Scene and environment renders on gazebo but the robot arm doesn't

[tohsin]

I am trying to run the simple arm package from the udacity ros course. https://github.com/udacity/simple_arm_01.git simple_arm The scene shows up but the robot arm won't render in gazebo. i get this warning at the end, not sure if thats the problem but i have checked how to fix it and the solutions didnt work Controller Spawner couldn't find the expected controller_manager ROS interface I use a mac

You may miss the ros-noetic-gazebo-ros-control package?

Yeah i tried that with mamba install ros-noetic-gazebo-ros-control the arm still wont render and the warning is still there

Is that still an issue @tohsin? Which platform are you on?
