Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ROS using Docker
I recently pushed changes to this open source repo, enabling a docker + docker-compose workflow: https://github.com/elephantrobotics/mycobot_ros

Elephant robotics-the collaborative robot with computer vision - myCobot with Jetson Nano educational solution
• Add the relative coordinates(x1, Y1) from the centre of the gripping area to the manipulator (X2, Y2) to obtain the relative coordinates (X3, Y3) of the object block to the manipulator. The specific code implementation can view the program source code.(Check on Github)

turtlebot3_teleop for iron
You could try downloading the package: https://github.com/ROBOTIS-GIT/turtlebot3/tree/humble-devel and just build / run in your iron workspace.

Trying to evaluate if passing object handles to various constructors is a good design choice
To give more context, I am using ROS2 (robot operating system) to build a small mobile robot for hobby/learning. To learn by ready other code, I am looking at a very popular ROS project called Turtlebot3.

Okay guys, thanks very much, I understood the actions! Now I’m confused about xml and urdf stuff. The idea is to make a 2-wheel robot moving in gazebo, but how to make it? I really demotivates bcs ros topics doesn’t give any good explanation…
You can copy and modify the (turtlebot3)[https://github.com/ROBOTIS-GIT/turtlebot3] repo as basis. They have different robot models for gazibo simulation and starting point for ros navigation.

Big question
- if you want to later make a more complicated robot (that uses cameras, has robotic arm etc.) you'd want to look into ROS (robot operating system). If you are in/going to university I highly recommend you join an engineering design team. For an example project you can refer to https://github.com/ROBOTIS-GIT/turtlebot3

Turtlebot3 Refuses to Move in a Straight Line
The tutorial I was using (which comes straight from nav2) says to run ros2 launch nav2_bringup navigation_launch.py . However, when I went to tune Turtlebot3 via the .param file, it did no change whatsoever. This is because, by default, the file uses up this param file that is significantly different than burger.yaml; After changing it the costmap looks completely different. After reading the source code for the .launch file of the Turtlebot3 nav package for galactic and nav2, I've found out that running ros2 launch nav2_bringup navigation_launch.py params_file:=[PATH_TO_BURGER_YAML] works and completely fixes this issue.

Using another Local Planner
If you're looking for an example of setting the local planner then the turtlebot3 (which I've seen you're using in your delivery_robot_sample package) has an example here: https://github.com/ROBOTIS-GIT/turtlebot3/blob/master/turtlebot3_navigation/launch/move_base.launch
