Practice on "follow the blue line" - 

not that exciting but it accurately following the line :-)
that is lookin 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.

Thanks RoboHappy for viewing buddy...

Well today is 8/12/2020

recovering from being a litter sick = not Covid 19  - should be back to robot adventures by next week.

Maybe the Kinect next again, Microsoft Xbox 360 with the processing program, 

I might go over the cognitive emotion, face, vision controls.

there are so many great controls that DJ created -  need to speak about them again (or out of sight, out of mind)

everyone be well -- 


get well soon.seeya next week.;)
Feel better soon EzAng.  Look forward to the next project.
