The Head "Wobbler" Example randomly moves the head to demonstrate using the head pan and nod interfaces.
From an RSDK Shell, run the head_wobbler.py demo from the baxter_examples package:
Baxter's head will nod and begin panning left and right to random angles.
Baxter's head can move up and down in a nod_ motion, and rotate left-to-right in a _pan motion. The head nod motion is a single action that can be triggered to run, but cannot be set to a specific angle. The pan motion swings Baxter's 'face' (a.k.a. screen) to a settable angle, rotating around the vertical axes of the head.
The head wobbler example is intented to be a simple demo whose code can be examined to learn how to use the head and demonstrate the use of the baxter_interface Head class. The non-interactive demo calls the
command_nod() function and then sets the head pan to a few randomly generated angles, waiting in between each in order to give enough time for the head to move there.
