LEGO Chooses Mindstorms Community Developers?

Posted on February 28th, 2006 by admin in Latest News
ImageJason Striegel over at BlogCadre, has given us a the first news in a while about LEGO’s Mindstorms Developer Program According to Striegel, LEGO sent out a email that reads:

Thank you very much for your interest in participating in the LEGO(r) MINDSTORMS(tm) Developer Program. We are very sorry but unfortunately you have not been selected to take part in the Program. Over 9000 fans sent in their applications and it was extremely difficult selecting 100 people only.

As of yet, there is no other news of others receiving this email. Stay tuned.

Update: Striegel also pointed out the URL for requesting notification when NXT is ready for pre-order.

Ticks beware: RC Truck Hacked for Pest Control

Posted on February 28th, 2006 by admin in Latest News
ImageTicks are a health hazard to humans and pets alike. Yet few spray pesticides indiscriminately in tick-infested areas, primarily out of concerns over environment and cost.

Justin Woulfe and his fellow students at the Virginia Military Institute came up with a novel solution. They hacked an RC truck, upgraded the drive motor to 11W, the batteries to 12V NiMH, and added an Atmel AVR ATmega8. The resulting robot, dubbed Tick Rover, was then sent out to comb the lawn.

The ticks that jumped onto the comb and were exposed to localized Permethrin, zapping the insect without leaving any chemicals behind. Environmentally it is much safer. But what about the cost?

At $500 a pop, Woulfe doesn’t expect consumers to purchase the machine. But pesticide companies who invest in it could charge less for running the robot — about $75 per acre — than they now charge for spraying, which costs about $85 per yard.

Not too bad for a first generation prototype. The IEEE thought so, too, and rewarded the effort.

The students earned an undergraduate research grant to fund development, and wrote a paper on the device which won first place in the Virginia Mountain Section of the annual IEEE Student Papers Contest, and then won second place in the IEEE Region 3 contest — one of the 6 regions in the country.

For more information, see the first and second field test results, Woulfe’s paper, and this article on Wired.

The NXT STEP – Lego Mindstorms NXT Blog

Posted on February 27th, 2006 by admin in Hobbyiest
ImageRecently, Jim, over at The NXT Step blog let me know he’d added GoRobotics.net to his blogroll. Since we don’t currently have a blogroll, the "nxt" best thing is to give him a shout-out in a post! The NXT Step is now on my feed list. It’s a great site for information about about LEGO’s up-and-coming Mindstorms NXT kit.

Jim’s blog also alerted me to another great NXT site by Filip Verhaeghe, BNXT.

Great sites, Jim and Filip.

Monday Housecleaning – Load of Links

Posted on February 27th, 2006 by admin in Latest News
Well, February is almost over and I feel like doing some house-cleaning. So, here goes.

First up is RoboSapiens, a "docu sci-fi feature film". It, "is a character based feature documentary on the robo-adventures of Mark Tilden, Canada’s most notorious and internationally famous robot scientist."

And speaking of Tilden, here’s a 5 page interview with him. In it he talks some about WowWee’s 2006 robot lineup.

Next is more on the SeaBED AUV that we recently blogged about having explored an ancient shipwreck.

Did you know that the Pentagon, "has set up a special unit complete with robots to conduct forensic tests in the event of a nuclear attack on the US"? Now you do.

And lest ye haven’t seen it already, how about the giant, car-lifting, snow rescue robot from our buddies at Tmsuk? Or these creepy moving mannequins?

And those of you that are suckers for LEDs like I am. Here’s three nifty links.

And last, but not least, finally some Roomba hacking instructions, complete with pictures and schematics!

InTouch RP-6 Medical Telepresence Robot

Posted on February 27th, 2006 by admin in Latest News
ImagePopulations in developing nations are aging, putting increased demands on healthcare systems. This has been said so much as to almost become cliché. The fact is that healthcare is in need of automation technology, and robotics companies are answering the call.

One such company is InTouch Technologies. It has only been around for a few years and has yet to complete its website. Still, InTouch has been making waves by fulfilling a vital need. Its product, RP-6, let’s doctors visit patients remotely.

The RP-6 is InTouch’s sixth generation remote presence droid. Controlled by a webcam and joystick, it requires broadband access both at the hospital and at the doctor’s desk. Commands are then sent from a server to the RP-6 over WiFi. This communication link is reliable and impressive enough to earn Cisco’s Growing with Technology Awards.

The droid itself stands 5 feet, 5 inches. Having wheels limits the RP-6 to flat surfaces, though the drive system is reasonably efficient. It manages to squeeze an 8-hour runtime from a single charge.

RP-6’s head is a combination LCD panel and video camera. The head can tilt and pan, at a range of 116° and 170° respectively. Once pointed at the object of interest, the doctor can look closely by using the camera’s 12X optical zoom.

Hospitals can rent the RP-6 for $4,000 a month, or buy it outright from InTouch for $120,000. Last year, my local Detroit Medical Center picked up ten of these units. This month another unit found a home at Baltimore’s Sinai Hospital. This is a robot on the move.

Meet Cyberstein

Posted on February 25th, 2006 by admin in Latest News
Image Nik Fielding is one busy fellow. He’s worked up several robots such as an ED-209 and three humanoids. These are X-BOT, VOR, and Cyberstein. With these last two, Nik Fielding does shows and events (click here to see videos).

The robot Cyberstein was last seen at the home of the future show put on by Omniyat Properties. Standing 8’ tall and with a look reminiscent of the Terminator, Cyberstein isn’t exactly the ideal image of a domestic robot. Unless, perhaps, as a home security droid.

These are show robots. That is, Cyberstein is more like an animatronic suit than an autonomous brute. Nevertheless, it is well worth the time to watch the videos and marvel over Fielding’s craftsmanship.

The Mysterious Creator of the Predator Drone

Posted on February 24th, 2006 by admin in Military
ImageHave you ever wondered who created the Predator drone? If so, then you’ll want to check out this piece by Red Herring about General Atomics Aeronautical Systems (GAAS), the creator of the Predator, and it’s plans for the future (including Predator B and C!). The company is privately owned by a 55 year old conglomerate, and is highly secretive. The good news for them is that the Air Force plans to buy as many Predator drones as GAAS can build. Not something you hear every day.

There’s also some juicy information on the new Predator, the Predator B:

While the Predator and the Warrior have wingspans of around 55 feet, fly at altitudes of 25,000 feet and 29,000 feet, respectively, and can carry payloads of around 400 pounds, the Predator B is the super weapon. With a wingspan of 66 feet and a length of 36 feet it can fly for more than 30 hours at 50,000 feet

Right now GAAS is looking pretty good. But, will they be able to keep it up as the Pentagon decreases spending? I guess we’ll have to see. But, in the meantime the Predator will be putting some serious hurttin’ on baddies everywhere.

New Ultrasonic Sensor for Hobbiests

Posted on February 24th, 2006 by admin in Hobbyiest
ImageLook out Devantech, there’s a new kid on the proverbial block, the robotics-block, that is. While the ultrasonic sensor line from Devantech has turned into a staple for many hobby robots, it looks like there might be another viable contender. Check out the Ultrasonic Range Finder from Maxbotix, which is listed for $24. A FAQ and datasheet on the sensor are available on Maxbotix’s website. The specs on the device say it can range from 0 to 6.45 meters (0 – 256 inches), and outputs in either serial, analog, or PWM signals.

PS. Maxbotix or Devantech, if you’re listening, how about sending some of your stuff our way for reviews?

More On The Lockheed Martin Sub Launched Robotic Plane

Posted on February 23rd, 2006 by admin in Military
ImageRemember the sub-launched robotic plane we talked about before? Well, here’s some more information on it, courtesy of Popular Science. The plane will be released from a Trident missile tube on an Ohio-class U.S. submarine, surface, then take off.

"The [missile] tubes are as long as a semi trailer but about seven feet wide—not exactly airplane-shaped. The Cormorant has to be strong enough to withstand the pressure 150 feet underwater—enough to cave in hatches on a normal aircraft—but light enough to fly."

The plane, dubbed the "Cormorant" will have a 500 mile range. Once the Cormorant’s mission is finished, it will then return to the designated return point, and be retrieved by a unmanned vehicle, which will return the Cormorant to the sub. The reason for this is to help keep the location of the submarine secret.

The plane is made out of titanium for strength and filled will foam to help it survive the pressure from being released150ft under the water. It will be equipped with weapon systems or used for surveillance. DARPA will be conducting tests on the Cormorant until September, when it will decide whether or not to continue the project.

Robots Delivering and Pouring Beer

Posted on February 23rd, 2006 by admin in Latest News
Image
Asahi Breweries
Getting a robot to fetch your beer has about as long a history as getting your robot to vacuum your floor. At any given time, Universities across the globe are hard at work on this task. There is the University of Florida’s Koolio, for example, or Duke’s Kegbot. Comercial ventures, like Asahi Breweries, are also entering the fray. The move is on for beverage delivery robots.

Aside from cost, the main difficulty with the current robots is that last vital hop, from keg to glass. Thomas Weber handed this assignment to science students at the University of Darmstadt. Pour the beer, make it pretty, and do it cheaply. Hermann, the student’s prototype, will supposedly pull a pint in under two minutes at a cost of less than £50 pounds or $100 dollars.

Cornell Research into Dragonfly Micro-Air Vehicle (MAV)

Posted on February 22nd, 2006 by admin in Science
Image From houseflies to honeybees, insects inspire us with flight skills just beyond the grasp of our technology. Z. Jane Wang, a professor at Cornell University, is working to close this gap between inspiration and implementation. Wang’s recent work is on dragonflies, and here she has found some peculiarities.


For example, "an airfoil uses aerodynamic lift to carry its weight. But the dragonfly uses a lot of aerodynamic drag to carry its weight. That is weird, because with airplanes you always think about minimizing drag. You never think about using drag."


Implementing a dragonfly MAV is still an elusive goal, hopefully made somewhat nearer by Wang’s research. The research and prior art is summarized in her recent paper, Dissecting Insect Flight. This and more can be found on her group’s website, which appropriately enough is dragonfly.tam.cornell.edu.

Volvo Working on a Vehicle for Towing Loads in California Mountains

Posted on February 21st, 2006 by admin in Latest News
If you come across any driverless Volvos towing trailers and caravans through the mountain passes of Death Valley in California, don’t panic. It is simply Volvo testing and refining their towing capacity.

Volvo developed a robot to automate the driving and minimize subjectivity. The device resembles a cross between cruise control and Stanford’s Volkswagen interface.  It steers and maneuvers the car thru several tests, including movements meant to destabilize the trailer.

Image Image Looking at the photographs, it appears that a person is still in the driver’s seat. Presumably, this fellow provides navigation and manual override. This is no DARPA entrant, yet Volvo’s device is impressive nonetheless.

Stanford Working on Vehicle to Drive Through California Traffic

Posted on February 16th, 2006 by admin in Latest News
Hot off of their historic win at the DARPA Grand Challenge 2005, Stanford’s next goal is to create a robotic car that can drive on city streets. Their current goal is to have a vehicle drive from Los Angeles to San Franciso in October of 2007. Once again, VW will be sponsoring the team, this time with a smaller vehicle, like a Pasat Wagon. The team invisions robotic cars driving commuters to and from work freeing up hundreds of man hours a year.

"The average American worker spends an hour a day in the car, being non-productive. The amount of (productivity) money lost is estimated at $61 billion a year. This is a huge opportunity. It’s going to be a multi-billion industry,"

Another benefit of such robotic cars is the added safety. If driving were 10% safer, upwards of 4,000 lives/year could be saved.

I, for one, will believe it when I see it. Sometimes I actually like driving and not having to worry about other things. Next thing you know, companies will be expecting their employees to be doing productive work during their commute instead of having some time alone – which is rare enough as it is.
