Congress Talks about "Trash Robotic Router Platform". My personal project.

I wolud like to share with you, two talks that I have made this year in two national security congresses.

In both talks I present a Router based ROV [Texas Ranger] and a Fonera quadcopter [Atropos] both presented in LMR already:

Electric IMP : Easy Wifi

The Card

I was looking for a simple way to add Wifi to a robot project, when someone pointed me to Electric IMP. After reading a little about it, i decided to just order one and try it out. A few evenings of toying and I have to conclude that the IMP is a whole new type of component.

Most of this is described about in the video however this is a little more indepth and more story driven. My first 'real' project, and first post on LMR. Read more

How to build BeagleBoard based WiFi robot

Some time ago I have announced my remotely (over the Internet) controlled robot. However, there were not too much documentation and details. So with this post I would like to announce the availability of more detailed project documentation and make brief overview of some interesting aspects of the project. The whole available documentation could be found on the project Wiki.

Need Guru Help Regarding Micro-Controller + Wireless

Hello !
What is the most inexpensive, yet stable robust and relatively fast micro-controller + wireless setup?

I have been asking this question to myself for way too long... Now, I'm curious of your experiences in the different flavors available..

In my specific situation talking back and forth to a computer or laptop would be the primary objective.

RC car

Ok, so I'm working on a plan to bring my little brother's little Niko RC car (you know, these models that suddenly break down for no reason at all after three charges) back to life. The plan is:

  1. Yank out old electronics (fun job, done ^^)
  2. Test steering servo and current draw of drive motor
  3. Build new electronics

Step 2 will be done by tonight but I have a few hickups on step three.

Note to self: zipit runs linux

I just learned about a thingy called zipit. Apparently it can run a linux distro and then the world is your oyster. Click the pic.

WiFinder Robot

I'm making a WiFinder robot and I am having some trouble with my arduino code. 

I want to be able to set the robot to a wifi network and have it follow the strongest wifi signal. I plan to have edge detection for stairs and distance from wall sensing. I am having trouble finding the code to be able to get the WiFly to send its signal strength to the arduino, and then converting it to an integer. I know that the the wifly will respond to the command "show rssi" with the signal strength. please help

my code follows:

Wifi logic robot

So I was thinking, What if robots didn't do the "thinking" right there but sent it to a pc set to run the logic of the robot and then sent it back to the robot via wifi? I think it would be and faster and more powerfull then doing it on a tiny microcontroller.

Any ideas?
