This Marker-Wielding Robot Can Teach Kids How to Code

Today's children are more in tune with technology than any generation that came before them. But when it comes to learning the language of computers, it's hard to make lines of HTML feel as exciting as the games they program. That's where Root comes in.

According to the Harvard Gazette, Root is a mobile, programmable robot developed by researchers at Harvard's Wyss Institute for Biologically Inspired Engineering. Using a tablet app, kids write "code" for Root and watch how different commands translate to the robot's actions in real life.

The compact, hexagonal device uses magnets and sensors to drive over the face of a whiteboard like a Roomba. A dry-erase marker inserted into its center allows the robot to draw different shapes based on how it's programmed. By introducing programming concepts and problem-solving skills to children, the designers hope to lay the foundation they'll need to tackle more advanced tasks down to the road.

Young beginners aren't the only ones Root is designed for. The app can be adapted to fit a range of skill levels, starting with a code language that uses pictures and simple actions leading up to actual Java Script for intermediate students.

The developers of Root are currently working towards building a curriculum around the robot and getting it into a real-life classroom. The majority of schools still don't teach coding to their students, but kid-friendly technologies like Root could help change that. And with computer skills already essential for nearly 80 percent of mid-level jobs, this is one lesson kids can't afford to miss out on.

IBM Unveils the World's Smallest Computer

The latest piece of technology to be zapped by the shrink ray of progress was recently revealed during IBM Think 2018, the computer giant’s conference that offers a sneak preview of its latest hardware. According to Mashable, IBM’s newest computer is so small that it could disappear inside a salt shaker.

That tiny black speck on the right? That’s the one. (It's mounted to a motherboard on the upper left of the left photo.) IBM claims the computer has several thousand transistors and has roughly the same kind of operating power as a processor from 1990. While that may not sound impressive, any kind of artificial intelligence in a product that small could have big implications for data management. IBM believes it has a future in blockchain applications, which track shipments, theft, and non-compliance. Its tiny stature means it can be embedded into materials discreetly.

As an example, IBM noted that the processor could be injected into a non-toxic magnetic ink, which can then be stamped on a prescription drug. One drop of water could make the ink visible, letting someone know it’s authentic and safe to take.

The tiny little motherboard and its processors are still in the prototype stages, but IBM predicts it could cost less than 10 cents to manufacture. The company hopes it will be commercially available in the next 18 months.

Apple Wants to Patent a Keyboard You’re Allowed to Spill Coffee On

In the future, eating and drinking near your computer keyboard might not be such a dangerous game. On March 8, Apple filed a patent application for a keyboard designed to prevent liquids, crumbs, dust, and other “contaminants” from getting inside, Dezeen reports.

Apple has previously filed several patents—including one announced on March 15—surrounding the idea of a keyless keyboard that would work more like a trackpad or a touchscreen, using force-sensitive technology instead of mechanical keys. The new anti-crumb keyboard patent that Apple filed, however, doesn't get into the specifics of how the anti-contamination keyboard would work. It isn’t a patent for a specific product the company is going to debut anytime soon, necessarily, but a patent for a future product the company hopes to develop. So it’s hard to say how this extra-clean keyboard might work—possibly because Apple hasn’t fully figured that out yet. It’s just trying to lay down the legal groundwork for it.

Here’s how the patent describes the techniques the company might use in an anti-contaminant keyboard:

"These mechanisms may include membranes or gaskets that block contaminant ingress, structures such as brushes, wipers, or flaps that block gaps around key caps; funnels, skirts, bands, or other guard structures coupled to key caps that block contaminant ingress into and/or direct containments away from areas under the key caps; bellows that blast contaminants with forced gas out from around the key caps, into cavities in a substrate of the keyboard, and so on; and/or various active or passive mechanisms that drive containments away from the keyboard and/or prevent and/or alleviate containment ingress into and/or through the keyboard."

Thanks to a change in copyright law in 2011, the U.S. now gives ownership of an idea to the person who first files for a patent, not the person with the first working prototype. Apple is especially dogged about applying for patents, filing plenty of patents each year that never amount to much.

Still, they do reveal what the company is focusing on, like foldable phones (the subject of multiple patents in recent years) and even pizza boxes for its corporate cafeteria. Filing a lot of patents allows companies like Apple to claim the rights to intellectual property for technology the company is working on, even when there's no specific invention yet.

As The New York Times explained in 2012, “patent applications often try to encompass every potential aspect of a new technology,” rather than a specific approach. (This allows brands to sue competitors if they come out with something similar, as Apple has done with Samsung, HTC, and other companies over designs the company views as ripping off iPhone technology.)

That means it could be a while before we see a coffee-proof keyboard from Apple, if the company comes out with one at all. But we can dream.
