ROS-Rover has five main systems: the drive system, the autonomous system, the global positioning system, the visual feedback system, and the odometry system.

Advanced Terminal Organization

ROS robots are often controlled by many bash terminals and the startup sequence involves many roslaunch commands in different terminals. I demonstrate how you can use Tmux on your robot to codify your terminal layout into a powerful ROS administration system. The organized, repeatable tmux view can be shared in real-time by all of your teammembers for a consistent view of the robot's inner workings.

MapProxy docker container for ROS MapViz

Proxy zoomable map tiles from Google Maps to ROS MapViz for use with outdoor robots. For easy setup of MapProxy in a docker container to proxy Google Maps satellite view into a WMTS tile service so that it can be viewed by ROS's MapViz Tile Map plugin. Support for offline maps after loading once, maps stay cached. For outdoor robotics and vehicles.
