balance thereof



7,119,510 B2: Floor reaction force position
approximation uses similar approach in a way
that assumes the midpoint of the contact area to
be reaction point.
7,835,822 B2: Possible conflict with similar twophase system reflex phase/recovery phase
approach.
2010/0161116 A1: This method uses Finite State
Model to reduce the left and right shift of the
robot. Similar in the aspect that the robot moves
in a finite state to keep the balance.
