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.
Hyundai developed a “walking car” and “unveiled” it at the CES trade show yesterday. As far as I can tell it’s just a mockup video, but the idea is timely. Traditionally, only flimsy and obviously impractical spider-legged robots could handle rough terrain, while two- and four-legged ones were too unstable to get far. Will Boston […]
The host of Life Where I’m From, a YouTube channel about life as a foreigner in Japan, visited a pop-up cafe with robot waiters that are remotely controlled by people with disabilities. The workers control the robots from their homes, and can speak with customers using a microphone. In December of 2018 I visited a […]
Dawn ver.β is a Tokyo cafe in Akasaka where all the table service is performed by 120 cm tall OriHime-D robots that are piloted by people who are paralyzed and work from home; it was inspired by a fictional cafe in the 2008 anime Time of Eve.
Building a website on WordPress has always been easy. But if you really want to make your website stand out from the growing crowd, you’re going to need some help. For our money, a subscription to Storeshock WordPress Themes & Elements does the trick almost as well as having a pro designer by your side […]
These days, there isn’t much our iPhone camera can’t do – except feel like an actual phone. Despite years of steadily increasing resolution and image sensing technology, we’re still taking shots awkwardly with two hands, fumbling for the shutter button. Leave it to an avid photographer to design Shuttercase, a versatile iPhone case that solves […]
Still determined to keep those New Year’s health resolutions? If you’re going to stick with the exercise plan, it’s enough of a challenge to budget your time. No need for your financial budget to take a hit, too. Here’s a more convenient – and cheaper – alternative to a gym membership or Peloton bike: Two […]
