Swarming Robot Ants

October 29, 2008 by Kimberly Lau 5 Comments

European researchers in the I-SWARM project are hard at work developing small, autonomous robots that can work together and communicate to perform different functions. They successfully built two types of robots: the I-SWARM, and the Jasmine robots. The I-SWARM robots are three millimeters in size, are powered by a solar cell, and move by vibration. The Jasmine robots are the size of two-Euro coins, have small wheels, and are powered by battery. These tiny robots have several advantages over their bulky predecessors, such as high redundancy, greater flexibility, and the ability to manage tough terrain. They could even be used to repair larger robots. They also come with distinct challenges. Because of their minuscule size, programming memory is necessarily limited, and the team had to come up with special algorithms to manage and control the machines. Though they haven’t been able to meet their goal of making a thousand of them, the researchers are hopeful and confident about their abilities to mass produce the robots cheaply.

Autonomous Wall-E

October 28, 2008 by Caleb Kraft 25 Comments

[djsures] went crazy on his Interactive Wall-E toy. Wall-E just didn’t have enough bounce in his step, so [djsures] decided to give him an overhaul. He went through the entire robot and replaced most of the joints with servos, giving much more control and adding head tilt. All of this was wired to a microcontroller housed in Wall-E’s body. The distance sensor was mounted in Wall-E’s neck, so when he turns his head, he’s actually surveying his surroundings. Check out the video after the break.

Rovio Teardown

October 20, 2008 by Caleb Kraft 5 Comments

[Del] sent us what might be the first in an expected plethora of hacks on the Wowee Rovio. He was annoyed by the poor lighting for Rovio’s camera so he cracked it open and started hacking. He found there was just enough space for a couple LEDs in the head. The most difficult part of this was apparently running the wires for power into the main body of the rovio. He said it took him around 30 minutes just to snake the wires through the neck. The final result is best seen in the comparison pictures of rovio looking at Wall-E.

IPhone Controlled R/C Car

Is controlling an R/C car with its own remote too mundane for you? Do you feel the need to involve a web server and an iPhone in the process? This project might just be perfect for you. By connecting the R/C controller to a microcontroller board, and feeding it signals via a website from your iPhone, you can control the car as if you had the original controller in your hand. In case you missed it, he’s lugging a laptop, a circuit board, and the original controller along with him. They do make a few improvements though, such as speed control by using pulse width modulation. I guess that makes up for having to lug the computer around too.

Cambridge Autonomous Underwater Vehicle

October 15, 2008 by Caleb Kraft 11 Comments

The Cambridge Autonomous Underwater Vehicle, built for the SAUC-E Challenge, is a fantastic example of UAV construction. The competition is to build a UAV that can complete an underwater assault course. This baby has a full computer inside it, based off of the worlds smallest full featured x86 motherboard, the Pico-Itx. It has a 1GHz EPIA PX 1000 Board, 1 GB of RAM, Wireless Network capabilities and runs Ubuntu server 8.04.

The CUAV suffered from leaks which ultimately cost it the competition, but the information on the build is fantastic. They have detailed pages upon pages of information about the Mechanical, Electronic, and Software aspects of the design. They even went back in and added notes from what they learned during the competition. The project is also outlined in much shorter form on the mini-itx website.

Playstation Tank Controller

October 12, 2008 by Eliot 6 Comments

[stuart] wanted a more intuitive way to control his rover platform than the software solution he had been using. He settled on using a Playstation controller with an AVR to operate the rover wirelessly. He found a couple references for talking to the controller using SPI on a PIC and adapted that for his ATMega88. The code is available on his site. He removed the rumble motors from the controller and stuffed the chip plus the transmitter package inside. The Linx TX/RX pair are mounted to pluggable boards so he can use them on other projects. A video of the tank in motion is after the jump. Continue reading “Playstation Tank Controller” →

Inexpensive Powerful Router Based Robot

October 7, 2008 by Caleb Kraft 10 Comments

[Andrey Mikhalchuk] Has posted some great instructions on how to build an inexpensive router based robot. Starting with a Linksys WRT54GL, he takes us through the process of disassembling and modifying it to directly control servos. He has put together a custom version of OpenWRT Linux that you can download from his site. After testing to make sure everything is functional, he goes through a quick and dirty chassis build. As you can see from the picture above, there are lot of household items thrown in there such as rubber bands and zip ties. After adding a camera mounted on two servos for x y movement, he fine tunes it and lets it go.

This project looks fairly simple, cheap, and fun. It may look familiar as it is very similar to our Wifi Robot post from August.
