News in Brief
A new type of mini drone can pull a lot more than its own weight.
The drone latches onto a surface and uses a cable to reel in objects up to 40 times its mass, researchers report. This feat is a marked improvement over other flying robots, which generally can’t tote objects heavier than about their own weight (SN: 2/7/15, p. 18). The new palm-sized flyer, described October 24 in Science...
To help self-driving cars drive safely, scientists are looking to an unlikely place: the sea.
A new type of camera inspired by the eyes of mantis shrimps could help autonomous vehicles better gauge their surroundings, researchers report October 11 in Optica. The camera — which detects polarized light, or light waves vibrating on a single plane — has roughly half a million sensors that...
Much like a silkworm uses a single thread to swaddle itself in a cocoon, a new kind of robot spins a single strand of material around its body to build custom-shaped fiberglass structures.
The new robots could create customized construction materials on-site, unlike other industrious bots that assemble premade building blocks (SN: 3/22/14, p. 8). Fleets of the fiberglass-spinning bots...
A new type of soft robot gets its power from the skin it’s in.
Robotic skin that bends, stretches and contracts can wrap around inanimate objects like stuffed animals, foam tubes or balloons to create flexible, lightweight robots. Removable, reusable sheets of this artificial skin, described online September 19 in Science Robotics, could also be used to build grippers or wearable devices...
News in Brief
A new winged robot helps explain why airborne insects are so doggone hard to swat.
Scientists have wondered how these tiny pilots pull off such rapid twists and turns, but researchers haven’t been able to test all their ideas by monitoring real insects or using tethered robots. Now, a free-flying, insect-inspired robot, described in the Sept. 14 Science, gives researchers an alternative...
