Experimental Robotic Platform

ERP_Robogames09_awards

Introducing ERP: Experimental Robotic Platform. This is an open source, modular robotics platform that, as you can see above, didn’t fair too poorly in the Robogames 2009. [John] has been working on this platform for roughly 2 years and states that it will never be “finished”. It is a development platform, and is always changing and being updated.  You can follow along on the project page to see the major design changes as they happen, such as the wheel suspension system cut from a single piece of plastic. All of the pieces, schematics, and software are available for download. Be sure to scroll down and see ERP’s reaction to some of crabfu’s inventions.

Little Walker

This little walking robot caught our eye. We’ve seen tons of 4 legged bots, but the design on this probably took more effort than the electronics. The design is radially symmetrical, it can walk in any direction, turn in place, and even walk upside down. The electronics weren’t forgotten though. This little bugger manages to pull a half our of use out of each battery charging. It communicates wirelessly with a custom dual Wiimote Nunchuck setup via XBEE modules. You can find much more technical details in the captions of the pictures. We’re not positive what processing power is hidden in the bot itself, but we know there’s an Arduino in one of the nunchucks. This might be the brains of the operation leaving the hardware on the bot simply to control the servos. We really like the arc-reactor-esque power display.

[Jared Bouck] is on a roll this week. We just covered his Diamond thermal paste and now he’s got more for us. To celebrate the re design of his website, he has released the plans for the paintball turret. As you may recall, we absolutely loved this design when he originally showed it to us. Though he has had kits available for a while, he has finally put the plans up for download. You can cut your own parts and build it yourself. He mentions that version 2 is coming shortly, we wait with bated breath.

Amazing Robot Dexterity

Ishikawa Komuro Laboratories are doing some amazing stuff with robots right now. The video above starts out looking like a clumsy and somewhat failed attempt at dribbling a ping pong ball. Once it goes into slow motion however, we see the true action. This robot is dribbling that ball amazingly. Utilizing 1000 FPS cameras, it readjusts and hits the ball on every bounce. As the ball drifts out of the reach of the bot, suddenly we are struck with the lifelike motion.  Personification can be a fleeting thing, appearing so strongly as the little bot tries in vain to reach for that ball, then disappearing again an instant later. If you really want to see some personification worthy of the crab fu challenge, check out their tool manipulation by a multi fingered hand video.

Thin Client As Robot Platform

geode

[Extra Ketchup] has a couple Neoware thin clients and thought they would make a good robotics platform. It’s a Geode based board that came with Windows CE. He built a small Gentoo system to fit on the 130MB solid state drive. He likes the idea of using it as a platform because the board has serial, parallel, and USB support. The best part is shown above; it can run off of just 4 AA’s.

Pet-squirting Waterwall

waterwall

Sometimes, pets need to be trained to stay away from certain things. Over at sump.org, his cats needed to be kept out of his room. He used their natural fear of water by creating the waterwall, a motion-sensing device that sprays water. The project is incredibly simple and uses very few components. It is based around an IR intrusion detector and a windshield washer pump. Although that worked well enough, he also hooked it up to his computer via the parallel port so that he could take pictures as the cats (or people) are sprayed. Although the project is old, it shows how few components are really needed to achieve this kind of behavior.

Snake Bot

sb head (Custom)

[Husstech] wrote in to share his Snake Bot with us. Initially inspired by this post about SickSack, a snake bot, he set out to build his own version. While the concept and even the design aren’t particularly new or groundbreaking, he is very thorough in his documentation. Since this was a project for school, the PDF of his project includes research, schematics, cost breakdowns, and results. We really like the camera and head design, it looks very insect like. You can see a video of the final version being shown off after the break, or you can see an earlier version that is decidedly more phallic.
