Installing rosbridge
This library makes it possible to use ros commands with javascript over a chosen port. The first two lines goes to the source in the catkin workspace and creates a package for ros:
cd ~/flexbot_ws/src catkin_create_pkg robot_gui_bridge rosbridge_server
Next we install the rosbridge package
apt-get install ros-melodic-rosbridge-server
Now we create the launch file directory and the file used for launch
mkdir ~/flexbot_ws/src/robot_gui_bridge/launch touch ~/flexbot_ws/src/robot_gui_bridge/launch/websocket.launch
Now at last we write the the necessary launch commands into the file and source it so we can use it from any directory om this terminal:
echo '<launch> <include file="$(find rosbridge_server)/launch/rosbridge_websocket.launch"/></launch>' >> ~/flexbot_ws/src/robot_gui_bridge/launch/websocket.launch source ~/flexbot_ws/devel/setup.bash
To test if it works run and look for errors:
roslaunch robot_gui_bridge websocket.launch
Setting up the connection
First check if the following command gives multiple ip's if so find a way to extract the correct one:
hostname -I
Now to setup the client, which is the computer not on the robot, write the following 3 lines in your "~/.bashrc" script:
export ROS_HOSTNAME='hostname -I' export ROS_IP="hostname -I" export ROS_MASTER_URI='http://flexbot.local:11311/'
Now to setup the server, which is the computer on the robot, write the following 2 lines in the "~/.bashrc" script:
export ROS_IP=flexbot.local export ROS_MASTER_URI='http://flexbot.local:11311/'
