This paper describes an experimental method for evaluating the stiffness of a biped walking robot. A reliable procedure is proposed as based on a simplified version of Milli-CaTraSys (Milli Cassino Tracking System) with three wire encoders and two six-axis force-torque sensors. This measures both applied wrench and resulting compliant displacements. Experiments conducted on a prototype of the biped walking vehicle WL-16RII (Waseda Leg - No. 16 Refined II) under different dynamic conditions provided useful information for both design and control.
