World's First Passenger Drone Unveiled

Now here is a product that every person has almost certainly dreamed of owning; a personal transportation vehicle that evokes images of a future where traffic jams are no longer an issue. This video, shot from the floor of the 2016 CES convention in Las Vegas centers on a passenger size drone being developed by a Chinese company called Ehang. The vehicle will operate completely autonomously, with no input needed from the passenger to get from point A to point B. Co-founder of the company Derrick Xiong explains that since the passenger will not be in direct control over the flight of the vehicle, it will require no specialized license to operate. This sounds scary at first, but it will be much safer in the end to have computers controlling the navigation of these vehicles. It will utilize a wide variety of sensors and computer components to control all flight operations and navigate to and from destinations completely autonomously. The only interface in the drone will be a singular tablet, which will give the passenger control of take-off and landing locations, and the ability to adjust the climate controls inside the vehicle. At the time of the video, the vehicle is capable of transporting one person to an altitude of roughly 11500 feet in the air, with a cruising speed of around 63 miles per hour. This coupled with the life of its internal batteries will allow the vehicle to fly around 20 miles non-stop, and stay in the air for around 23 minutes. Not a huge range considering how far some people commute to get to work every morning, but with more efficient batteries this thing could definitely start to get a much longer flight range. For those of you concerned with the safety of such a new type of transportation, Ehang says that in the event of an emergency, they will be able to remotely control every vehicle in their fleet individually, in order to override faulty commands or to safely land the vehicle in case of technical malfunction. The drone has 8 propellers instead of the typical 4 propeller design to help with redundancy; in a situation where one of the rotors stops functioning the second rotor will spool up faster to compensate and still allow for a controlled descent. All that said, at a price tag of between two hundred and three hundred thousand dollars, you won’t be seeing too many of these out in the skies anytime soon. Add to that the safety concerns of relying solely on computerized navigation automation to control the vehicle with the passenger being completely helpless in the case of a malfunction, and the general annoyance to the public once there are a bunch of these out there flying around. To be able to generate enough lift to fly a vehicle of this size you have to displace a lot of air (think of a helicopter), and it is very noisy to do so, so the neighbors might not be super happy about one of these taking off and landing twice a day from your backyard.

Disney Unveils Super Cool Wall-Climbing 'Gravity Defying' Robot1m31s

Disney Unveils Super Cool Wall-Climbing 'Gravity Defying' Robot

Disney Research Zurich and ETH have collaborated to design a super cool, gravity defying robot. This remote-controlled machine has the ability to drive around on the ground and then transition fairly seamlessly to moving vertically along walls with the help of some very cool engineering. The Robot is aptly named VertiGo, and has one very unusual feature that allows it to travel in a second dimension usually reserved only for flying vehicles. With the help of two drone propellers built into the body of the machine, it can provide enough thrust to keep itself glued to the wall as it drives around seemingly defying the laws of gravity. As the machine approaches a vertical surface, it slowly drives its front wheels up the wall, and as its orientation changes, the angle of the propellers also change to compensate for the weight of the vehicle. It can then drive around on the wall as though it were still safely on the ground since the propellers provide enough thrust to keep the wheels securely stuck to the wall. To facilitate this kind of unusual locomotion, the machine has to be extremely lightweight and so the designers had to come up with some very cool engineering to allow it maintain its orientation without smashing to the ground. The main chassis is constructed using carbon fiber with a very cool honeycomb design to increase the strength and durability of the vehicle. Many of the parts have also been 3D printed to save weight and maximize strength. The designers even went as far as using mostly plastic screws to assemble the machine in order to save every ounce of extra weight. It’s hard to say what the designer’s intentions for the main use case of this robot will be, but the technology is very cool regardless. With the rising popularity and usefulness of drones being increasingly apparent these days, it’s easy to see from this machine how the techniques that allow those aforementioned flying machines to be so stable and agile in flight, can be taken and implemented in new and original ways to other methods of travel. The scalability of this design is questionable however, because as the size of the robot increases, the propellers have to move more and more air to maintain its orientation, and as you can see by the magically floating mattress in the video, it already has to push a lot of air. Window washing seems to be the only thing that immediately comes to mind as far as usefulness of this technology, but even then, considering how lightweight it needs to be to maintain its wall-crawling orientation, high winds could be a serious problem while driving up the side of a massively tall skyscraper. As lightweight as it is, we still think it could do some damage falling from such a height. All joking aside though, this technology could have some very innovative way to deal with emergency situations such as fire and bomb threats. Its incredible mobility could be used to scout out locations and situations where humans would have a very hard time determining the best way to proceed.

The Practicality Of Diamond Shapes On Measuring Tape2m58s

The Practicality Of Diamond Shapes On Measuring Tape

Of course you know what a tape measurer is used for, but most people have no idea what those tiny black diamonds are for. It's one of those things that we've all seen, but likely wouldn't be able to tell you what it's used for. This might come in handy the next time you break out the tools to get some renovation work done on your home. One of the most mind-bending has to be the black diamonds which are on some versions. They usually sit above the numbers, nestled into the lines which show segments of an inch. It's pretty obvious they aren't just for decoration, but you probably have no idea what they are actually for. Well, turns out they are used by people who make a living in construction. It stands to reason those who make money for building will need tape measures that are a little more in depth than those of us who just get them out to check our height. The black diamonds are actually called truss marks (also known as stud or joist marks). A truss is a framework, usually meaning rafters, posts and struts which support a building. So those innocuous little marks actually help professionals with truss layouts, meaning it speeds up the process of knowing where each section of whatever you're laying should go. Unless you use a measuring tape daily, you may have never even noticed those small diamond-shaped details on the top scale. And, even if you have, we bet that you only have a best guess as to what they might mean.They’re not just cute, they’re also super helpful! What do these black diamonds mean anyways? The black diamond is meant to signify the center area between studs in a home or building. The symbol will always be set at the 19.2-inch mark, but to best use it to its advantage, you must first take the time to understand the “8-foot rule.” Unless you use a measuring tape daily, you may have never even noticed those small diamond-shaped details on the top scale. And, even if you have, we bet that you only have a best guess as to what they might mean.They’re not just cute, they’re also super helpful! What do these black diamonds mean anyways? The black diamond is meant to signify the center area between studs in a home or building. The symbol will always be set at the 19.2-inch mark, but to best use it to its advantage, you must first take the time to understand the “8-foot rule.” As the man in the video says: “Many tape measures add red numbers (or some other graphical standout) every 16-inches, a very common spacing for studs in house framing. This spacing allows for six supports in each 8-foot length. If you want to locate a center between the studs, the black diamond is your best bet”. The woodworker goes on explaining: “If you divide the 8-foot space we have been using by 5 we get a spacing of 19.2”. The black diamonds on the tape measure represent that spacing. The first black diamond is at 19.2” and after that black diamonds appear at 38.4”, 57.6”, 76.8” and 96”, or 8-feet. That is one less stud for every 8-feet of wall, counting the beginning and end studs”. Pretty cool, huh? Basically, if you know that your walls were built following this standard stud placement formula, then, instead of breaking out that cumbersome stud detector, you should be able to just use your measuring tape to locate them. Let's take a look at the video, shall we?
