Humanoid robot with a central region having an arrangement of actuator assemblies and components

A humanoid robot comprising:

• an upper region including a head, a torso, and a pair of arms coupled to the torso, and wherein the torso includes a lower torso width that extends between a first lower point located within a lower extent of a first side of the torso and a second lower point located within a lower extent of a second side of the torso;
• a lower region spaced apart from the upper region and including a pair of legs;
• and,
• a central region interconnecting the upper region and the lower region, the central region configured to allow movement of the upper region and the lower region relative to one another, the central region including:
• (i) a spinal actuator assembly having a spinal pivotal axis that is oriented orthogonal to an upper housing surface of the spinal actuator assembly when the humanoid robot is in an upright, standing position;
• (ii) a rear support frame member coupled to a left hip yaw actuator, a right hip yaw actuator, and the spinal actuator assembly;
• (iii) a pelvis width that extends between a first point located on a lateral outermost extent of the left hip yaw actuator and a second point located on a lateral outermost extent of the right hip yaw actuator, and wherein the lower torso width is greater than 67% of the pelvis width.
