After I run the launch file quiz_control.launch in my quiz_control package, I can see the controllers by typing rostopic list and I am able to move the robot by publishing commands with rostopic pub. So why am I i losing points on the quiz for that? For example, after raising the shoulder with shoulder_lift, I can run
rostopic pub -1 /ur5/elbow_joint_position_controller/command std_msgs/Float64 “data: -0.3”
to make the elbow move and follow that with commands to make the wrists move.
When I made my custom controller and use it for the shoulder lift joint, it doesn’t load, just as described at the end of 4 - Create a Controller. Can you help with that? From the way the quiz is graded, it doesn’t look like I’m losing points for that. But it’s hard to tell how the quiz is testing the project_controller package.
