Automaton

Just in case you'd ever lain awake at night wondering to yourself how you might build a robotic hand you could eat... well, wonder no more.

More information can be found at the MAYA Make group's website. Happy fooding.

Having attended a wonderful wine tasting last night at a former professor's house, I've been feeling particularly oenophilic. During the tasting the professor told us about a lot of the technology vineyard owners have started using to track their crops. Since vines produce different fruit depending on shade, temperature, amount of water, type of soil, and so on, a good vineyard owner needs to know all about the different conditions all over his or her vineyard -- and small, cheap sensor technology only makes that easier. This of course led me to the natural conclusion: my wine could only be better if a robot is involved!

So what can robots do for a wine geek like me? I could purchase my very own "Robo-sommelier" to see if I'm actually getting what I'm buying -- using infrared light, it can tell what the type of the wine is without even opening it -- or it could learn my tastes and be able to recommend a wine to pair with my dinner.

Before the wine gets to my table, a vineyard owner might use an automated tractor to care for the vines. It can navigate using the wires that the vines grow on and can tow a sprayer or other equipment, preventing a human from having to do the long, dull task of driving the tractor through a huge vineyard. A 5-DOF robotic hand combined with a vision system might be doing some of the harvesting or care for the bunches of grapes on the vine. A friend at the wine tasting with me mentioned having seen one vineyard in which a robotic system rotated and tipped bottles slightly each day as they aged.

The agriculture industry is really embracing robotics and automation (Rocona is one example; John Deere and others are following suit), but it will be interesting to see if the wine industry actually adopts the technologies being created for them. Vineyard owners pride themselves on understanding their crops and how climate conditions will affect their output; sommeliers and wine aficionados are proud of their tasting abilities and standards. Will these people really want to hand over their art to machines?

Last year, Blake Hannaford and Jacob Rosen of the University of Washington’s BioRobotics Lab wrote an article for Spectrum about their surgical robot, Raven, and a field test in the California rangelands, where a surgeon commanded the robot remotely.

Early this year, Raven headed out to another extreme environment: the Aquarius underwater habitat off Key Largo, Florida. In the experiment, part of NASA's Extreme Environment Mission Operations (NEEMO) project, surgeons teleoperated the two-armed robot all the way from Seattle.

Automaton spoke with Hannaford to get the details.

And speaking of robots on the battlefield, Wired's Danger Room points to a Defense News story about a U.S. Army $280 million contract to buy 3000 Negotiator robots from Robotic FX. The Negotiator tactical robot [photo above] is a "45-pound bomb detector with infrared cameras used by hundreds of state, local and federal law enforcement agencies around the U.S.," Defense News reports, adding that an "initial delivery order will be for 101 Robotic FX Negotiators, marking their first use with the U.S. military on the battlefield," where they will be used to clear caves and search for explosives.

NASA today announced the recipients of their SBIR ("Small Business Innovation Research") grants, among which were quite a few robotics projects. Lots of them have to do with power sources or sensors, but one I found particularly interesting is the DC brushless motor that can withstand the harsh atmosphere of Venus. From the proposal:

Honeybee Robotics proposes development of high temperature scoop and joint; and continued development of an extreme temperature brushless DC motor and a resolver. All hardware will be demonstrated in simulated Venus surface conditions. During Phase I, a first-generation prototype BLDC motor and resolver were designed, built and tested in Venus-like conditions (460oC temperature, mostly CO2 gas environment). The Phase I tests demonstrated the feasibility of the design through verification that the motor and the resolver can operate at 460oC for an extended period of time. A further developed and optimized version of this motor and resolver could be used to actuate sample acquisition systems, robotic arms, and other devices outside of an environment-controlled landed platform on the surface of Venus.

460 deg C? For the non-metric among us, that's 860 deg F. Wow.

The rest of the robotics-related SBIR grants can be found here and here.

Cars aren't enough for Toyota -- just like Honda, they're making robots. Both Honda and Toyota, based in Japan, are trying to address the concerns of the aging populace and relatively low birthrates that will result in lots of elderly needing care, and not enough people to provide it. Both companies are focusing on development of humanoid robots with a lot of dexterity, which Toyota consistently demonstrates by having the robots play musical instruments.

The newest addition to Toyota's line of Partner Robots is a violin-playing bot that demonstrates new developments in manipulation and dexterity, which are essentially to working with small objects in a standard human environment. Many of the partner robots can walk, though one is wheeled, and some can carry on simple conversations. Eventually the goal is to have these piloted in nursing homes and hospitals with the elderly to see how they do, and Toyota says they want to have them in homes in 2010.

How realistic is that? The Partner robots (and Asimo) are both still largely tele-operated and incredibly expensive. So much work goes into recreating human balance, manipulation, size, shape, and aesthetics that getting a product to market is delayed perhaps much further than a robot less humanoid and more specialized -- is that the right path to be taking? Will the humanoid form make adoption easier or more difficult?

Here's a video with a good closeup of the robotic hand on the violin. It is definitely impressive. Incidentally, it may not be as much of a robot, but I have to say also that the way the wheelchair deals with the bump in the road is amazing as well.

IEEE Spectrum's Sarah Adee reports:

Dean Kamen's “Luke arm”—a prosthesis named for the remarkably lifelike prosthetic worn by Luke Skywalker in Star Wars—came to the end of its two-year funding last month. Its fate now rests in the hands of the Defense Advanced Research Projects Agency (DARPA), which funded the project. If DARPA gives the project the green light—and some greenbacks—the state-of-the-art bionic arm will go into clinical trials. If all goes well, and the U.S. Food and Drug Administration gives its approval, returning veterans could be wearing the new artificial limb by next year.

The Luke arm grew out of DARPA’s Revolutionizing Prosthetics program, which was created in 2005 to fund the development of two arms. The first initiative, the four-year, US $30.4 million Revolutionizing Prosthetics contract, to be completed in 2009, led by Johns Hopkins Applied Physics Laboratory in Laurel, Md., seeks a fully functioning, neurally controlled prosthetic arm using technology that is still experimental. The latter, awarded to Deka Research and Development Corp., Kamen’s New Hampshire–based medical products company (perhaps best known for the Segway), is a two-year $18.1 million 2007 effort to give amputees an advanced prosthesis that could be available immediately “for people who want to literally strap it on and go.” Kamen’s team designed the Deka arm to be controlled with noninvasive measures, using an interface a bit like a joystick.
