that has been moved or a person standing in the way can easily confuse a robot. Several earlier attempts have involved programming an enormous amount of map data about the environment: Where are the walls? What does every obstacle look like in detail? How far is it between this thing and that thing? This is not an efficient way to go, since the amount of data grows exponentially with the surface the robot is to navigate. The more data there is, the more the robot has to think, and the slower it moves. Nor is a robot especially good at improvising when unexpected obstacles turn up. Computing power is no guarantee of success.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
