------- Setup the ROS_MASTER_URI ----------- If ROS Master runs on the Raspberry Pi, you need to set export ROS_MASTER_URI=http://ubiquityrobot.local:11311

In case you are running ROS Master on your local host, set export ROS_MASTER_URI=http://localhost:11311

To speedup the process you can edit ~.bashrc with:

source ~/catkin_ws/devel/setup.bash export ROS_IP=ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'

export ROS_MASTER_URI=http://ubiquityrobot.local:11311 or export ROS_MASTER_URI=http://localhost:11311
