Thank you cyrano.

This video is an example of what is streaming from the pi. The video starts with the robot starts about three meters from the target. This video has me thinking that the math for calculating the servo angles used to point the camera is working correctly, even if the laser pointer could be mounted better.

Now I just need to write some routines that go from a screen coord to a vector in world space. Then I can just project that vector to the floor plane and then hopefully I can use the blob tracking to chase tennis balls that I roll by the robot.

Now, that's an offer too good to refuse :-). Great work on the robot. I'm especially interested in how you have managed to implement the image processing into the GPU.

If you could share the code, that would be much appreciated. Of course, happy to contribute back any work we do with it as well.

Cheers.

But little information, links, app (android), Open-Cv code?

https://github.com/drhastings/balance, this is pretty up to date and has the blob tracking functionality. Good luck! Things started to sprawl as I neared the end. If you can find a comment, chances are it is incorrect.
