As we learned earlier this year, researchers at ETH Zürich's institute for Dynamic Systems and Control are looking at ways in which flying construction robots can be programmed to autonomously build tensile structures. Now it appears they've taken a significant step forward. Literally. The team has demonstrated a rope bridge built by drones that can support the weight of an adult human as they walk across it.
Ever since the late 19th century, people have experimented with making textiles from natural-source-based gelatine, as a cheaper and less allergenic alternative to wool. Although the emergence of synthetic fibers largely put an end to that, a new technique may yet allow gel-based yarn to see the spotlight. The fiber is said to have an insulation quality similar to that of Merino wool, and the collagen used to produce it can be obtained from waste at animal-processing facilities.
We've seen tracked wheelchairs
before, that are able to take on steep or uneven terrain. For regular
surfaces, however, wheels make more sense. That's why a group of
students from ETH Zurich and the Zurich University of the Arts are
creating the Scalevo electric wheelchair, which features wheels for
cruising and tracks for climbing stairs.
Nanorobots hold great potential in the field of medicine. This is
largely due to the possibility of highly-targeted delivery of medical
payloads, an outcome that could lessen side effects and negate the need
for invasive procedures. But how these microscopic particles can best
navigate the body's fluids is a huge area of focus for scientists.
Researchers are now reporting a new technique whereby nanorobots are
made to swim swiftly through the fluids like blood to reach their
A Swiss joint venture has developed a hybrid-electric powertrain for road sweepers that's said to consume half the energy of diesel-hydraulic vehicles and reduce emissions by more than 60 percent. The modular system can also be adapted to cleaner fuel types such as hydrogen.
