What Methods Can I Use ?

Documentation is a very good thing.  Good documentation is even better. MRL provides a large array of Services  each of which contains a large number of methods.  When you are using Python, its nice to know what methods you have to work with.  Regrettably, we have a limited number of elves working on the project and they don't always have time to provide good documentation.

Here are some suggestions the elves have suggested.

Tracking [SOLVED]

Is there any way I can start tracking objects like in Alessandruino´s video or at Instructables?

Don´t need to be facedetect, just would like to be able to track something.

I have set up 2 servos and the camera which is working fine with the tracking.min.py. Here I get a b/w picture and I can set a black dot to an object. If I move that object the black dot stays on that object but the servos don´t move. Keep getting millions of "limit out of range errors".

The NEED for SPEED !

WOOOHOOO !   IT IS WORKY !!! ... or mostly so - some fine tuning is still required...

But holy cow lets compare ....

236 micro seconds vs 18,392 micro seconds ..

Ya a bit of a difference...   

Here are some pros and cons of the new PulseIn

Sorry for the Italian!

Eyes movement is a bit sloppy even though I reprinted everything twice with a higher infill and even if I used twin servos for the right-left movement. I guess it is the best I could get with the current mechanism layout.

Alessandruino mentioned once that it would be nice to have a page which contained information regarding what we currently are working on.  This represents our group effort (TODO) similar to the Borg Inventory representing our  communal parts :)

So, here it goes :
