Microbots
-
One day microscopic robots could be crawling through your body, clearing out disease or delivering drugs. And now we’re one step closer to that future, as scientists from Cornell University have created tiny robots powered by pulses of laser light.
-
Scientists working in the field of microbots have taken inspiration from origami to produce what they say are first-of-a-kind machines, which can fold into different shapes to take on different tasks through the application of heat.
-
It was seven years ago that we first heard about Harvard University's HAMR cockroach-inspired robot. Although the bot was already on the tiny side, its designers have now created a version that's just half its size – it's time to meet HAMR-JR.
-
In future, many diseases may be treated by tiny robots delivering drugs. Taking inspiration from white blood cells, researchers from the Max Planck Institute have unveiled a new micro-robot design that can move against the current of blood flow.
-
Tiny robots could one day deliver drugs inside our bodies, but there are still a few hurdles. Now researchers have developed corkscrew microrobots that drill into cancer while they deliver drugs, preventing them being washed away by fluids.
-
Although we've previously heard about various groups' tiny "microbots," a new one is actually claimed to be the world's smallest microelectronic robot. What's more, it moves by shooting out dual jets of bubbles.
-
All living things are built with 20 amino acids in myriad combinations, so why not machines and robots? This is the inspiration for a novel fabrication method using a handful of multi-use parts to create all manner of tiny machines. Machines who eventually, may even be able to build themselves.
-
It’s entirely possible that micro-machines could one day be delivering drugs inside the body, with many designs proposed in recent years. The latest comes from the University of New South Wales (UNSW), which gets around under its own power using a system similar to how submarines rise and sink.
-
The potential for micro flying-robots in areas like search and rescue, agriculture and hazard detection is huge, but so are the hurdles. Researchers at the University of Southern California (USC) have been working on these problems with their Bee+, drawing inspiration from the insect world.
-
In future, microscopic robots could help heal us. While some of these have been capable of manipulating individual cells, researchers at the University of Toronto have developed a new way to get nanobots inside cells, and precisely control them once they’re in there.
-
The human body is full of wildly different environments, so any robots exploring them need to be able to adapt on the fly. Now, researchers at EPFL and ETH Zurich have developed micro-robots that can automatically morph in response to their surroundings.
-
MIT engineers recently managed to create cell-sized robots that could collect data about their environment, but were a little tricky to manufacture. Now, the team has found a way to mass produce these synthetic cells (syncells) through controlled fracturing of graphene.
