In this paper a coordinate transformation is proposed that provides an inertially decoupled structure for the equations of motion of a floating base robot. As the center of mass (CoM) has been used both for locomotion and balancing of legged robots because of its decoupled dynamics from the rest of the system, we expect to benefit ...
