What is left to map in the 21st century? Mostly underworlds, it turns out. One such underworld is the space beneath Antarctica’s Doston Ice Shelf, which a team of autonomous robots just spent a year mapping. While an entirely civilian and academic research mission, the project has valuable lessons about what long-term autonomous operations may
Everything is better with lasers, especially tiny robot insects. For robots of all sizes, power is a fundamental problem. Any robot that moves is constrained in one way or another by power supply, whether it’s relying on carrying around heavy batteries, combustion engines, fuel cells, or anything else. It’s particularly tricky to manage power as
Implantable fibers have been an enormous boon to brain research, allowing scientists to stimulate specific targets in the brain and monitor electrical responses. But similar studies in the nerves of the spinal cord, which might ultimately lead to treatments to alleviate spinal cord injuries, have been more difficult to carry out. That’s because the spine
