Robot Programs

Hi Guys,
········ I'm pretty much need help or someone to point me in the direction on how to·program the Basic Stamp 2 chip to learn or record data. I'm currently· building a robot to run through a micro mouse maze and programming it to learn to run the first run and having it learn the wrong turns. When it run the second time it should be able to run in the right path and not take any wrong turns after learning in the 1st run. Can someone point me in the direction on how to program the Basic Stamp 2 chip. Thanks.

Mostly, it will take a lot of hard word. The BS2 is really that well suited to AI (which is what you're looking for), so you'll need to find a way around it. My recomendation is that it recordes (in EEPROM, maybe) all the choices it makes, and if it makes a wrong choice it backs up and erases until it gets to the next choice, and tries the alternative. For values stored in the EEPROM, you could have

0 = unused
1 = left
2 = forward
3 = right
4 = backward

Then, you'll end up with a list of choices: 242452321132131. The hard part will be detecting when you can make a choice.

The Robotics with the Boe-Bot book includes many examples with writing and reading from EEPROM, and it's a free download. Even if you are not using a Boe-Bot, the example code is explained so completely you can port it to other kinds of motor control and systems. You should really start with the basic stuff, then build it one step at a time. Don't try to throw together a whole maze-solving robot until you've achieved basic movement.

Thanks. You guys are very helpful and at least I'm in the right direction.

The BASIC Stamp I and II modules will work in 0° to 70° C temperatures with up to 70%, non-condensing
humidity. While the modules may continue to function outside these ranges, it is not guaranteed or
