  Getting Started

  Note It is highly recommended to develop in a virtual machine because our install procedures are not isolated and can be invasive (VM Instructions)

  1. Install VMWare Workstation Player
  2. Download, Unzip, and Run in VMWare our preconfigured VM
  3. Open the ~/colcon_ws folder in VSCode
  4. If working on Arduino, install the PlatformIO VSCode extension

Commands to know

1. Install dependencies with rosdep
   • cd ~/colcon_ws
   • rosdep install --from-paths src --ignore-src --skip-keys=librealsense2 -r --rosdistro $ROS_DISTRO -y --include-eol-distros
2. Build the desired package
   • colcon build --packages-select <Package folder name>
   • build <Package folder name>
     • Use build function defined in ~./bashrc
3. Source the setup script so ros2 can find the packages in this workspace
   • source ~/colcon_ws/install/setup.bash
