Autonomous Drones Team Up, Build a Bridge



Drones are really good at serving as our “eyes in the skies,” but, as it turns out, the flying machines are also pretty good construction workers.

Engineers at ETH Zurich recently fired up their computers, as well as a team of drones, and set them to work with one task: build a bridge. The drones, equipped with spools of rope, then autonomously assembled a rope bridge that researchers subsequently walked across. Read that again and let that sink in.

Drone the Builder

Inside the Flying Machine Arena at ETH Zurich, researchers basically look for cool new ways to use drones. Here, drones dance, play catch and even play with building blocks.

In their most recent demonstration, drones showed off their teamwork and knot-tying skills.

Once researchers fired up their drones and computers, the quadcopters went about their work on their own. The flight area is equipped with a motion capture system that constantly collects information about each drone’s position and attitude. That information is then fed into computers and algorithms parse the data to wirelessly send commands back to the drones. The drones weave in and out, up and down, and

Trident – the faster, sturdier OpenROV


Consumer drones have entered the mainstream recently, turning casual tinkerers into aerial cinematographers. With the launch of its latest low-cost submersible robot, named Trident, OpenROV is hoping to do the same with the underwater realm.

Trident looks a bit like a desktop hard drive, sleek white plastic with rubber side frames and a tapered, hydrodynamic body. It’s a substantial design upgrade from previous versions – which were reminiscent of a shoe-box – attributable primarily to functional necessity. Industrial designer Mikael Silvanto was able to work within these engineering specs “and turn it into a truly beautiful machine,” explains OpenROV co-founder Eric Stackpole.

Perhaps the most notable improvement is Trident’s speed. With a top rate of 2 meters per second, twice as fast as the previous version, the submersible provides an experience that early users describe as “like flying underwater”.

Since its founding in 2012, OpenROV has been a key player in the democratization of underwater exploration. Its low-cost, relatively shallow-depth products form one end of the cost / usability spectrum, while streaming deep-sea video from more advanced scientific assets like theOkeanos Explorer, Nautilus Live, and the R/V Falkor form

The World’s First 1,000-mph Car Has Been Unveiled

The world land speed record is in serious jeopardy.

That’s because the Bloodhound SSC was unveiled to the world in its final form Thursday in London, and this supersonic chariot won’t just break the land speed record, it’s expected to obliterate it. The Bloodhound represents the collaborative efforts of more than 200 global companies as well as eight years of designing and manufacturing. The team’s efforts have yielded a rocket on wheels that could reach a speed of 1,000 miles per hour — shattering the current world record of 763 mph.

The Need for Speed

Martin Roper, an events manager at the Bloodhound Technical Centre and one of the team’s fire and rescue officers, told The Verge that they wanted to build a car that would push the world record so far out of sight, no one would attempt to beat the record ever again. Based on the Bloodhound’s outrageous specifications, he may be right.

Doing Homework at Home

The number of Internet users in the US is at 86.75%, but as of 2013, about 25.6% of American households had no Internet access at home. This is a big problem for many students in low-income families that cannot afford their own Internet. Many teachers assign homework through the Internet, and usually requires research online to complete. The Internet has made it a lot easier to do any kind of work, including homework, but not if you do not have Internet at home.

The workaround

Many students use public libraries, coffee shops, school buses, and even sidewalks outside their schools where there is free Wi-Fi to do their homework. Some have to spend a few hours just standing on the curb doing their homework for the next day, and they do this regularly. Some call this the “homework gap.” Some people are fortunate enough to go online and get Lane Bryant coupons, but many children cannot afford to do their homework at home. It does not take a lot of imagination to see how non-conducive to learning, and potentially dangerous, this is for the schoolchildren.

Concern over claims about how technology affects young brains

Claims by Susan Greenfield, a senior research fellow at Lincoln College Oxford, that intense use of the internet and computer games can harm the adolescent brain are not backed by current scientific evidence, warn experts in The BMJ.

Scientists at University College London and the University of Oxford say, “despite calls for her to publish these claims in the peer reviewed scientific literature, where clinical researchers can check how well they are supported by evidence, this has not happened, and the claims have largely been aired in the media.”

They say there is currently no evidence from neuroscience studies that typical internet use harms the adolescent brain — and they are concerned that Greenfield’s claims “are not based on a fair scientific appraisal of the evidence, often confuse correlation for causation, give undue weight to anecdote and poor quality studies, and are misleading to parents and the public at large.”

Greenfield claims that social networking sites could negatively affect social interaction, interpersonal empathy, and personal identity. However, the authors say “the bulk of research does not support this characterisation.”

For example, they point out that adolescents’ use of social networking sites “has been found to enhance existing friendships and the quality

When to Use an Old Phone with Pay As You Go SIMS

I get used mobiles. I don’t go and buy the latest gadgets. What I choose to do is to buy a mobile from those folks that must have the latest gadget. That way the mobile I am getting is quite new. There are some people that keep a mobile just for a few months before trying a new one. I like finding deals from them. Then I get pay as you go SIMS. I actually have a couple of really old mobiles that I would not be afraid to lose or have destroyed that I take with me on days I am participating in outdoor adventures. I just pop a SIM into one of them and go about my day. If I were to lose or destroy the mobile, I am not losing a lot of money.

I like canoeing, kayaking, rock climbing and bicycling. Continue reading

All You Need to Know about iOS Development

iOS, a mobile operating system, has become very popular among app developers due to skyrocketing rise in the numbers of people using iOS devices – iPhone, iPad, iPod touch and Apple TV. Most clients want to join the bandwagon of iOS development as Apple acquires a big chunk of market shares in the mobile platform

iOS Development Cycle


There are many factors a client needs to take into consideration before starting the project of an iPhone app development. First, try finding answers to a set of questions, like what your app aims at, why people would embrace it, what all features must be there to swoon people, etc. Such a practice removes a lot of hurdles that crop up in coding phase. A plethora of options are available to decide the kind of iOS app you want to develop, such as entertainment, healthcare, travel, lifestyle, fun & games, etc. As an iOS developer you need to use Xcode, an integrated development environment (IDE) for iOS software. Once you download Xcode, you get a suite of software development tools, like IDE, simulators, a gamut of frameworks etc, to build apps for iOS devices.
