Abstract :
This paper describes a new leg module for biped locomotors. We have developed a biped locomotor, WL-15 (Waseda Leg 15), which is applicable to various fields, such as medical, welfare and entertainment. WL-15 consists of parallel mechanisms such as a high stiffness, high positioning accuracy and easily calculated inverse kinematics. A walking control program is created on the basis of Simulink and RT-LAB executed on Windows NT and QNX target system. Using WL-15, dynamic walking with the step time of 0.8 [sec/step] to 1.92 [s/step] and turning step of 90 is conducted, and the effectiveness of WL-15´s parallel mechanisms is confirmed.
