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.
Diligent Robotics's Moxi is a robot created by Andrea Thomaz (a former robotics professor at UT Austin and Georgia Tech's Socially Intelligent Machines Lab) and Vivian Chu (one of Thomaz's former grad students); they funded by a National Science Foundation grant to create a robotic nursing aide that is designed to do routine, non-human-interaction chores […]
This is Digit, a new bipedal bot from Agility Robotics, out for a stroll in its hometown of Albany, Oregon. Next year, you’ll be able to order your own Digit, but the price hasn’t been announced yet. From Agility Robotics: Although still in testing, Digit is strong enough to pick up and stack boxes weighing […]
Swidl is a robot that can quickly slide its thin flat tongue underneath gooey spills without disrupting their shapes. I can’t begin to imagine a purpose for it other than forensic-grade vomit archiving (the given example is … meat towels?) but it’s amazing to watch in action. Thluuuuuuuup!
When it comes to passwords, there’s no such thing as paranoia. You want them secure and complex, and you definitely don’t want to repeat them on all your accounts. The trouble is, the internet seems to keep growing. And so do those accounts. Just one lockout from an important email or banking site is enough […]
With the rising temperatures on tap this summer, the climate is going to be a frequent topic of conversation, and those conversations won’t be happy ones. Luckily, there’s a way to do a little climate change of your own – in a safe and sustainable way. When it comes to personal air conditioners, EvaPolar is […]
Whether you’re using them for next-level selfies or steady tracking shots, gimbals are a must for anyone who wants to maximize the potential of these powerful smartphone cameras we’re all carrying around. But those smartphones are also supposed to be portable, and let’s face it: Gimbals tend to offset that advantage. Weighing in at just […]
