One day while I was at my parents place cleaning up, I found an old robot platform that I didn't get to use yet.

Integrating the SLAM data from the T265 and the depth information from the D435i, with the ROS stack might be a challenging enough task on its own. A simple mobile robot platform with differential kinematic would be the perfect starting point for exploring this without the other challenges of the entire system

So here's ROSie.
