How to Create a ROS2 workspace

ROS2 Tutorials Creating a workspace

example, choose the directory name ros2_ws, for “development workspace” :
```
mkdir -p ~/ros2_ws/src
cd ~/ros2_ws/src
```

Compile & Install rplidar_ros package

Clone rplidar_ros package from github

Ensure you’re still in the ros2_ws/src directory before you clone:
```
git clone -b ros2 https://github.com/Slamtec/rplidar_ros.git
```
Build rpidar_ros package

From the root of your workspace (ros2_ws), you can now build rplidar_ros 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.
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
```
Create udev rules for rplidar

rplidar_ros 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
```
