2014-03-18 12:27:46 -0500 answered a question error: ‘ConnectWorldUpdateStart’ is not a member of ‘gazebo::event::Events’

ConnectWorldUpdateBegin is correct not ConnectWorldUpdateStart

I don't know why your tutorials are wrong?!!!

hi, I try to write a plug-in. but there is a problem when I run "make" command:

this->updateConnection = event::Events::ConnectWorldUpdateStart(
    boost::bind(&MobileBasePlugin::OnUpdate, this));

And this is the error:

In member function ‘virtual void gazebo::MobileBasePlugin::Load(gazebo::physics::ModelPtr, sdf::ElementPtr)’:

error: ‘ConnectWorldUpdateStart’ is not a member of ‘gazebo::event::Events’

I solve my problem by adding "setenv GAZEBO_PLUGIN_PATH ~/my_plugin/build" to .cshrc

I did not install gazebo in the computer by myself. I am a PhD student and the university tech group installed it for me. I have not a root access and I don't know what is bachrc? I did your command : echo $GAZEBOPLUGINPATH and the same error: GAZEBOPLUGINPATH: Undefined variable.

2014-03-12 15:01:44 -0500 asked a question Error in Setup gazebo plugin paths - GAZEBO_PLUGIN_PATH

Hi, I am trying to add a controller to my robot, (using plugin). So I am going to follow the tutorials Mobile Base Control and Plugin Hello World. But I have three problem: 1 - /grad/hadi.kazemi/myplugin/myplugin.cc:2:21: fatal error: gazebo.hh: No such file or directory so I add a /gazebo/ to all include lines and the error vanished.

2 - error: ‘ConnectWorldUpdateStart’ is not a member of ‘gazebo::event::Events’ when I try to make, so I delete this line (this line was in the first tutorial).

3 - after removing the make worked well but when I try to run this command: export GAZEBOPLUGINPATH=pwd:$GAZEBOPLUGINPATH or export GAZEBOPLUGINPATH=${GAZEBOPLUGINPATH}:~/myplugin/build/ it gave me this error: GAZEBOPLUGINPATH: Undefined variable. and so when I add my model to the world (using insert) I have: Error [Plugin.hh:152] Failed to load plugin libmyplugin.so: libmy_plugin.so: cannot open shared object file: No such file or directory

how can I handle these errors?

2014-03-08 13:47:16 -0500 asked a question How change the SDF defined model runtime? (to lock a revolute joint)

Hi, I want to add a Lock property to a revolute joint, I mean I want to Lock the joint so that there is no DOF for that joint anymore and then release the lock again. How can I handle it? I think maybe I should 1 - add a fixed joint exactly in the revolute joint position so it will prevent the revolute joint revolution. 2 - or change the <xyz> to 0 0 0 To do that I should change the model (SDF) runtime. how can I do that in gazebo? Thanks,

2014-03-05 10:15:30 -0500 asked a question How create spherical robot model (hollow sphere)?

Hi, Is there hollow sphere in Gazebo? I want to model a spherical robot but I can't find a hollow sphere on Gazebo? How can I model that robot? I left Webots simulator because it did not support hollow sphere. Thanks
