As glorious @chapulina said, referencing the object's callback solves the issue.

No, that might be a solution because i'm referencing the actual receiver of the callback. Will try and get back to you w

2017-03-19 04:04:41 -0600 asked a question Weird compile error using ROS and Gazebo libraries

Hi guys,

Came across the weirdest compile error:

In function ignition::math::Vector3<double>::operator[](unsigned long) const': gzwidget.cpp:(.text._ZNK8ignition4math7Vector3IdEixEm[_ZNK8ignition4math7Vector3IdEixEm]+0x2b): undefined reference toignition::math::IndexException::IndexException()'

libgazebo_common.so is throwing this. What the hell is going on ? Im linking ignition_math2 libraries, people in ignition sent me here.

Thanks

Hey guys !

Does anyone have a working very basic gazebo rendering example in Qt5 ? i'm really struggling and having really odd behaviours including gazebo/gui stuff. Help here would be greatly appreciated !

Thanks

2016-09-25 12:03:34 -0600 asked a question Not able to delete model

Hey ! I have this simulator that i'm building, using a custom client and gazebo's server. I'm using a gazebo topic (using GzString) to pass generic data to my world plugin. Adding models work just fine (despite some bugs related to Ign-Rendering and not loading correctly some visual properties), but when removing models, it just hangs in there forever.

models_ = world_->GetModels();   // get models
// name is the name of the model to be deleted
for(unsigned int i = 0; i<models_.size(); i++){
    if(name.compare(models_[i]->GetName())==0){
        ROS_INFO("Found model to be deleted.");
        world_->RemoveModel(models_[i]); 
        model_deleted = true;   
    }
}

Any hints on how to solve this ?

2016-09-21 09:27:09 -0600 commented answer Crazy behaviour from a simple "board-like" model

Thank you all for your answers ! I've already corrected my center of mass of the models and the building is going fine, no odd stupid behaviours now. Although, i still didnt manage to work on my values for the moments of inertia which are crucial to obtain a truthful simulation

2016-09-21 04:56:36 -0600 commented answer Crazy behaviour from a simple "board-like" model

Yes you are right @chapulinha ! How do i change the center of mass ??? Also, any way to correctly compute the inertia of something ?

2016-09-21 04:52:42 -0600 commented question Lift Controller Plugin

May be, we (you and i) should use boost::mutex * GetSetWorldPoseMutex () const before making any changes to a model ... In my plugin i also dynamically change the sdf of the robot and odd behaviours occur.

2016-09-20 19:27:24 -0600 asked a question Crazy behaviour from a simple "board-like" model

Im building a more complex model but i created a simple one to start. It has a very weird behaviour that i documented by video so you can all give your opinions !! VIDEO ---------> VIDEO

In the video it is visible the SDF for the model. I made my world setup using this:

<physics type='ode'>
  <max_step_size>0.015</max_step_size>
  <real_time_update_rate>67</real_time_update_rate>
  <gravity>0 0 -9.8</gravity>
</physics>

But works the same way with or without it. May be its STL related ? Can figure it out.

2016-09-20 19:14:55 -0600 commented question Lift Controller Plugin

That happens to me also, when using factory message to spawn a model, one part of the model goes to the correct place, the other goes to a completly different position ... Gazebo is very buggy sometimes, it doesnt handle model spawn/delete on the fly very well, at least for me tho
