I am following pr2_simulator tutorial.

  1. roslaunch gazebo_worlds empty_world.launch
  2. roslaunch pr2_gazebo pr2.launch
  3. roslaunch pr2_teleop teleop_keyboard.launch

Strangely, from pr2_teleop, only 'W' (forward) and 'S'(backward) keyboard operation work. Any idea for this problem?

Which version of ROS are you using?

I am using groovy.

Check that the controllers have properly loaded and there are no segfaults.

I am new to ros. Can you tell me how to check the controllers? (At least, I did not see any error message from terminal.)

I am using multiple versions. When I use fuerte, everything works fine. But groovy causes the problem.
