Blake-
Try echoing the fingertip pressure topics and make sure you're getting
data:
rostopic echo pressure/r_gripper_motor
If the data is all zeros, or "-1", then the sensors aren't hooked up
properly. Can you post the output of that topic?
Moving to pr2-users, since fingertips are installed on PR2's
