My Simple Bot
This simple bot is my first larger project. I still have no clue about the fundamentals of electricity or electronics (and never soldered anything in my life till last weekend) but was fascinated by the possibilties.
After some "research" on Google and Youtube I ordered all necessary parts online - except the foamboard used for the chassis which comes from the local home improvement store.
The base is built of cutted foamboard and glued together. The motors are fixed with double sided tape, same for the servo that moved the IR sensor. As you see the breadboard is nearly empty as I decided to use the Arduino motor shield for my first experiments.
The robot is powered by 6x1,5V AA batteries and moves quite slowly. The IR sensors is moved right/left while averaging the mean distance out of 3 measures. If a certain minimal distance is reached the bot stops, looks left and right to check the free distance availabe, turns into the best direction and goes on.
All functionality fits into a few lines sketch because I did no calibration for motor speed or turn angles at all (except a bit with the servo), at the moment it is all just tinkering around.
Anyway, I am intrigued of the Arduino project and its great to be able to create some real moving things after years of software development :)
