I just read an article in Linux Magazine about Linux robots (http://www.linux-magazine.com/issue/65 and http://www.linuxrobots.org). The robot is connected to a network via an onboard WLAN card. You SSH into the computer on the robot, execute some C code (which hooks into the robot's libraries called 'librobot'), and botta-boom-botta-bing -- the robot moves.
I thought it would be neat to write a layer that would translate E-Toy scripts into C in order to enable kids to control a robot from Squeak. However, I have no clue how to "export" E-Toys scripts. Maybe that is the wrong tack altogether. Perhaps all I need is a plugin or FFI that would interface with the librobot C code. Am I on the right path, or is it more complicated than that?

I think the player/stage project is much more suitable for this implementation. There were already some implementation for robot control via DEVS models at our university.

I SSH to my linux robot (over a bluetooth wireless connection) and execute Squeak code running on a gumstix, which makes the robot move...

Wow! Do you mind if I submit a link to your site on the LinuxRobot Wiki?
Do you have a rough estimate of how much this think costs to build? Is your software available for download? My goal is to take a working robot into a homeschool classroom (of about 5 or 6 kids, 7 and 8 years of age) and have them "plan the missions" as you say. I would like them to use E-Toys to script the robot's movements.

I'm already listed on http://www.linuxrobots.org/wiki/Hobbyists
Do you have a rough estimate of how much this think costs to build?
Well, it didn't cost me very much, but I already had most of the parts, including the rather expensive 3-axis digital compass, and the lathe/milling machine to shape the metal and plastic parts.
Is your software available for download?
No, not at this time. I'm still not sure where I'm going to go with it, so I don't want to release it quite yet.

You could build a much simpler robot than I have - mine is intended more for outside use, and is fairly rugged, and was designed from the outset with a bunch of components I already had. A very simple, somewhat smaller robot would be quite possible, based on one of the cheap robot bases that are available.
Check out http://www.budgetrobotics.com for a few cheap and simple robot bases designed more along the lines of what you're after. Scooterbot looks like a good example of a simple "putter around the floor" robot for educational use.
Use a controller like this: http://www.bdmicro.com/mavric-iib/ to handle the hardware interfacing, add in a gumstix connext with a CF-stix for Wifi access, and you're ready to have some serious fun.

Hi Jason,
You might be interested by the squeakbot project, which allows children to script a robot through E-toys script. The robot are made by children themselves thanks to simple low-cost I2C electronic modules interfacing the computer with the mechanical and electrical parts of the robots. The pcb (electronic schema) of the modules are available too, so you can start from this schema or buy one (contact us).
For a more precise description, see here : http://www.iutc3.unicaen.fr/serge/SqueakBot
An overview of the project is currently available (Serge, could you publish the article on the website ?)
This platform has been already tested during a summer camp, and youngs seem to like it, we plan to release the complete platform soon (probably after this summer, since we would like to test the new beta version of squeakbot during a summer camp).
Regards, Samir

Thanks John and Samir. I will look into your suggestions. My target is for the Fall Semester. So, I should be able to give updates the closer to September that we get.
