Modular Robotics: When You Want More Robots in Your Robot

While robots have been making our lives easier and our assembly lines more efficient for over half a century now, we haven’t quite cracked a Jetsons-like general purpose robot yet. Sure, Boston Dynamics and MIT have some humanoid robots that are fun to kick and knock over, but they’re far from building a world-ending Terminator automaton.

But not every robot needs to be human-shaped in order to be general purpose. Some of the more interesting designs being researched are modular robots. It’s an approach to robotics which uses smaller units that can combine into assemblies that accomplish a given task. …read more

Quantum Electric Material Borrows from Japanese Basketweaving

Kagome is a pattern used to weave baskets from bamboo strips. The pattern is a symmetrical pattern of interlaced triangles that share corners. Scientists from MIT, Harvard, and Lawrence Berkeley National Laboratory have produced a kagome metal and found that it has exotic quantum properties.

Their paper, published in Nature (paywall), reports that the crystal made from layers of iron and tin atoms, causes electrons to flow in strange ways. The electrons bend into tight circular paths and flow along the edges without losing energy.

What is really interesting is that the effect persists at room temperature and above. The …read more

AI Watches You Sleep; Knows When You Dream

If you’ve never been a patient at a sleep laboratory, monitoring a person as they sleep is an involved process of wires, sensors, and discomfort. Seeking a better method, MIT researchers — led by [Dina Katabi] and in collaboration with Massachusetts General Hospital — have developed a device that can non-invasively identify the stages of sleep in a patient.

Approximately the size of a laptop and mounted on a wall near the patient, the device measures the minuscule changes in reflected low-power RF signals. The wireless signals are analyzed by a deep neural-network AI and predicts the various sleep stages …read more

How To Telepathically Tell A Robot It Screwed Up

Training machines to effectively complete tasks is an ongoing area of research. This can be done in a variety of ways, from complex programming interfaces, to systems that understand commands in natural langauge. A team from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) wanted to see if it was possible for humans to communicate more directly when training a robot. Their system allows a user to correct a robot’s actions using only their brain.

The concept is simple – using an EEG cap to detect brainwaves, the system measures a special type of brain signals called “error-related potentials”. Simply …read more

Umbrella Drones — Jellyfish Of The Sky

Mount an umbrella to a drone and there you go, you have a flying umbrella. When [Alan Kwan] tried to do just that he found it wasn’t quite so simple. The result, once he’d worked it out though, is haunting. You get an uneasy feeling like you’re underwater watching jellyfish floating around you.

A grad student in MIT’s ACT (Art, Culture and Technology) program, [Alan’s] idea was to produce a synesthesia-like result in the viewer by having an inanimate object, an umbrella, appear as an animate object, a floating jellyfish. He first tried simply attaching the umbrella to an off-the-shelf …read more
