How to Create a ROS2 workspace

ROS2 Tutorials Creating a workspace

1. example, choose the directory name ros2_ws, for "development workspace" :

   mkdir -p ~/ros2_ws/src
   cd ~/ros2_ws/src

Compile & Install sllidar_ros2 package

1. Clone sllidar_ros2 package from github

   Ensure you're still in the ros2_ws/src directory before you clone:

   git clone https://github.com/Slamtec/sllidar_ros2.git

2. Build sllidar_ros2 package

   From the root of your workspace (ros2_ws), you can now build sllidar_ros2 package using the command:

   cd ~/ros2_ws/
   source /opt/ros/<rosdistro>/setup.bash
   colcon build --symlink-install

   if you find output like "colcon:command not found",you need separate install colcon build tools.

3. Package environment setup

   source ./install/setup.bash

   Note: Add permanent workspace environment variables. It's convenientif the ROS2 environment variables are automatically added to your bash session every time a new shell is launched:

   $echo "source <your_own_ros2_ws>/install/setup.bash" >> ~/.bashrc
   $source ~/.bashrc

4. Create udev rules for rplidar

   sllidar_ros2 running requires the read and write permissions of the serial device. You can manually modify it with the following command:

   sudo chmod 777 /dev/ttyUSB0

   But a better way is to create a udev rule:

   cd src/rpldiar_ros/
   source scripts/create_udev_rules.sh

Notice: different lidar use different serial_baudrate.
