@EzAng  question why should the color matter it is using sound waves, I can see the stainless steel being a problem as it is very reflective.  I will have to investigate further, and is it worth using? the camera may be enough to detect objects in the robots path.

I only can report what I found.

for whatever reason, it crashed into certain colors, not avoided them - will test again when I get a chance.

The ultrasonic is not the best - :-)  Yes it can be used, not trusted

I will try the Sharp IR Radar  later next.

I will see what happens

I did test the Sharp IR Radar, way more sensitive.

The Ultrasonic radar scan is working better, tweaked some settings

Here is a pic of where I put the sharp IR radar and the position of the ultrasonic radar scan

All seems to be working :-)

Ezang that is lookin good.you can adjust two thing that wil make the line tracking better. first is the speed.the lower the speed the more accurate the bot will follow the line. second is the angle off the camera.amaging that you are on a bicicle lookin in front off, your front wheel.the chance you will hit somethin is very big,cause you cant see in the distants. just like your camera angle,its straight in front .by lift the camera a very little can be a huge diff. its all about how fast your ezb can calculate the full procces.

Hi Nomad, thanks for your input, I agree slower speed helps,

How are your projects coming?

I have been busy with my country / farm place, I am getting my solar energy and military generated perfected beside trying to tame the wilderness :-)

My wife and I just came back from a bike ride.

thanks EzAng
