1. An apparatus, comprising:
a robotic limb, comprising:
a first limb segment;
a second limb segment; and
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 of the first limb segment aligns with an axial centerline of the second limb segment, 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 wherein the first joint further comprises a wire pass-through comprising a hollow shaft at each end of the first joint.
