Hi all,

I'm following this tutorial to populate a gazebo world with cob_objects.

So, first I run:

$ export ROBOT=cob4-2
$ export ROBOT_ENV=ipa-apartment
$ roslaunch cob_bringup_sim robot.launch

Then, in another terminal, I run:

$ export ROBOT=cob4-2
$ export ROBOT_ENV=ipa-apartment
$ roslaunch cob_default_env_config upload_object_locations.launch
$ rosrun cob_bringup_sim spawn_object.py table_tv

and gazebo crashes.

And I get this as error:

Error [Param.cc:452] Unable to set value [-nan -nan -nan] for key[size]
gzserver: /build/ogre-1.9-mqY1wq/ogre-1.9-1.9.0+dfsg1/OgreMain/src/OgreNode.cpp:630: virtual void Ogre::Node::setScale(const Ogre::Vector3&): Assertion `!inScale.isNaN() && "Invalid vector supplied as parameter"' failed.

Please, can someone explain me where is the problem?

Thanks.
