Package: sdrc_urc_arm

Software to control the rover's arm.

Package: sdrc_urc_biology

Software to control the rover's biology subsystems. Note: currently empty, needs updating.

Package: sdrc_urc_bringup

Software that launches the main subsystems. When in doubt, use these launch files! Note: currently empty, needs updating.

Package: sdrc_urc_chassis

Software that interfaces with our chassis motor controllers. Note: currently empty, needs updating.

Package: sdrc_urc_comms

Software that interfaces with our access points (routers) to allow us to detect if the rover loses communications. This package also provides programs to drive the access point motors to maintain line-of-sight with the base station. Note: currently empty, needs updating.

Package: sdrc_urc_cv

Computer vision software, primarily used to detect the AR tags used in the University Rover Challenge. Note: currently empty, needs updating.

Package: sdrc_urc_description

The URDF definitions of the rover and ROS Gazebo launch files to spawn the rover model in an empty world. Note: currently empty, needs updating.

Package: sdrc_urc_gazebo

Software that launches the Gazebo Simulator with a variety of options of models and terrains to simulate. Note: currently empty, needs updating.

Package: sdrc_urc_gps

Software that interfaces with our GPS unit. Note: currently empty, needs updating.

Package: sdrc_urc_gui

Software that defines and launches our graphical user interface (GUI). Note: currently empty, needs updating.

Package: sdrc_urc_jetson_nano

Software that interfaces with the rover's Nvidia Jetson Nano microcontroller. Note: currently empty, needs updating.

Package: sdrc_urc_joystick

Software that interfaces with a variety of joysticks and writes the values of each joystick to ROS topics. Note: currently empty, needs updating.

Package: sdrc_urc_lidar

Software that interfaces with our LiDAR unit. Note: currently empty, needs updating.

Package: sdrc_urc_mapping

Software used to provide simultaneous localization and mapping (SLAM) on the rover. Note: currently empty, needs updating.

Package: sdrc_urc_navigation

Software used to autonomously navigate using the ROS Navigation Stack (NavStack). Note: currently empty, needs updating.

Package: sdrc_urc_pi

Software that interfaces with the rover's Raspberry Pi microcontroller. Note: currently empty, needs updating.

Package: sdrc_urc_restricted

Package only accessible by members of the Sun Devil Robotics Club GitHub Organization. Contains models, code, and other sensitive information that give us a competitive advantage!

Package: sdrc_urc_zed2

Software that interfaces with the rover's ZED2 camera. Note: currently empty, needs updating.

In addition, this folder also contains the following:

• install.sh (A script that installs all dependencies needed for the sdrc_urc ROS package.)
• uninstall.sh (A script that uninstalls all dependencies needed for the sdrc_urc ROS package.)
• extras/etc/udev/... (Linux udev rules for remapping joysick controllers to new names.)
