Two Wheeled Arduino Robot Part 1

16 Nov 2014

The out line of this project is a two wheeled Arduino robot using the Arduino Mega.

So far i have built the head which consist of two HC-sr04 distance sensors mounted on a cardboard frame rotated by a servo.

I am planing to use the http://www.pololu.com/category/60/micro-metal-gearmotors for drive motors.

The code i used to test the head compares the two HC-sr04 distance sensors and turns the servo motor in the direction of the distance sensor with the least distance.so it can track objects.

Here is a video of the head:

Any suggestions are welcome.

Hi Tim I like that way you make good use of materials at hand to build your prototypes. It is very impressive. You will have to use some fuzzy logic for situations where the robot is walking between equally distant objects.

It can track objects farther away. but it needs a biger object to track.
I have tested the sensers and they are acurit out to 11 feet .

Hi Tim,

It looks like you are off to a good start.
What is the detection range for your sensors? It looked like you had to get really close to have it respond. Is that going to be ok for your robot operation?
