Evaluate state of vision, GPS, and lidar modules

[ihsan314]

We need nodes that can reliably provide us with what the rover sees as it's traversing the course.

In terms of sensors that the rover uses for vision, we have a RealSense camera, a SICK lidar, and a GPS module. It would be nice to ensure that the present nodes work, and that they present information in a format that a human pilot can easily implement.
