Revision history [back]

Hi,

I just went through and updated the entire gazebo_ros_control tutorials with my lastest work, I added more details and clarified some of the concepts. I tested all the RRBot code and I encourage you to review the changes in the tutorial or on the github demo. This has been one of my main projects this summer while an intern at OSRF.

Concerning your question, I don't think its a big deal that is says "unknown type" - it always does this for me. I don't know why it does that but I think its an issue with lower level ROS stuff and not with the Gazebo code. Is it causing you issues? With everything running correctly for RRBot I get this output from rosnode info gazebo - which seems to be the same as your output.

The command from the tutorial for publishing to joint controller should work:

rostopic pub -1 /rrbot/joint1_position_controller/command std_msgs/Float64 "data: 1.5"
