I'm trying to run: $ rostopic pub /pan_tilt_node/pan_tilt_cmd pan_tilt_node/PanTiltCmd --once 90 90 $ rostopic pub /pan_tilt_node/pan_tilt_cmd pan_tilt_node/PanTiltCmd --once 45 45

1

But it only functions once on the first pub command. Alternating values of the pan and tilt do not create any additional movement, although the node reports the parameters.

If I try to do both pan and tilt to - 90 --once -- -90 -- -90 I get a parameter error "--".

Example from: http://pharos.ece.utexas.edu/wiki/index.php/How_to_Control_the_Lynx_Motion_Pan-Tilt_Assembly_from_ROS
