MIT researchers designed and 3D-printed an array of soft, mechanical critters that are controlled by waving a magnet over them. The shapeshifters that fold up, crawl, grab things, and snap together into intricate formations may someday lead to new kinds of biomedical devices. For example, one of the devices "can even be directed to wrap itself around a small pill and carry it across a table." From MIT News:
“We think in biomedicine this technique will find promising applications,” says (MIT mechanical engineer Xuanhe Zhao.) “For example, we could put a structure around a blood vessel to control the pumping of blood, or use a magnet to guide a device through the GI tract to take images, extract tissue samples, clear a blockage, or deliver certain drugs to a specific location. You can design, simulate, and then just print to achieve various functions.”
In addition to a rippling ring, a self-squeezing tube, and a spider-like grabber, the team printed other complex structures, such as a set of “auxetic” structures that rapidly shrink or expand along two directions. Zhao and his colleagues also printed a ring embedded with electrical circuits and red and green LED lights. Depending on the orientation of an external magnetic field, the ring deforms to light up either red or green, in a programmed manner.
Inspired by the way plants grow, MIT researchers designed a flexible robot appendage that can work in tight spaces but is rigid enough to support heavy parts or twist tight screws. From MIT News: The appendage design is inspired by the way plants grow, which involves the transport of nutrients, in a fluidized form, up […]
Greg Olijnyk works as a 2D graphic designer, but his hobby is creating unbelievably wonderful 3D science fictional cardboard sculptures that sport motors and lights that animate them (some use photovoltaic cells for power, too).
Corridor produced this excellent parody of Boston Dynamics’ robots and the style of its promotional videos. It could be the trailer for a new Neill Blomkamp or Paul Verhoeven movie, but where the satire is immediately transformed into stress because there’s very little about it that seems unlikely or even beyond the fairly immediate future. […]
We’re living in the age of Big Data. As the driving force behind everything from Google’s famed algorithms to self-driving cars, massive sets of complex data can be found at the heart of some of today’s most exciting and important technologies. The Ultimate SQL Bootcamp Certification Bundle will give you the skills and tools you […]
So you missed Black Friday and Cyber Monday? Well, there’s one more holiday milestone coming up: Green Monday, on Dec. 16. It’s one of the busiest online shopping days for the simple reason that it will be 10 days before Christmas, which is when last-minute shoppers start to stress. Our advice? Don’t wait for that […]
Weighted blankets are officially a thing. And if you’ve ever tried one, you know there’s a reason for the fuss. Parents have known for generations that swaddling a baby has a profound calming effect, and the gentle pressure that blanket weights provide can have the same effect on restless sleepers. Pretty much all parts of […]
