2013-07-06 10:23:27 -0600 answered a question atlas does not react in gazebo

Try using AtlasCommand message instead. I had the same problem when the controller was updated. Plus you should check this tutorial http://gazebosim.org/wiki/Tutorials/drcsim/2.6/atlassiminterface because the Atlas needs to be in user mode to be controlled.

Hope it helps,

I found out... Never mind.

I was using the same pointer name for two different joints without realizing.

This is the error I get:

T* boost::shared_ptr<t>::operator->() const [with T = gazebo::physics::Joint]: Assertion `px != 0' failed.

Can anybody tell me what it means?
