Smooth-moving robots cut energy consumption

With their precise mechanical movements, robots seem like the most efficient of workers, but they can actually waste a good deal of energy. Chalmers University of Technology is developing a new optimization tool that acts like an efficiency expert for industrial robots by smoothing their movements to reduce their energy consumption by as much as 40 percent.Read More

Mind-controlled mechatronic prosthetics now a reality

Robotic prostheses have advanced greatly in the past decade, in terms of both cost and capability. Unfortunately, the standard electrode-over-skin method of control makes many of them unreliable and restricts their functionality, meaning that a number of recipients of these devices commonly reject them as a result. However, a Swedish man has recently celebrated a milestone in robotic prostheses by taking advantage of an osseointegrated (bone-anchored), thought-controlled, implant system in his daily life for more than a year and a half.Read More

AstaZero road safety testing facility opens in Sweden

It seems like hardly a week goes by without our hearing about another automated safety feature for cars. Such technologies include systems that detect when drivers are getting tired, that allow multiple cars to safely travel together in speed-controlled "convoys," or that warn drivers when they're drifting out of their lane. Now, in order to help foster the development of more such concepts, a new Swedish test-track facility has begun operations. Read More

Augmented reality treatment alleviates phantom limb pain

Studies have shown that a large percentage of amputees feel pain in their missing limbs. This condition, known as phantom limb pain (PLP), is caused by the part of brain responsible for a limb's movement becoming idle once that limb is lost. The ailment has so far proven difficult to treat, but a new study suggests therapy involving augmented reality and gaming could stimulate these unused areas of the brain, resulting in a significant reduction in discomfort.Read More

Discovery shines a light on potential cure for Alzheimer's and Parkinson's

It is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.Read More

Graphene gets even cooler

For a two-dimensional material, graphene is certainly punching above its weight in terms of potential applications. Already set to enable faster, stronger and foldable electronic devices, researchers claim that the single layer lattice of carbon atoms can also help keep electronic components up to 25 percent cooler, giving it the potential to significantly extend the working life of computers and other electronic devices.Read More

Electrodes for prosthetic arm permanently implanted into patient for first time

It took some time, but the age of the cyborg is upon us. For the first time, neuromuscular electrodes that enable a prosthetic arm and hand to be controlled by thought have been permanently implanted into the nerves and muscles of an amputee. The operation was carried out recently by a surgical team led by Dr Rickard Brånemark at Sahlgrenska University Hospital in Goteborg, Sweden. Read More

Machine uses artificial intelligence to sort dead batteries

While it’s definitely important to keep the heavy metals in discarded batteries out of the environment, the sorting of all of the different types of batteries that arrive at a recycling depot could no doubt get extremely tedious. It’s the type of job that often goes to a machine. Well, such a machine has been invented. Called the Optisort, it can recognize about 2,000 types of batteries, and is currently being used to sort one third of those recycled in the UK. Read More
