I-Swarm Robot Update

Back in October we reported on the I-Swarm robotics project. [Travis] sent us some more information. These tiny robots are programmed optically and are able to respond to programming commands via an infrared signal. Locomotion is facilitated with piezoelectric actuators and the power to the units provided through a solar cell. It is not clear that this project is still ongoing as the I-Swarm web page lists a project termination date of 6/31/2008. That being said, the video embedded after the break was posted two days ago showing swarm movement and detailing the programming, testing, and hardware specifics.

Internet Enabled Furby

[edwindertien] sent us his project to connect a Furby to the internet. The original Furby controller was replaced with an Arduino which in turn was given ethernet connectivity via a LANTRONIX XPort serial ethernet module. This assigns the Furby an IP address which can then be accessed through a script or via a web interface. Now we want to see someone combine this idea with the arduino that sings “Daisy Bell” to make the ultimate in creepy new email notifiers.

Lego IPod Hacking Robot

The Linux4nano project has been working to port the Linux kernel onto the iPod Nano along with other iPods in general. Although the iPodLinux project has had luck with some older iPods, newer models protect firmware updates with encryption. One of the ways they plan on running code on the device is through a vulnerability in the notes program; it causes the processor to jump to a specific instruction and execute arbitrary code. To take advantage of this, they first need to figure out where their injected code ends up in the memory. Currently, they are testing every memory location by painstakingly loading in a bogus note and recording its effect. Each note takes about a minute to test and they have tens of thousands of addresses to check over several devices.

Tiny Light-seeking Robots

[Alex] continues to delight us with his projects. His third-generation tiny Braitenberg vehicle, a light seeking robot, is a big improvement over its predecessor, the mini Braitenberg vehicle. He’s moved from an Arduino based design to using the AVR ATtiny25v, replaced the breadboard with a PCB, and reduced the parts count. We think it was a great idea to use shrink tubing to shield the back of the photo-resistors from ambient light. Don’t miss the video of these little guys chasing a flashlight beam after the break.

Phasma Insectoid

When we saw the video of the Phasma insectoid robot above, we immediately thought of the iSprawl. After checking out their site, it turns out that the two are connected in some way, we’re not sure how, maybe just inspiration. The Phasma gives us a little more insight into the construction of the bot. The photos are highly detailed so you can see how the drive works, using the sliding cables to extend the “feet”. It seems quite agile in the video. The drive system, working off of a single cam seems like it would be easy to convert to steam. We would love to see that.

SpiderBot Emulates Spider-man

Spiderbot moves with four magnetic grapplers that it can launch, detach, and aim according to it’s path planning algorithm. While the robot is definitely not a final product and is quite a bit away from moving with the same grace and speed as our friendly neighborhood Spider-Man, it is definitely one of the more interesting locomotion experiments out there. The video has some nice slow motion footage of the main mechanisms as well as screen captures of the path planning.

LEGO Mindstorms Sudoku Solver

Swedish hacker [Hans Andersson] is no stranger to puzzle-solving robots. His prior work, A Rubik’s cube-solving robot called Tilted Twister, made waves through the internet last year. [Hans’] latest project only has to work in two dimensions, but is no less clever. This new robot, built around the LEGO Mindstorms NXT system, “reads” a printed sudoku page, solves the puzzle, then fills out the solution right on the same page, confidently and in ink. It’s a well-rounded project that brings together an unexpected image scanner, image processing algorithms, and precise motor control, all using standard NXT elements.

The building instructions have not yet been posted, but if the video above and the directions for his prior ’bot are any indication, then we’re in for a treat; he simply has a knack for explaining things concisely and with visual clarity. The source code and the detailed PDF diagrams for Tilted Twister are as gorgeous as his new robot’s penmanship.
