No contact information returned
As can be seen from the picture below there is obviously a collision. However no contact information is returned.
At the beginning of collision a lot of data returned, but after the system gets to equilibrium contact information is not longer available.
Is it a bug or I have to tune some simulation parameters? Is there any workaround for this?
Thanks,
Boris
EDIT: Here are model and world SDFs.
I just noticed that there is a solver of type quick in my world. Can it be the cause?
EDIT #2: Tried Solver type world, but now I am unable to spawn any objects from gui - Gazebo simply dies.
Hi, are you getting the contacts from messages, or you have your own plugin? If it is a sensor, then seeing the sdf file might also help.
I have my own plugin, but `$ gztopic echo /gazebo/default/physics/contacts` also shows nothing (except for time).
In your plugin is the sensor active? ( 'this->parentSensor->SetActive(true);' ) But I suppose yes, if you said you get the data at the beginning.
Yeah, sure, it is active.
Inactive objects get automatically disabled. This will stop collisions from being reported.
@nkoenig, so what triggers them back to active? Thanks.
there is a <allow_ auto="" _disable=""> tag in within <model> that you can set to false. You can give this a try
An active object that collides with an inactive object will make the inactive object active.
