Reusable microbots make meal of toxic metals

Researchers have developed a tube-shaped microbot that offers a cheaper and more effective way of removing heavy metals than previous methods. The self-propelled microbots use an outer layer of graphene that binds to lead ions it comes in contact with. The scientists found that they can remove 95 percent of lead from polluted water in one hour, and once they have a full payload, they can be cleaned and reused multiple times.Read More

3D-printed microscopic fish could be forerunners to smart "microbots"

Tiny 3D-printed robotic fish smaller than the width of a human hair may one day deliver drugs to specific places in our bodies and sense and remove toxins, thanks to research at the University of California, San Diego. The so-called microfish are self-propelled, magnetically steered, and powered by hydrogen peroxide nanoparticles. And they might be just the first chip off the block for a future filled with "smart" microbots inspired by other biological organisms such as birds, each with its own specialized functionality.Read More

Nanobot micromotors deliver medical payload in living creature for the first time

Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered nanobots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse.

Scallop microbots designed to swim through your bodily fluids

In the 1960s science fiction film Fantastic Voyage, audiences thrilled to the idea of shrinking a submarine and the people inside it to microscopic dimensions and injecting it into a person’s bloodstream. At the time it was just fantasy and as fantastic an idea as its title suggested. Today, however, micro-miniature travelers in your body have come one step closer to reality. Researchers from the Max Planck Institute have been experimenting with real micro-sized robots that literally swim through your bodily fluids and could be used to deliver drugs or other medical relief in a highly-targeted way.Read More

Nanomotors controlled within living cells

Imagine if it were possible to send tiny machines into living cells, where they could deliver medication, perform ultra-micro surgery, or even destroy the cell if needed. Well, we've recently come a little closer to being able to do so. Scientists at Pennsylvania State University have successfully inserted "nanomotors" into human cells, then remotely controlled those motors within the cells. Read More

Harvard's insect-sized HAMR robots bug out

Though there's much work to be done before miniature robots move exactly like insects, Harvard Microrobotics Lab is making strides with its latest prototypes. It recently demonstrated the Harvard Ambulatory MicroRobot (HAMR), a 4.4 cm quadruped that scurries around at up to 8.4 body lengths per second.Read More

Harvard's Robobee learning to fly

Harvard researchers are getting closer to their goal of developing a controllable micro air vehicle called the Robobee. The tiny robot was already capable of taking off under its own power, but until now it was completely out of control. By adding two control actuators beneath its wings, the robot can be programmed to pitch and roll.Read More

Swarms of air-bubble microrobots with laser engines could assemble live cells

Building robots out of bubbles is an intriguing idea in its own right, but propelling them with lasers is just plain crazy. The bubble microrobots, devised by the researchers from the University of Hawaii at Manoa, have no mechanical parts whatsoever, but can nevertheless be manipulated with very high precision. Combined into complex robotic systems, they could potentially be used to assemble larger objects, such as biological cells.Read More

New technique for mass-producing microbots inspired by pop-up books and origami

Inspired by origami and children's pop-up books, Harvard engineers have pioneered a means of mass-producing bee-sized flying microrobots. The breakthrough mechanizes the already state-of-the art process of making Harvard's Mobee robots by hand, by mass producing flat assemblies by the sheet which can be folded and assembled in a single movement. The technique, which cunningly exploits existing machinery for making printed circuit boards, can theoretically be applied to a multitude of electromechanical machines.Read More

Tiny magnetically-levitated robots could change the game for robotics

The past five to ten years have seen the birth of microbotics. A whole range of components that are vital for building robots, such as actuators, motors or batteries, became available in micro-scale only fairly recently. Finally enthusiasts got what they needed to put their own systems together, and the whole field benefited from their work. But there are obvious limitations to scaling down robots full of sensors, motors, and other mechanisms. That is, unless you make the machines extremely simple, which is exactly what Ron Pelrine of SRI International has done. His work on levitated microrobots may have powerful implications for robotics, and is likely to bring us a step closer towards fast, precise and affordable robotic systems comprising thousands, if not millions of microrobots.Read More
