Sure. http://www.smithsonianmag.com/smart-news/china-launches-larg... Bio-fouling and corrosion are still huge problems though.

Alas, there is no muscle in the robot kingdom! A lot of interesting work has been done recently on direct drive or minimally geared legged robots, however - check out Ghost Robotics for an example. [ https://www.ghostrobotics.io&#

The flex-spline is a spring that is constantly under compression, so there is no "rattle" between teeth. There is one downside to this inherent springiness of harmonic drives, which is some play at the end effector. I worked on a

What they don't mention is that Makani has thoroughly proven that the concept is not viable. The wing-on-a-string is too unstable and too expensive to compete with plain old wind turbines. Edit: removed unsourced claim about the future

Because cheap capital assets produce lousy results, and good ROI requires trained, professional operators.

Who is all this engineering effort for? How many people live in fortresses of solitude where they need to automatically track the cars that come down the driveway? How many Silicon Valley billionaires need a computer to tell them what to we

If you've ever had coffee or tea on a plane, you probably already know that the water usually tastes terrible anyway. So, germs or no germs, stick to cold drinks. Like gin and tonic.

While I think your business plan needs a lot of work, I am very sympathetic to your goals and inspiration. I have often thought that the California hills would benefit from "borgo" style development.

This is complete nonsense. The only sense in which Boston Dynamics is building "military" robots is that no one other than DARPA was willing to fund the development of these expensive toys. They have no real military use. Andy Rub

It's like Google Home, without the enormous company full of brilliant software engineers behind it?

Also, what is the benefit of a "bezel-less" phone? I always put cases on my phones, ever since I dropped one and spider-webbed the screen some years back. Without a bezel, the case will be covering up part of the screen...

That's like saying it's impossible to design a motherboard because you can't show all the bypass capacitors on the top level schematic. Hierarchical design and layers of abstraction are vital in both hardware and software.

The "humanitarian" part is just PR: "Brin wants the gargantuan airship, funded personally by the billionaire, to be able to deliver supplies and food on humanitarian missions to remote locations. However, it will also serve a

Sailboats devote a lot of structure and surface area to propulsion. All that stuff gets in the way of loading and unloading containers. Also, they're slow.

Very happy to see the Global Explorer ROV still out there, hard at work. This vehicle was Chris Nicholson's baby and it looks like the crew at Oceaneering are keeping his legacy going. Chris was one of the early inventors / develo
