Title: Balancing Made Simple Abstract: This talk describes some basic principles that can be used to simplify the problem of balancing, and to achieve high-performance balancing in the sense that the robot can make large, fast movements without losing its balance. These principles are: (1) treat balancing as a physical process instead of a control theory exercise; (2) express the balancing behaviour in a simple form; (3) seek to control the balancing behaviour only; and (4) lean in anticipation of future commanded motions.
