time has not been on my side (moving) so I moved the stamp onto the bot for now. really want to use the PIC mostly due to the cost factor.

anywho have the sonar sensor working pretty well. did a simple algorithm to just drive around the apartment in any direction where it could (more than 2 feet in a direction) which was kind of neat since the apartment is filled with boxes (did i mention that i hate moving).

the tracked vehicle is kind of neat but i'm thinking the next bot will have wheels or legs.

received a devantech sonar module srf04. expectations weren't to high but i have been very pleased with how well this thing works. prototyped it with a stamp and got great results. mounted on the tankbot and have to get some code into the bot's PIC. going to use the ccp module on the PIC to learn something new.

Put together a servo tankbot from budgetrobotics.com. Added bump switches and run it all with a pic 16f627 using C.

Took a bit to get used to interfacing with hardware in C. Time etc. isn't as simple as my previous experience (BS 2SX). But a lot more flexible.

Researching two or three things right now before the next step...

Need more sensors... SharpIR or Devantech Sonar? Haven't decided yet. Would like to dedicate one PIC to driving servos, one to brains and one to sensors and let them all communicate.

That brings up the second issue. How to let the pics communicate with each other. Am I being silly trying to put more than one chip on a bot?
