Patent ID: 7942221

Claim:
Walking bi-pedal robot, the robot comprising: a pelvis; a right leg, coupled with said pelvis via a right hip lateral angular joint and via a right hip antero-posterior angular joint, said right hip lateral angular joint enabling lateral angular motion of said right leg, said right hip antero-posterior angular joint enabling antero-posterior angular motion of said right leg; a left leg, coupled with said pelvis via a left hip lateral angular joint and via a left hip antero-posterior angular joint, said left hip lateral angular joint enabling lateral angular motion of said left leg, said left hip antero-posterior angular joint enabling antero-posterior angular motion of said left leg; a right foot, coupled at the distal end of said right leg via a right ankle lateral angular joint; a right foot cable, one end of said right foot cable being coupled with the exterior side of said right foot; a left foot, coupled at the distal end of said left leg via a left ankle lateral angular joint; a left foot cable, one end of said left foot cable being coupled with the exterior side of said left foot; a pelvis motor, coupled with said right leg, said left leg, the other end of said right cable and with the other end of said left cable, said pelvis motor producing mechanical motion for generating lateral angular displacement of said right leg and of said left leg about said right hip lateral angular joint and said left hip lateral angular joint respectively and pulling one of said left cable and said right cable according to the direction of said lateral angular displacement; a right leg motor, coupled with said right hip antero-posterior angular joint for generating antero-posterior angular displacement of said right leg; a left leg motor, coupled with said left hip antero-posterior angular joint for generating antero-posterior angular displacement of said left leg; a power source, coupled with said pelvis motor, said right leg motor and with said left leg motor for providing power thereto.
