[Colt45] shows us some pictures of his Rovio fire extinguisher mod. Being a fan of model building, he built a new shell for the Rovio and mounted a halon distribution system to the top of it. He says he loaded some custom software for identifying and extinguishing flames, which he’ll upload eventually. We really wish we knew more, or at least had a video of it working. We’re a little bit surprised we haven’t seen more done with these things.
[Thanks Robert]

This art display system was created by [Peter Sand]. It is called Plant Fasting and is comprised of a giant robot with interchangeable tools for various gardening tasks. Though the system is mostly automated, it can be controlled via a game pad. It has an Arduino as its brain and it looks like he’s done a completely custom setup for powering the interchangeable pieces.

Festo, people who brought us the Manta Ray blimp are back with giant flying penguins. Actually, there’s lots of cool stuff in this video. The flying penguins are nice, but the swimming versions are amazingly believable. They need to sell these as pool toys. There’s also an interactive wall sculpture and a dangling grabby hand that apparently solves the age old riddle; “How many weird dangly grabby things does it take to randomly place several light bulbs in different sockets?”. The answer is, one. Just like last time, they’re sharing some details in PDF form for both the air penguins and the aqua penguins.

[Andy] wrote in to show us how he hacked his Pleo to be controlled by a Wii Nunchuck. He has installed Xbee units for the communication as well as written a “skit” that allows the Pleo to just stand there and wait for commands. He is using an Arduino to interpret the Nunchuck input and send it to the Pleo. It’s a pretty cool proof of concept, but the response time is pretty slow. This might be due to the Arduino’s slower serial communication rate. Yes, we said you might want to refrain from hacking them, due to their impending extinction, but did you expect us to stick to that? If you’re going to dig into one, you may also be interested in how to hack the Pleo for face recognition and remote control.

[Travis7s] has built this giant Nerf Tank. Featuring Radio controls, a web cam, laser sights, and the ability to play music, this thing is pretty awesome. He’s using the Nerf Vulcan rifle, temporarily modified with a servo for remote firing. This thing is pretty huge, as you can see from the video, it sits about as high as the seat cushions of the chairs in his house. The sound system is an amplifier and some speakers hooked up to an iPod. This thing could use a nice coat of paint to make it a little more menacing and a little less Nerf. What it really needs though, is the ability to play sounds from a sound board. Imagine the Imperial March as it enters a room, or maybe a sound board with appropriate insults and phrases for the onslaught.
As a senior design project for ECE4007, [Nate], [An], [Chris], and [Wink] built an autonomous toy tank. It is using a Panasonic IR motion sensor to find targets, then once it’s facing the target it switches to visual motion tracking through it’s web cam. If it can get close enough, it will stop and begin rotating the turret for more accuracy. Finally it fires a pellet. It’s brains are an ICOP technology eBox-2300 running windows CE. All of the programming is available on the site, as well as a breakdown of the various sensors and hardware. As you can see in the video after the break, it does a decent job. Given some more time, we’re sure they could speed up the target acquisition process. Maybe we should add a category for Georgia Tech final projects.
Ugobe has officially filed bankruptcy. This is bad news for Pleo. That lovable little dino bot is no longer being produced. If you’ve got one you might want to refrain from hacking, just in case it’s worth something one day. As the point out at Engadget, another toy company might buy up the rights, but we doubt it. At roughly $250 per unit, these things probably weren’t flying off the shelves.
