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:

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:

Some information on Vyommitra (from ASET-2022)
Check out the paper titled "Simulation Studies on Vision based Humanoid Arm Operations" , they have used Gazebo environment ( https://gazebosim.org/ ). However making it online, I don't think so they will.

Gazebo Ignition Apple Silicon Support!
Hi guys, Have been anyone able to run gazebo on linux/macos arm64 machine? is there any upcomming support for m1 apple chip if not? what is your solution to run a simulation on m1 do you have any advices? I have tried to build gazebo on my own but it seems it won't build whatever I try.

Can you recommend a robotics kit for someone who wants to break into a role as a software robotics engineer? Explained more below.
If you dont wanna spend any extra cash, there is the gazebo simulator (http://gazebosim.org/), which supports ROS (https://www.ros.org/).

C++ and Robotics.
Simulation is a strong choice too. ARGoS, Actin, Webots, Gazebo and V-Rep are some examples. A simulation will give you the opportunity to use some robots in different environments (with a lot of configurations). Gazebo has a big community and documentation, V-Rep is the more powerful one (and my pick).

I want to get into robotics and have $1000 to spend! Where to start?
I've used Gazebo; it's very well-integrated into the ROS universe. Lots of open-source sample 'worlds' and robot models out there: http://gazebosim.org/. There is also https://cyberbotics.com/, which looks neat, but I haven't tried it.
