[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.

Autonomous Tank Terrorizing Campus

tank

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 Files For Bankruptcy

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.

When [Epokh] sent in this Wii controlled segway style bot, we remembered a post a few months ago where someone made a balancing bot, but hadn’t completed the Wii code. Well, [Epokh] is going to show you how to implement the Wii controls with the Lego NXT system. He’s found the links to all the software you need and broken down the configuration step by step. He’s been busy lately, let’s hope he keeps it up.

Bioloid Hacking With Johnny Lee

bioloid

Though we usually think of Wii projects when we see him, [Johnny Lee] is showing us some Bioloid fun. He’s decided to pick one up to play with, wanting to write his own control programs for it. Unfortunately what he found was that it doesn’t do wireless communication for control. Even after installing a bluetooth module, he found it was only used to trigger different predetermined motions. After some research, he found how to connect the bluetooth module to the main PC link which allows him direct control of the Bioloid via the PC. Unfortunately, the communication speed leaves a lot to be desired, but it’s a good start. We’ll keep our eye on this one.

Fast Little Hexapods

We’ve posted many many times about hexapods. One of the most common comments, aside from how creepy they are, is about their speed. Hexapods are generally pretty slow. These little bots are quite a bit different though. The Sprawl and iSprawl, are anything but slow. Using a hybrid leg mechanism that aims its piston like “toes”, they mimic the motion of cockroaches. The video shows the speed can be pretty quick, especially the iSprawl in the second half. The leg mechanism the Sprawl is air powered, while the iSprawl uses a push/pull cable transmission system. As pointed out at BotJunkie, it’s nice for the “i” in iSprawl to actually mean something. It stands for “independent”.

Felix’s Machines

Ok, we know you’re going to get mad, there’s virtually no information on the technical side. But the music was so pleasant, and that’s rare. There’s an interview with Felix, the creator, where he discusses his goals and ideas behind the project. We prefer just to sit and watch though. If you want to make something similar, there were some technical details on a mechanical drum recently.
