During my technical college days I had some time to work with Boe Bots featuring the Basic Stamp II. The Boe-Bot is a nice platform for making robots, especially for beginners. Although the kit includes all that you need to build a bot, I would recommend downloading the Basic Stamp manual as well in order to fully understand the syntax for the Stamp. Building robots is fun, but while you build them why not learn something, too?
Obtaining a Boe Bot is as easy as logging onto Parallax.com and giving them about $160 dollars. Shipping will cost you a little more.
What I like about the Boe Bot is the chassis that they provide. It gives your robot a professional look. It is also a great platform to experiment on. Adding new sensors is plug and play with the Stamp’s built on breadboard.
The downside to the Boe Bot is when you want to mount sensors to the chassis. There were not enough holes with the correct spacing to add things like Ping))) and other servos. The other problem that I had was using analog to digital conversions. With the Stamp, you must use RC time constants. This is a slightly different approach than what I am used to with Picaxe and Microchip processors.
Overall, the Boe Bot is a great platform for building bots. If you are a beginner then you won’t have any problems picking it up. If you are migrating from a different programming platform, you may have some things to get used to.
