Biped Robot Leg's 3D Mechanical Design

3D Mechanical Design of Biped Robot Leg (6-DOF, Servo-Based) I need a complete 3D CAD model (STEP+STL) of a biped robot leg structure with 6 degrees of freedom (3 DOF per leg: hip, knee, ankle). This is for the N2-W emotional interaction biped walking robot project...
