The new kind of gait for humanoid robots has been presented in the IROS ’08 (M. Arbulu et. al.).
It has been developed and implemented in the HRP-2 humanoid robot by a member of the roboticslab, during its research stage in the AIST (National Institute
of Advanced Industrial Science and Technology), Tsukuba, Japan (Sept.-Dec. 2007).
It was an honor for me to contribute of the roboticslab development.
