I am using a simulated PR2 in ROS Indigo (Ubuntu 14.04). While running

roslaunch pr2_gazebo pr2_empty_world.launch

the head of PR2 turns back and the arms get twisted and rotates continously. Also it is not possible to control the simulated PR2 using keyboad teleop package. It was working fine untill all the ros-indigo packages were updated through synaptic package manager .

It happens when the pr2_default_controllers are up and running. Simulation with no controllers makes no issues.

arms colliding and looking back arms rotating

I'm not sure, but this could be caused by ros-controls/control_toolbox/issues/40.

Thank You. It was exactly the issue. Upgrading to 1.13.2 version of control toolbox solved the problem.
