00043     Record timestamped joint and gripper positions to a file for
00044     later play back.
00045 
00046     Run this example while moving the robot's arms and grippers
00047     to record a time series of joint and gripper positions to a
00048     new csv file with the provided *filename*. This example can
00049     be run in parallel with any other example or standalone
00050     (moving the arms in zero-g mode while pressing the cuff
00051     buttons to open/close grippers).
00052 
00053     You can later play the movements back using one of the
00054     *_file_playback examples.
