Here is a slightly different project created with the Robot Operating System at the core of its programming. While I think he might have wanted to spend a bit more time training his Voice Recognition interface before making this video, he did do a wonderful job with this project. If you are curious about how exactly this works, he has lots more videos on his You Tube Channel, plus he has uploaded his source code and hardware interfacing instructions to Sourceforge. I am sure it will be no surprise to anyone that this is a project involving AstroMech, the R2 Builders Club.
Robonaut 2 had some nice glowing reports of earning its keep in orbit on the ISS back in March… This project was an unusual collaboration, 15 years in the making, between NASA and General Motors, each of whom had their own reasons for wanting to develop a much more advanced robot than anything then available. There was another requirement in the development criteria; it had to be a robot that could do things like a human would do them, using a similar visual feedback and manipulatory structure. In plain English, two eyes looking forward from its head, and hands with opposable thumbs on person length arms, so it could use the same tools, vehicles, and other components of a human environment to do jobs that assisted people or freed them up for other tasks.
They did such a good job on it that the team and project are now up for the Sammies Award this year, and you can read a great interview here with one of the original developers about their approach to the entire endeavor.
What has happened since? Well, not as many news stories it seems, but some very exciting stuff if you were thinking about cobbling together your own variant. They have now released the Robonaut 2 Simulator as a free download over at ROS.org (Robot Operating System). The tested versions are only certified to run on Ubuntu 12.04 since that was the box they tested them on (what a surprise, the very version I upgraded my own Ubuntu box to just a few days ago), but the dependencies are pretty generic, so it should run on most scientifically oriented recent Linux builds. If you need to compile something for a more specific system, you can grab the source code here, tweak it for your own hardware, and make any other changes your system might require.
All of which means you can write your own instruction sets for the robot and see exactly what happens when it carries them out! There is a very good chance this is going to become one of the core R.O.S.’s going forward, not least because it is open source, so if you are considering a future in robotics I strongly recommend downloading this as a way to explore and learn the possibilities.
A Tesla Coil is a transformer that is able to generating extremely large voltages, which allows it to throw huge but extremely short-live sparks. So what looks like one long spark is actually a bunch of sparks each second. As any musician with a scientific background will tell you, a given tone is a given frequency of vibration, producing each unique note. So by adjusting the sparks per second from the coil, different notes can be played. And that is exactly what they did in this video; enjoy!
The coil was invented by Nikola Tesla, who also invented AC power, the electric motor, the alternator, the generator, the audio speaker, radio (they took the patent away from Marconi when it turned out it was based on 17 of Tesla’s patents), the florescent light four years before Edison used brute force slave labor to invent the light bulb, and ever so much more which he patented. He also invented some stuff the patent office couldn’t figure out how to process, like broadcast energy and the related wireless charging of batteries (a company finally figured out how to make a profit on that one a decade or so ago for all our portable electronics), Ball Lightning, Radar (it was WWII before anyone decided building that could be useful), and oh, yeah, that earthquake machine he almost sank Long Island with. Tesla has been one of my personal heroes since I was a kid, and if you don’t know about him it is time you learned.
I am still trying to decide if this is a major tech advance or just creepy. Using some Augmented Reality goggles and software, a Japanese engineer has come up with a way to date his favorite virtual idol, Hatsune Miku. A bit creepy, was my first reaction. But what if you then used a Kinect or other low cost motion capture solution to drive your anime character of choice in real time with an actual person wearing the avatar? That could end up being a new level of RPG and Cosplay interaction amongst consenting adult geeks. Perhaps it is time to break out your own copy of the ARToolKit and start programming your glasses.
I wanted to break from my usual kind of entry for a moment and cheer on the MOD production process, meaning Manufacture On Demand. Warner Brothers, Shout Factory, MGM, and several others have done this with a lot of titles which have not been available for a while, and it is a great business model for the digital age. You pick one of the titles in their MOD catalog and put in your order, at which point they burn you a copy of the CD or DVD on their industrial grade reproduction gear, print out a label, and send it your way. For the customer, thousands of titles you could not previously get your hands on except possibly in very low quality bootleg format are now accessible. For the manufacturer, titles they own but were not previously making any money on can now turn a small but steady profit for them, without the loss incurred by going to a full press run when the demand for the product is not there. If it turns out the demand is there as evinced by the number of folks putting in orders for an MOD title, they can then release the disk or box set as a full press run (“press” being a leftover term from pressing vynal records, the original media distribution format).
Obviously this process is good for both music CDs and video DVDs, but it doesn’t stop there. With the advent of 3D printing, objects of all kinds can be put through the manufacture on demand process. Even better, they might be designed anywhere in the world, but you could have them printed locally and avoid the shipping costs, downloading the printing template across the web. Did you know this is the same technology Jay Leno uses to produce mil spec perfect replacement parts for his vintage automobile collection? This stuff is available today, and although it can be a bit pricy, there are also open source 3D Printing options worth looking into, such as the ongoing MIT research.
Take a deep breath and focus as Helen McCarthy presents the history of Manga from its beginnings in 1860’s Japan to the current crises it faces from pirates powered by broadband in a mere 8 minutes and 22 seconds. This is one of a series of 12 presentations on Japanese Creativity put together by the British Design and Art Direction educational charity, also known as B&AD. If you don’t know who the non-profit educational charity B&AD is, the next video put together by BBC4 will give you a glimpse into the organization. Finally, just for balance, a video of Helen as part of an Anime Filk group at a Con in Iowa in 2010. Thanks to Crunchyroll for the heads up on this one.
