LIVE Robot Marathon!

LIVE robot marathon! via CNN

Five robots are racing around a room in Osaka, Japan, in what organizers call the world’s first robot marathon. The robots, entered by companies and universities, will complete a 26.2-mile marathon course by making 423 circuits of a track in a room in Osaka, CNET reports. Robots that fall over will have to get back up on their own, but human pit crews can recharge batteries, according to CNET. Toughness rather than speed will determine a winner among the foot-tall robots, the report says. The event, dubbed Robomarafull, is organized by robot maker Vstone and local government officials.

Sony’s War on Makers, Hackers, and Innovators

01 Sonywar

MAKE Magazine takes a look at Sony’s history of suing makers, hackers and innovators. Over the last decade Sony has been targeting legitimate innovation, hobbyists, and competition. From picking on people who want to program their robot dogs to dance to suing people who want to run their own software on something they bought. Sony has made so many mistakes with technology choices (Memory Stick, Magic Gate, UMD!), perhaps they’ll end themselves soon enough, but until then MAKE is keeping score on Sony’s all our war on tinkerers.

The Ravenna Ultra-Low-Altitude Vehicle: A Rocketship Treehouse

The Ravenna Ultra-Low-Altitude Vehicle: A Rocketship Treehouse – the makers write -

Rarely does building a treehouse require welding, grinding, painting, riveting, bending, crimping, plumbing, brazing, laser cutting, sound design, printed circuit board fabrication, thousands of lines of C code, distributed network protocols, sewing and embroidery.

Ours did.

The RULAV is a hexagonal capsule, 7.5 feet (2.3 meters) high, atop a tripod 7.5 feet (2.3 meters) high, for an overall height of about 15 feet (4.6 meters). It is about 6.5 feet (2 meters) across at its widest point. The frame is welded mild steel with riveted aluminum skin. It contains nearly 800 LEDs forming dozens of numeric displays spread across 14 control panels, each with an acrylic face laser-cut and etched with labels such as “Lunar Distance” and “Hydraulic Pressure”. The pilot controls the rocket using a joystick and panels full of working switches, knobs and buttons. Underneath the capsule are three “thrusters” that shoot plumes of water and compressed air under the control of the pilot’s joystick, simulating real positioning thrusters. Takeoff and docking sequences are augmented by a paint-shaker that simulates the vibration of a rocket engine. Sound effects complete the illusion, with a powered subwoofer that gives the rocket a satisfying rumble.

The Lost Soviet Particle Accelerator

Whoa!

Photos via EnglishRussia, text from Discovery.com:

Last September, work began on a new particle accelerator in the small Russian town of Dubna, just outside of Moscow, slated for completion in 2016. Dubbed NIKA, it is intended to complement Switzerland’s Large Hadron Collider — which aims to discover more subatomic particles, most notably the Higgs boson — to investigate the process by which such particles first appeared by recreating the conditions of the Big Bang.

With so many eyes on the LHC these days, most news outlets missed that announcement. Even less well-known is the fact that that back in the late 1980s, the USSR started building what would have been the largest particle accelerator in the world in a town called Protvino.

The proton accelerator was known by its Russian acronym, UNK, and was the brainchild of scientists at Russia’s Institute for High Energy Physics.

While some progress had been made by 1996, the collapse of the Soviet Union and subsequent economic difficulties put the kibosh on the collider, thanks to funding cuts.

Today, the site is largely deserted, and it costs Russia roughly 80 million rubles ($2.7 million) a year to keep it pumped dry of ground water. It has also become something of a “tourist spot” for self-proclaimed urban explorers. That’s where this impressive collection of photographs were taken, a striking testament to what might have been.

Tools of Tradecraft: The CIA’s Historic Spy Kit

Cia-Spyware Belly-Buster-Hand-Crank

Tools of Tradecraft: The CIA’s Historic Spy Kit @ Wired.com

“Belly Buster” Hand-Crank Audio Drill – The CIA used the “Belly Buster” drill during the late 1950s and early 1960s to drill holes into masonry in order to implant listening devices. After assembly, the base of the drill was held firmly against the stomach, while the handle was cranked manually. The kit came with several drill bits and accessories.

Whenever James Bond needed a nifty device to snap a surreptitious surveillance picture or escape the gilded clutches of Auric Goldfinger, he could count on the ingenious minds in the Secret Service’s Q Division to devise a solution. Real-world Bonds working for the U.S. Central Intelligence Agency, and its precursor the Office of Strategic Services, could turn to the Office of Research and Development for similar tradecraft tools.

From mosquito drones to couture cameras, the CIA had its agents’ needs covered. Some of these devices are now displayed in the CIA’s museum, located at the agency’s Langley, Virginia, headquarters.

Shuttle Discovery scheduled for its last flight

Shuttle Discovery scheduled for its last flight @ CNN.com

Space shuttle Discovery is set to launch Thursday from Cape Canaveral, Florida, for its final flight, ending nearly three decades of space travel.

The six-member crew will deliver a storage module, a science rig and spare parts to the international space station during its 11-day mission.

Originally scheduled for November, Discovery’s launch was delayed because of repairs to the external tank’s support beams.

NASA, which is winding down the shuttle program, announced the February 24 launch a few weeks ago. It will be Discovery’s 39th voyage.

Moar Stochastic Robots

This video is both convoluted and funny (all those bots running into each other), but it demonstrates a cool idea. The purpose of the experiment is to quantify the coupling and uncoupling of stochastic robot systems, and create a mathematical model. It’s a neat approach to modeling such a system, and one I haven’t seen before. It also demonstrates, albeit in a simple way, one of my favorite robotics concepts: stochastic assembly. I’ve written about stochastic robots before:

Each of the little blocks represents a piece of “programmable” (or “smart”) matter. Very similar to the way complete DNA exists in every cell of your body, each of these blocks is programmed with the final shape — the ultimate goal of the assembly process. This is where the “robotic” comes in: each block is a robot, or at least a robotic element — it is programmed to perform a certain task (i.e. to assemble into a specific shape).

The blocks are placed in a “stochastic” environment: a tank of water (or air), for example, with random turbulent currents swirling around inside it. The blocks ride these currents into proximity with one another, and if they a) detect an adjacent block in the right orientation and, b) determine it is beneficial to the final construction, they connect to one another to form a subshape.

What I like most about the concept is that it closely mirrors the process of stem cells and DNA to build a final organism. Further, I think that the idea of self-assembly is critical to the future of robotics and technology — think space craft which assemble themselves in orbit, or nano-bots that enter the bloodstream and assemble into a stent or perhaps even a pacemaker. As Evan Ackerman at IEEE Spectrum puts it:

One application for these types of robots might be in the medical field, where building a robot inside someone’s body could prove to be much more effective than building one outside. All you have to do is inject a bunch of little modules into the bloodstream, they’d randomly whirl about and run into each other and grab on where appropriate, and in a little bit you’d have your robot. You could even program the modules not to assemble themselves until they reached a certain place in the body, and while such precision might take a while (or a whole bunch of injections), the potential is there for extremely precise treatments and repairs.

So what’s up with the word “stochastic” — why not just call them “random”?

Well, firstly: in engineering and science, the word stochastic is generally used to imply a non-deterministic system. In a deterministic robot system, for example, a robot would go from A to B to C. In a non-deterministic (stochastic) system, the robot could start at A, and then go to B or C, and from there it could go back to A, or to B or C (depending on the last decision made). The starting point is the same, but the outcome can be different each time. Designing a system for these conditions means that you have to sort of assume all states are possible at once, though the possibility is often weighted by probability.

Secondly, and more importantly: nobody is going to give you a grant to build and study “random robots” — not nearly impressive-sounding enough. :)

Look, Dad—They print wires now!

Pt 10814

Scientific American. Issue: Dec, 1954

Very thin copper—called “Electro-Sheet”—is bonded to a plastic laminate panel. On this copper sheet you print the wiring circuit you want with an ink that resists acid. Then you etch away the unwanted metal, leaving the pattern intact. This type of circuit is far superior to wires. It is accurate, compact and stable. Next you snap-fasten tube sockets and other parts in place and dip-solder the connections. To make a hundred electrical connections this way takes only a few seconds.

With printed wiring and other devices—such as transistors—electronic experts are concocting match-box-size hearing aids, vest pocket radios, more compact TV sets and portable electronic “brains.” They are speeding up the production of precision instruments vital in the operation of aircraft and control of guided missiles.
