When running the turtlebot3_manipulation package in ROS2, an error may arise indicating that a joint is not found:

[moveit_robot_model.robot_model]: Joint 'gripper_right_joint_mimic' not found in model 'turtlebot3_manipulation' |
Specifically, the error message can prevent the proper operation of the TurtleBot3 manipulator. This issue can be resolved by editing the URDF file associated with the TurtleBot3 manipulation description.

Sometimes we need to add new objects to Gazebo to build a dynamic environment, particularly in some manipulation tasks. Suppose we test if the robot can pick up items from the floor. Thus, we may need a program to spawn models in a random position in the environment to verify our manipulation algorithms’ robustness. Like the top picture, a new cylinder is created in TIAGO’s gripper. Then TIAGO can deliver the cylinder to a free container.

This is a full demo of TIAGO placing items in Gazebo. The layout in the simulator comes from RoboCup@Home Virtual 2021

However, when I tried to run Gazebo 7 under Ubuntu 20, there is no title bar on the top and I cannot resize this window.

I made SDF models for most YCB objects that can be used directly in Gazebo, and provided them with the following optimizations:
