New MIT Technology to Help Drones Dodge Obstacles May Make Deliveries Easier

New technology developed by MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) may help drones dodge collisions as they fly, making things like drone pizza delivery a whole lot more plausible on a large scale.

Whether you’re a human or a drone, moving through a city always involves a certain amount of uncertainty. Will that light turn green as you approach? Will a pedestrian bump into you? Will a pigeon fly in your face? Will there be a sudden road closure for a parade, or a newly installed crane at a construction site? And if there’s one thing that machines tend to be bad at, it’s dealing with uncertainty. For a fast-flying drone, navigating with a static map just won’t cut it in the real world.

So CSAIL researchers created NanoMap, a new system that can model uncertainty, taking into account that, as a drone flies, the conditions around it might change. The technology helps the drone plan for the fact that it probably doesn’t know precisely where it is in relation to everything else in the world. It spends less time calculating the perfect route around an obstacle, relying instead on a more general idea of where things are and how to avoid them, allowing it to process and avoid potential collisions more quickly.

It features depth sensors that constantly measure the distance between the drone and the objects around it, creating a kind of image for the machine of where it has been and where it is going. “It’s kind of like saving all of the images you’ve seen of the world as a big tape in your head,” MIT researcher Pete Florence explains in a press release. “For the drone to plan motions, it essentially goes back into time to think individually of all the different places that it was in.”

In testing, the NanoMap system allowed small drones to fly through forests and warehouses at 20 miles per hour while avoiding potential collisions with trees and other obstacles.

The project was funded in part by the Department of Defense’s DARPA, so it could be used as part of military missions, but it would also be helpful for any kind of drone-based delivery—whether it’s ferrying relief supplies to combat zones or your latest Amazon Prime package.

Mickey Mouse Is Getting His Own Beats By Dre Headphones

Since debuting in a black-and-white cartoon in 1928, Mickey Mouse has grown into an icon recognized around the world. To celebrate the character's 90th birthday, Beats by Dre has designed him his very own pair of Solo3s, The Verge reports.

The special-edition, wireless headphones depict a pattern of classic Mickeys against a gray background. They come in a gray felt carrying case—a nod to the material used to make the Mickey Mouse ears sold at Disney parks. The purchase also includes an enamel pin and decal sticker commemorating the anniversary.

At $329.95, the Mickey headphones cost about $30 more than conventional Solo3 headphones, but it's not unusual for Beats to charge extra for limited-edition designs. In 2014, the company released Hello Kitty Solo2s for the character's 40th anniversary for $50 more than the headphones' standard selling price.

The Mickey Beats will be available starting November 11—a few days before the 90th anniversary of the premiere of Steamboat Willie. You can pre-order them on Amazon today.

This Smart Mug Alerts You When You've Had Too Much Caffeine

Ember

Since 2010, Ember has been giving perfectionists ultimate control over their morning coffee. Their travel mug lets you set the preferred temperature of your drink down to the degree when you're on the go, and their ceramic cup allows you to do the same in the office or at home. Now, in addition to telling you how hot your beverage is at all times, Ember lets you know how much caffeine you're consuming through Apple's Health app, CNET reports.

Ember's new feature takes advantage of the same Bluetooth technology that lets you control the temperature of you drink from your smartphone. Beginning October 17, you can connect your Ember vessel to your Apple device to keep track of what you're drinking. If you drink all your tea and coffee from an Ember mug, the Health app should be able to give you a rough estimate of your daily caffeine intake.

Ember wasn't originally designed to measure caffeine content, but its built-in sensors allow it do so. In order to maintain a constant temperature, the mug needs to know whether it's full or empty, and exactly how much liquid it's holding at any given time. The feature also gives you the option to preset your serving size within the app if you drink the same amount of coffee everyday. And if you like to drink specific beverages at their recommended temperatures, the mug can guess what type of drink it's holding based on how hot it is.

The new caffeine-calculating feature from Ember is especially useful for coffee addicts: If the mug senses you've exceeded your recommended caffeine intake for the day, it will alert you on your phone. Here are some energizing caffeine alternatives to keep that from happening.
