There are two solutions: Add the static tag to your model <static>1</static> Add a valid inertial block

2017-05-28 23:51:37 -0600 marked best answer Gazebo 7.0.0 crash on heightmap insertion

In Gazebo 7.0.0 if I try to insert an model with a heightmap Gazebo either hangs or closes with a crash. In the following example, I attempt to insert the Appolo15 landing model

Either I'll get

Or I might get this this message too

Any ideas? Wondering if the easy fix is to uninstall the Gazebo version that ships with ROS and install the latest one.

An easy but probably not optimal solution is to install Gazebo 8. It's not the version that ships with ROS Kinetic, but

2016-01-04 17:06:54 -0600 commented question Can't load libRayPlugin.so

Nevermind, it seems I forgot I had to start Gazebo with the ros wrappers to get the ros plugins working.

2016-01-02 23:26:32 -0600 asked a question Can't load libRayPlugin.so

I'm working with ROS Indigo and Gazebo 6.5.1 and I have installed the corresponding ROS packages by running

sudo apt-get install ros-indigo-gazebo6-*

I've included the libgazebo_ros_laser.so plugin in my .sdf file but when I launch the world and insert the model I get

[Err] [Plugin.hh:165] Failed to load plugin libgazebo_ros_laser.so: libRayPlugin.so: cannot open shared object file: No such file or directory

I know all of this is installed and I found the actual .so files in my computer. I've tried to force add the path to my GAZEBO_PLUGIN_PATH environment variable by doing

export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:/usr/lib/x86_64-linux-gnu/gazebo-6.5/plugins:/opt/ros/indigo/lib

But still no luck. Any ideas?
