Continuing the quest to design robots that could travel through our bodies to deliver drugs and cure disease, researchers at EPFL and ETH Zurich demonstrated tiny shape-shifting microrobots that swim through blood vessels. Made from hydrogel nanocomposites, the microbots can fold into various shapes for easy travel through tight spaces and flowing with dense, viscous, or fast-moving liquids. The microbots are peppered with magnetic nanoparticles so that they can be "steered" with an external magnetic field. From EPFL:
“Our robots have a special composition and structure that allow them to adapt to the characteristics of the fluid they are moving through. For instance, if they encounter a change in viscosity or osmotic concentration, they modify their shape to maintain their speed and maneuverability without losing control of the direction of motion,” says (EPFL researcher Selman) Sakar.
These deformations can be “programmed” in advance so as to maximize performance without the use of cumbersome sensors or actuators. The robots can be either controlled using an electromagnetic field or left to navigate on their own through cavities by utilizing fluid flow. Either way, they will automatically morph into the most efficient shape.

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!
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 […]
It’s too hot for yard sales, but hey: The internet is here for you. Here are the top ten deals on some of the Boing Boing Store’s best gear, just in time for summer. It’s everything from grills to security cameras to MacBook Pros, and they might be as low as they’re ever going to […]
