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.

Fail to load library when trying to write a custom hardware interface for Arduino to control servo motors
Hello, I am learning ROS2_control by trying to wrtie a custom hardware interface to control 2 servo motors via Arduino. I am referencing these two repository ros2_control_demo_hardware and diffdrive_arduino when trying to write my code. I can successfully move my pan-tilt robot in simulation (Gazebo) and fake hardware mode. However, I failed to move it in the real hardware after a week of trying. below is the error i got when i ran the launch file. Can anyone tell me where i did wrong and how should i modify my code to correct it? Many thanks. Here is my code here

Will the joint limits in my URDF file limit the real components or just the simulation? (ROS2: Foxy)
There is no guarantee that limits in your URDF will affect the actual robot hardware. You need to make sure the hardware driver is applying those limits by either parsing the URDF or using parameters specified via the ros2_control xacro file, which is typically included in the robot's description (e.g., https://github.com/ros-controls/ros2_control_demos/blob/master/ros2_control_demo_description/rrbot_description/ros2_control/rrbot_system_position_only.ros2_control.xacro).

ROS2_Controllers Hardware Interface to uROS communication via topics?
I've been messing with the ROS2 Control Demos, trying to adapt it to a physical differential drive robot I've been working on. I've had limited success communicating hardware commands from a Raspberry Pi 4 running the ROS2 differential drive controller to a microcontroller (currently a Teensy 4.1) that is in charge of interfacing with the robot hardware. Techniques I've gotten "working" for communication between the Pi and are serial (via USB) and ethernet (UDP).

Robot Operating System: Expose Control Nodes for an Interactive Simulation in Gazebo
Exposing controller nodes explicitly involves a number of steps. Loosely following the official documentation, ros control demo repository and my own experience, these are:

Robot Operating System: Getting Started with Simulation in ROS2
The launch file can also transform the Xacro files during startup, as shown in the diff_bot example. For example, to load the Gazebo configuration, you need to execute this:

Hello everyone I need help building a tutorial for Ignition Gazebo as I keep getting errors when building.
Hello everyone, I am currently doing my master thesis and I am trying to use ROS2 in combination with Gazebo (or Ignition Gazebo) and MoveIt2 to simulate a robot. I want to use this Tutorial and go from there. But I keep getting errors when trying to build ign_ros2_control from source. I have done everything as described in the tutorial. Below are informations on what I am using: Kubuntu 20.04 Focal Fossa ROS2 Galactic (package) Ignition Gazebo Edifice (package) MoveIt2 (package) ros_ign (package) ign_ros2_control (from source) (all of the above is also linked in the linked tutorial)
