I havn't done very much by way of a write up on the GROK2 robot so far, so here is some explanation of the story to date.

The robot is still quite static, although it can be driven by joystick. The next stage is to create a URDF model and try out some of the ROS mapping/localisation to see whether it's suitable for use with stereo vision. From the navigation stack's point of view it shouldn't care what sensors are being used, since all it will be seeing is point cloud data.
