2016-11-05 07:43:45 -0500 | commented question | Problem loading Stl in rviz Hi, I meet similar problem like you. I draw a model file using sketchup, and convert it to stl using mashlab. This model file can be displayed in gazebo but get this "UnboundLocalError: local variable 'slider' referenced before assignment" error when loading in rviz. |
2016-09-19 08:50:32 -0500 | asked a question | Problems with the old moveit! tutorials about benchmark tools Hi there, I'm new to moveit!, and currently trying to use the benchmark tool to do reachability analysis. I find some old tutorials at http://moveit.ros.org/doxygen/moveit_... and http://moveit.ros.org/wiki/Benchmarking But what I get is 404 not found. Does these tutorials still exist? Or would anyone provide me with some documents about how to use the benchmark tools? Thanks in advance. |

Here is my model: When I use the model in the comment every thing is fine, but when I use the model now, it appears that the second link would go below the first link. Why does this happens? |

2016-06-25 10:18:49 -0500 | answered a question | no factory exists problem with Gazebo ros control tutorial I solved this problem just several minutes ago. It turns out the error appears because the .so file is collapsed. So I download the source code from git and re-generate the .so file use catkin_make. The last step would be copy the .so file to /ros/<dist>/lib folder, and problem solved. And then PROMBLEM SOLVED! |
2016-06-25 08:45:29 -0500 | asked a question | no factory exists problem with Gazebo ros control tutorial Hi there, My ros distribution is indigo and my ubuntu distribution is 14.04. I'm currently learning ros control. And it speed learning curve really makes me frustrated. Here is my question, I tried the Gazebo ros control tutorial at http://gazebosim.org/tutorials/?tut=r... . When typing "roslaunch rrbot_control rrbot_control.launch" it worked at the first time. But things get weird when I come back several days later( Accurately yesterday..... ). I got errors when loading the control_plugin. But when I call the service as the third error suggested I find the effort_controllers/JointPositionController exist. And when I type "rospack find effort_controllers" I can find the package under ros/indigo/share/ Furthermore at file effort_controller_plugins.xml it actually contain: <class> name="effort_controllers/JointPositionController" type="effort_controllers::JointPositionController" base_class_type="controller_interface::ControllerBase"> <description> The JointPositionController tracks position commands. It expects a EffortJointInterface type of hardware interface. </description> </class> I try to remove and re-install the effort_controllers use "apt-get" several times but the errors still exist. Please help me out of this. Thanks in advance. Erli |

2015-11-12 08:00:51 -0500 | commented question | Problem with converting rosmake package to catkin package :(. I remove the build/ and devel/ but unfortunate nothing changed, I still got the same error message. I check the devel/ folder there are no header file from mathlib generated there, I think this is the reason why seds can't find the .h file. Anyway thank you for your help:) |

Both package contains several .cpp files and .h files but there are no main function in any those cpp files, and none of this file have ros functions like ros::initial() blah blah, so they are just ordinary cpp files.
