2012-05-07 08:32:42 -0500	answered a question	Failed to apply efforts to joints in gazebo on ros fuerte The basic problem is that there was a bug in my electric-fuerte migration, fixed in the following patch, to be released with 1.6.8. https://code.ros.org/trac/ros-pkg/changeset/39394
2012-05-07 08:32:30 -0500	asked a question	Failed to apply efforts to joints in gazebo on ros fuerte Hi all, I follow this tutorial using Fuerte, but the link does not rotate after $rosservice call gazebo/apply_joint_effort '{joint_name: link_joint, effort: 0.01, start_time: 10000000000, duration: 1000000000}' instead I get ERROR: transport error completing service call: unable to receive data from sender, check sender's logs for details I have launched $ roslaunch gazebo_worlds empty_world.launch on ROS Fuerte, Ubuntu 11.10 64-bit. Where could I see sender's logs as suggested by the error msgs above? Is there another way (how) to apply effort to joints in gazebo in Fuerte? I note that the tutorial I follow was written for C-Turtle.
