rif-robotics / ar3_ros Goto Github PK

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

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!

getting this error when i try to launch it

"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'"

Hello, do you know how to using Python code to control the arm rather than using GUI in rviz?

does this package supports AR4 or do i need to make changes @SyllogismRXS @emanuelbuholzer

• ROS2 Foxy is properly installed and tested to work
• The files downloaded from github haven't been altered.
• ament_cmake_mypy and the other files seem to be installed in the right (default) places.
• I've gone through the .bash and .sh files to see where my paths might be misdirecting the CMAKE_MODULE_PATH.
  Error printout to the terminal:
