Hi all, I'm currently migrating to the newest release of BotsInc environment the second microworld that was initially planned to be described in the book.
For now I published on my web site http://smallwiki.unibe.ch/botsinc/ download/ an old image that you can use with the current environment (just drop the .image file on the squeak executable). Pay attention that this is an old version (prior to the distribution 02-2005). This old image that works on any platforms. I also released some advanced drafts of chapters describing this microworld and also some really fun chapters for BotsInc. I hope to find some money to ask a professional to proofread them. For now they are given for free as they are. I plan to give them for free in the future too.

BotsInc is the environment of the book Squeak: Learn Programming with Robots I wrote over the last 4 years. With Bots Inc you will learn how to program robots in an interactive environment. Bots Inc proposes three teaching approaches: direct command of robots, scripting robots and programming robots. The book contains 24 chapters going step by step over topics with a lot of examples. Bots Inc is fun but it is not a toy, it teaches you 100% real programming. Bots Inc is built on top of the rich open-source multimedia Squeak environment that you can also discover.
