Hi i've added my ultrasonic, different encoders version bot to the code. I rearange the code base and cleand it up (pep8).
I hope i find next week the time to add it to the o-botics site and some pictures ;)

This looks great! I merged your pull request. I was just sitting down to write something similar to incorporate the QuickBot v2 code. But I like how you have structured it.

I am going to make a new branch for the QuickBot v1 and not update that anymore. Then merge in the new code for QuickBot v2 into the master branch. That way people from the course with original QuickBot can still get to the original code. Do you think that is the best approach? Or I can just add a new class file in the "xbots" folder called "quickbot_v2.py"

I guess the repo name needs to be updated. Maybe xbot_bbb instead of quickbot_bbb.

Oh nice that was fast.

Yeah i would add the v2 version simply as an new py file as you proposed. In the run.py you can add than this:

RTYPES = ('quick', 'quickv2', 'ultra')
...
    if options.rtype == 'quickv2':
        import xbots.quickbot_v2
        qb = xbots.quickbot_v2.QuickBot(options.ip, options.rip)
        qb.run()
...

If we get more bot's in the future we can reconsider a renaming!?
