50$ robot with Arduino?
« on: January 27, 2010, 12:40:55 AM »
How hard would it be to convert the 50$ robot with rangefinder to be controlled by Arduino?  I want it to avoid things in range instead of chasing them.

Depends if you know how to program an Arduino... You should be able to use the servo library to control the servos, but I don't think there's a rangefinder library. Do you know how to wire the servos/rangefinder?

It would not be too hard (to program), even if there is no library. Just keep track of where the servo is, and do a analogRead on the pin the IR is on, and convert that to a distance (or don't convert, thats optional, if you are just interested in avoiding things). If the servo is to the left, and the voltage(ie the return of analogRead() ) goes beyond a threshold, then have your robot go right.
