3D printing makes it incredibly easy to crank out new parts on a whim.
For example, I'm about to make the trek to California for RoboGames and want to use a Contour ROAM2 HD action camera to capture some of the action - especially ComBots with the massive steel robots trying to inflict mortal damage on each other. I have the camera and have access to all areas of the venue. What I don't have is three hands. I always carry my Canon 5D Mark II for the still images and some video, and I have a light Nikon bridge camera for competition videos. The challenge was to find some way to operate the Contour that was basically hands-free.
After considering, and disqualifying, several approaches, I finally decided to use my bicycle helmet. I tried the stock Contour helmet mounts, but didn't like the way they felt - primarily because the camera sticks off to one side and is heavy enough that it is noticeable, and irritating.
It only took a few minutes to take some measurements of the top of my helmet and design a short plug to slip inside one of the air vents. Printing a test part to check the fit took a bit longer, of course.
Surprisingly enough, the test part fit perfectly without any modifications. The next step is to add the top flange for the camera. The mount is a snug fit, so I plan on securing it with some tape or velcro because I want it to be easily removable.
We'll see how it works this coming weekend when it is put into real use at RoboGames 2013.

Of course it's only a plastic toy sword, but it's still pretty impressive.

I have to chuckle a bit every time someone asks me "Where are the robots we were promised?" Unlike the personal jetpacks that were also promised, robots are already here, all around us, if we take the time to look. They are embedded in the design of our refridgerators, washing machines, cars, trains, airplanes, and numerous other devices that make modern life possible while being almost invisible.
Of course we can debate over the definition of a 'robot', whether or not it should be limited to only being used to describe a humanoid or quasi-clone of humans. Frankly, I don't find that debate of much practical use nor interest. Today's automobiles don't share much of their physical form with the horseless carriages that they replaced.
In a similar fashion, I don't expect that the robots of the future will take on humanoid form, unless there is some unique advantage to be gained. Why should they? Only to make their human owners feel more at ease and to avoid the Uncanny Valley effect? Perhaps, but younger generations that have grown up with robots all around them will be less and less likely to feel anything strange or fearful.
In the meantime, robots, and our growing dependency on them to survive, will continue to proliferate with wild abandon.

Moore's Law, especially as it applies to huge amounts of processing power being packed into relatively cheap electronic devices like smart phones and digital cameras, has opened up new horizons. It wasn't very long ago when high frame rate video capture required special equipment at premium prices. That meant that only research labs or big companies could afford those analysis tools.
Now days affordable consumer level digital cameras incorporate the same functionality. While you still can't achieve ultra-fast frame rates, it is easy to record at 240 fps or higher.

For example, one of the major challenges for a humanoid robot hobbyist is developing good walking routines. Unfortunately the robot moves too fast for our eyes to follow its dynamics in detail. But by recording the robot movement at 240 fps, we can see exactly what's happening, and how all of the robots joints and body parts interact while walking. And, we can check a single frame, or repeat an entire sequence as many times as we like.
We have the tools, it's only a question of what we want to do with them...
I thought I was one of the first robot fanatics to sign up when Agostini Japan announced the Robi humanoid robot kit, but obviously some other people are way ahead of me. "Tubeegle" has already gotten far enough in the assembly process to try playing Rock, Paper, Scissors with Robi:
In my case, the 14th Robi issue arrived Saturday morning, so I'm a long way behind. At first my strategy was to wait until I had all of the issues, then tackle the assembly. But, after watching videos like this, and realizing that there may be a lot that can be done with a particially complete robot, I may start assembling each issue as they arrive. Anyway, that will have to wait until I get back from RoboGames.

It's SXSW time again already, so it should come as no surprise that companies involved in the interactive space are rolling out press releases and product announcements designed to leverage the excitement of the moment.
The most exciting, and interesting announcement that we've seen so far came from Makerbot on Friday. The company's CEO, and one of the founders, Bre Pettis stepped into the limelight to let the world know that they are developing a new 3-D scanner. Actual details are kind of sparse at the moment, because the company is still in the prototyping phase. No doubt will be extensive testing, learning, and redesign over the next few months as the product develops. There is currently no indication of the price or release timing, though the company did state that they will start accepting orders this fall.
The scanner consists of a turntable on which you mount objects you wish to scan. Lasers and cameras translate that object into a digital files. Bre said the scanner will be ideal for archiving, prototyping, replicating, and digitizing prototypes, models, parts, artifacts, artwork, jewelry, and other objects.
Assuming that the pricing is reasonable, and by that I mean in line with the pricing for the company's 3-D printers, then the new scanner will be a huge success. There are free solutions out there that usually involve taking a series of photos, then having the photos analysed to re-create the dimensions for the 3-D object. However the free software available online is either difficult to use, or requires significant attention to detail.
The new scanner, on the other hand seems to be much more straightforward and has some nice features that we help make it into the final product design. For example, the turntable, which we assume will be able to rotate the subject smoothly and repeatably. it appears that the company would like to expand its offerings to include products targeted at all the key steps in the design and manufacturing/printing process.
