Sure, the pose in the world frame is estimated at 30 Hz. Over longish distances there's some drift so a global optimization step is needed.

I'd like to release a developer API (Forge currently runs on Android, Windows & Linux) hopefully later this year, which should be what you're looking for.

Also, I worked in mobile robotics at Willow Garage a few years ago (https://www.youtube.com/watch?v=0aqghgoeCWk), so I'm keen to see Forge used in robotics.
