ROS packages for AR3
Hello, do you know how to using Python code to control the arm rather than using GUI in rviz?
"ros2 launch ar3_moveit_config sim_demo.launch.py" command doesnt work saying :
file 'sim_demo.launch.py' was not found in the share directory of package 'ar3_moveit_config' which is at "'/home/yagi/dev_ws/install/ar3_moveit_config/share/ar3_moveit_config'"
found a demo.launch.py instead but that gives errors too :
"Task exception was never retrieved
future: <Task finished name='Task-2' coro=<LaunchService._process_one_event() done, defined at "
"ament_index_python.packages.PackageNotFoundError: "package 'controller_manager'"
`--- stderr: ar3_bringup
CMake Error at CMakeLists.txt:26 (find_package):
By not providing "Findament_cmake_mypy.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"ament_cmake_mypy", but CMake did not find one.
Could not find a package configuration file provided by "ament_cmake_mypy"
with any of the following names:
ament_cmake_mypyConfig.cmake
ament_cmake_mypy-config.cmake
Add the installation prefix of "ament_cmake_mypy" to CMAKE_PREFIX_PATH or
set "ament_cmake_mypy_DIR" to a directory containing one of the above
files. If "ament_cmake_mypy" provides a separate development package or
SDK, be sure it has been installed.`
Hello, I did all the steps before ros2 launch ar3_bringup rviz.launch.py
and then got an error:
[INFO] [launch]: All log files can be found below /home/flake/.ros/log/2023-04-05-19-54-26-896724-raspberry-6237
[INFO] [launch]: Default logging verbosity is set to INFO

in file: /home/flake/ros2/ar3_ws/install/ar3_description/share/ar3_description/urdf/ar3.urdf.xacro
I'm using Raspberry Pi 4B 4GB with Ubuntu 22.04 Jammy and ROS Humble.
Also tried using a use_fake_hardware
parameter, but faced this error again.
Thanks for help!
does this package supports AR4 or do i need to make changes @SyllogismRXS @emanuelbuholzer
