His dissertation titled "On Methods for Assistive Mobile Robots" presents a new navigation method that finds open and free areas where a vehicle can navigate. These free, open areas are used to create a map that can be used for navigation. The research has resulted in a new type of wheelchair prototype called MICA-Mobile Internet Connected Assistant.
“MICA is connected to the Internet and can be remote controlled or driven manually, but can also navigate on its own. The new navigation method is used to find possible routes for the wheelchair, past various obstacles, for instance. A distance-metering sensor is used to discover the surfaces that are available to the wheelchair, and the technology can also be used to ensure that the wheelchair is being used in a safe manner,” says Sven Rönnbäck.
One prospective user group would be severely handicapped individuals who would otherwise find it difficult to steer a wheelchair. Using a computer and a mouse controlled by the head, they can steer the wheelchair through head movements alone, which would obviously open new possibilities for people who have suffered spinal injuries, for example, and substantially lost control of their arms and legs.
“With the new navigation system, users can use their head to give commands to the wheelchair. Examples of commands are ‘take the next possible left,’ ‘next possible right,’ ‘follow the wall,’ ‘turn right/left,’ ‘go straight ahead,’ ‘go through the doorway,’ etc.”
Ultimately this new technology can be used to guide the blind and sight impaired as a complement to the cane. Since the technology also creates a map, it can also assist people who suffer from dementia and impaired memory. The technology thus provides the user with both enhanced freedom and reduced dependency on relatives and personal assistants.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
