@luminize , Is there a good video explaining the control on your robot? I saw the Europe Meeting Video 1, and it said part 2 was your presentation, but I can't find it :-/

@evanmj i think that video part still needs to be finished. I dont have a write up. Plus there's still work to do to clean up my dev branch. (Procrastination) But I can gather my stuff and do a write up on my blog.
In short: ROS sends messages, so a listener node listens to these specific messages. That listener is written in Python and that makes it easy to use the Cython bindings. The listener puts segments into a ringbuffer (HAL). Then an interpolator component interpolates the positions so we get a correct position every ms. The reason for that is that ROS has no isochronous segments.

Thanks. I've been following the ros integration. Are you using closed loop steppers? Or are those smalls servos?

ROS is massive, but lacking just a few things. I came to MK from ROS, but I've yet to apply either to anything useful. They both have a large learning curve.

I need to find out how the licensing works for commercial applications for both though, if it is even possible
