Sets a background (or foreground) image for the face/eyes of the robot. You can specify a duration or keep it until the action is cancelled, and animation are also supported. See Background and overlays for details.
Quick snippets#
Send a goal from the command-line#
$ rostopic pub /robot_face/overlay/goal hri_actions_msgs/FaceOverlayActionGoal # press Tab to complete the message prototype
How to use in your code#
Call the action from a Python script#
#!/usr/bin/env python
