Balancing Act
This video features the BalBot Advanced in standard "Balance Mode", so it acts just like a BalBot Basic.  It will try to balance itself, and react to outside forces when necessary -- doing whatever it takes to keep itself balanced.  If you listen closely, you can just barely hear the quiet motors above the background noise.

Note that the Basic and Advanced versions would perform exactly the same way in this demonstration.
