Respected Sir,

1. What does it mean to source ALL the webshells in the following pic

Hello @abdulbasitisdost,

1. When you compile your package in order to create a new message, you need to source the Web Shell in order to be able to use this new message. To source the Web Shell means to execute the following command:

source ~/catkin_ws/devel/setup.bash

2. Yes, the node name can be anything you want.

Best,
