This Drone Can Swim Underwater

Consumer-level drones have grown so much in popularity over the last few years that one could argue the idea has become a little ho-hum. But a team at Oakland University's Embedded Systems Research Laboratory has developed what may be the next big thing in drone tech with The Loon Copter, which appears to be the first multi-rotor drone capable of flying, landing on water, and diving beneath the surface.

Named after the aquatic birds (also called divers in the UK), the drone was developed as a proof-of-concept vehicle in a project that began in 2014. Mashable reports that when the device lands on water, a buoyancy chamber helps to keep it afloat. The drone can then fill that same chamber for a controlled dive, and turn 90 degrees to use its propellers to steer like a submarine.

The prototype, now in its third iteration, recently became an international semifinalist at the 2016 Drones for Good competition, which will award a $1 million winner in February. The contest entry page lists possible uses for the drone, including "underwater search, environmental monitoring and above and underwater structure inspection," though it sounds like that's only the beginning. The caption on the footage above reads: "We are looking into extended wireless range underwater, navigation underwater, a redesign of the hull for more efficient diving, payloads for different applications, etc."

Watch the drone in action above, and check out the project page to learn more about the innovative design.

Honda Debuts a Rain-Proof Disaster Robot That Can Climb Ladders

A new Honda robot could signal the future of disaster response technology. According to IEEE Spectrum, the Japanese company recently debuted a prototype for a cutting-edge disaster-response robot agile enough to climb ladders, ascend stairs, maneuver over pipes, and move through narrow spaces, among other capabilities.

Honda unveiled the prototype for the E2-DR at September’s IEEE/RSJ International Conference on Intelligent Robots and Systems in Vancouver. The slow-moving humanoid robot looks like a beginning skater stepping onto the ice for the first time, stepping cautiously up stairs and through small spaces, but the fact that it can navigate these kinds of obstacles is a feat. Scaling ladders and walking up and down stairs are usually no easy tasks for robots, and both are among the challenges featured in the annual DARPA Robotics Challenge obstacle course—which is infamous for making very, very expensive robots fall all over the place.

Designed to inspect, maintain, and provide disaster response in places like factories and power plants, the E2-DR is 5.5 feet tall, weighs around 187 pounds, and can run for about 90 minutes at a time. Crucially, it’s less than 10 inches thick back-to-front, allowing it to squeeze through small corridors laterally.

The robot can reverse its knees to allow it to keep them from bumping against stairs as it walks, and its hands can grip ladders and rails. It can also open doors and climb on all fours. It’s equipped with rangefinders, cameras, and 3D sensors so that it can be piloted remotely.

Because it’s designed to work in disaster zones (like within the Fukushima power plant) the robot has to be able to withstand water, debris, dust, and extreme temperatures. It’s already been able to climb up and down a ladder in the face of 1 inch-per-hour rain, according to Honda.

IEEE Spectrum notes that we haven’t seen it fall, and falling down is, despite how silly it looks in testing, an important thing to test before sending robots into the field. In unpredictable settings and rough terrain, it’s likely that a robot is going to misstep and fall down at some point, and it needs to be able to not just withstand the fall, but get itself back up.

The E2-DR is just a prototype, and Honda will continue to work on it for the foreseeable future. For now, though, it’s made an impressive start.

Want to Become a Billionaire? Study Engineering

If you want to get rich—really, really rich—chances are, you should get yourself an engineering degree. As The Telegraph reports, a new analysis from the UK firm Aaron Wallis Sales Recruitment finds that more of the top 100 richest people in the world (according to Forbes) studied engineering than any other major.

The survey found that 75 of the 100 richest people in the world got some kind of four-year degree (though others, like Bill Gates and Mark Zuckerberg, attended a university but dropped out before graduation). Out of those who graduated, 22 of those billionaires received engineering degrees, 16 received business degrees, and 11 received finance degrees.

However, the survey doesn't seem to distinguish between the wide range of studies that fall under the "engineering" umbrella. Building a bridge, after all, is a little different than electrical engineering or computing. Four of those 100 individuals studied computer science, but the company behind the survey cites Amazon's Jeff Bezos (who got a bachelor's degree in electrical engineering and computer science from Princeton) and Google's Larry Page (who studied computer engineering at the University of Michigan and computer science at Stanford) as engineers, not computer scientists, so the list might be a little misleading on that front. (And we're pretty sure Bezos wouldn't be quite so rich if he had stuck just to electrical engineering.)

Aaron Wallis Sales Recruitment is, obviously, a sales-focused company, so there's a sales-related angle to the survey. It found that for people who started out working at an organization they didn't found (as opposed to immediately starting their own company, a la Zuckerberg with Facebook), the most common first job was as a salesperson, followed by a stock trader. Investor George Soros was a traveling salesman for a toy and gift company, and Michael Dell sold newspaper subscriptions in high school before going on to found Dell. (Dell also worked as a maitre d’ in a Chinese restaurant.)

All these findings come with some caveats, naturally, so don't go out and change your major—or head back to college—just yet. Right now, Silicon Valley has created a high demand for engineers, and many of the world's richest people, including Bezos and Page, earned their money through the tech boom. It's plausible that in the future, a different kind of boom will make a different kind of background just as lucrative. 

But maybe don't hold your breath waiting for the kind of industry boom that makes creative writing the most valuable major of them all. You can be fairly certain that becoming an engineer will be lucrative for a while.
