This page lists my open source contributions made while at Team R3 of Ryerson University in Toronto, Canada and built for the University Rover Challenge (URC) 2017. We share our rover software architecture diagram and several ROS packages for the URC competition.

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 team members for a consistent view of the robot's inner workings.

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.
