How to control pr2 head in gazebo
Hi all,
I'm trying to control pr2's head (i.e., moving up and down, left and right) in simulation, but couldn't get it working. To this effort, I start with playing with controlling right gripper as in the tutorial ( http://www.ros.org/wiki/pr2_simulator... ). However, publishing a command does not seem to work (?!). It did not change anything. Actually I do not know what to expect..
Can anyone give me some directions of controlling pr2's head? Thanks a lot.
