# How to attach two links in Gazebo with using roslaunch

I have already read this answer How can two links of different robots attach to each other on contact during simulation?. However, I don't understand clearly.

I am a beginner in ROS and Gazebo and I have finished tutorial Gazebo. Also, I am trying to realize the environment of harvesting something with using MoveIt! and Gazebo. I finished to realize both of robots and tree which has something like fruits.
