Summary of Changes

Hello @GyuH13, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on bumping the version of the TurtleBot3 Manipulation packages to 2.2.1. The most significant functional change is the complete removal of the Gazebo simulation environment and its associated components and dependencies. Additionally, there are numerous minor code style and formatting improvements across various launch and source files.

Highlights

• Version Bump: The version number has been updated to 2.2.1 across all turtlebot3_manipulation related packages.
• Gazebo Simulation Removal: The Gazebo simulation environment for the TurtleBot3 Manipulation has been removed, including related files, dependencies (gazebo_ros, gripper_controllers, warehouse_ros_mongo), and installation targets.
• Code Formatting and Imports: Various Python launch files and C++ source/header files received minor formatting updates (e.g., double quotes to single quotes) and import reordering.
• MoveIt Configuration Updates: The MoveIt RViz configuration file (moveit.rviz) has the warehouse host and port commented out. Minor formatting adjustments were made in several MoveIt launch files.

Code Review

This pull request primarily bumps the package versions to 2.2.1. Key changes include the removal of TurtleBot3 Manipulation Gazebo simulation support, evidenced by updates in changelogs, CMakeLists (removal of worlds directory), and package.xml files (removal of gazebo_ros dependency).

Additionally, the MoveIt warehouse integration via warehouse_ros_mongo seems to have been disabled, as seen by changes in RViz configuration and package dependencies.

Numerous Python and C++ files have undergone stylistic changes, such as consistent use of single quotes in Python, import reordering, and code formatting. These changes generally align with common best practices (e.g., PEP 8 for Python, common C++ formatting conventions) and improve code consistency and readability.

One point for consideration is the removal of an explicit dependency on gripper_controllers in turtlebot3_manipulation_bringup/package.xml, which is detailed in a specific comment.
