On Ubuntu 14.04 and Indigo use Eigen3 instead of Eigen

Calling service rosservice call /gazebo/setphysicsproperties and setting maxcontacts to 100 does not work. After calling service rosservice call /gazebo/getphysicsproperties the maxcontacts is still 20.

while launching current shadow robot hand in Gazebo, there is an error: pure virtual method called terminate called without an active exception

Gazebo simulator freezes. If I launch other robots, there is not error with gazebo_ros_controller_manager.

Is it because of the empty namespace?

@GuiHome the objects in Gazebo freeze after calling this service. However in RVIZ, I see that frames move and there even collisions. It seems that simulation is working but the visualization in Gazebo fails. The maximum number of contacts is still 20.

Where and how can we set maximum number of contacts in Gazebo?

By default the max. num. of contacts is 20 "rosparam get /gazebo/max_contacts" Setting the parameter to any other ( ex. 100) " rosparam set /gazebo/max_contacts 100 " does not affect the simulation results, I am always getting 20 contacts using gazebo plugin bumpers.

Thank you! One comment is that the /tf should be publishing data at sufficient rate. Use rostopic hz /tf to see the rate. Gazebo publishes link states at 1kHz by default. But using tf methods simplifies transformations.

How to get position of a contact with respect to to frame of the link that is in contact?

I am using Gazebo 1.9 and ROS Indigo. I am getting contact positions wrt world frame.

Hi! I am using ros hydro.

gzserver is in local folder: /home/zhan/local/bin/gzclient not in: /usr/bin/gzserver

When I run gazebo_ros I get an error "gzserver: symbol lookup error".

Hello!

I am getting the same error as in answers.ros.org/question/175148/how-to-i-fix-libgazebo_ros_paths_pluginso-undefined-symbol-error/). I use Ubuntu 12.04, ROS Hydro, Gazebo. When I run Gazebo (rosrun gazebo_ros gazebo) without sourcing catkin workspace ( source ~/catkin_ws/devel/setup.bash) Gazebo works. When I source catkin_ws, I get the error: "gzserver: symbol lookup error: /home/USER_NAME/catkin_ws/devel/lib/libgazebo_ros_paths_plugin.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2_RSt6vectorISsSaISsEE" and in followin glines "[gazebo-2] process has died [pid 12411, exit code 127".
