DoggedLearning.mpg: Video of the Dogged Learning framework discussed
in Grollman and Jenkins (ICRA 2007) in action.  The Sony Aibo is
controlled by one of two programs, a teacher who knows how to search
for and approach the pink ball, and a learner who initially does not.
As the teacher acts, the learner learns and is eventually able to
perform the task on its own.
