Classification: CPC B | IPC B

Claim 8:
9. An apparatus comprising:
a robotic limb, comprising:
a first limb segment;
a second limb segment;
a first joint connecting the first limb segment to the second limb segment in an in-line joint configuration such that when the first limb segment and the second limb segment are fully extended then an axial centerline-passing in a straight line through the first limb segment's entire length aligns with an axial centerline passing in a straight line through the second limb segment's entire length, wherein the first joint comprises a first dual-reduction Quasi-Quasi-Direct-Drive (QQDD) joint actuator and wherein each reduction of the dual-reduction QQDD has a reduction in a range between 10:1 and 100:1; and
a third limb segment, connected to the second limb segment by a second joint, wherein the second joint comprises a second dual-reduction QDDD joint actuator.
