• an exhaust vent opening:
• (i) positioned above to the upper reference line, (ii) rearward of the coronal plane of the robot, and (iii) having an inner surface;
• an exhaust fan positioned within the torso and configured to force air out of the exhaust vent opening, and wherein a gap is formed between the exhaust fan and the inner surface of the exhaust vent opening;
• an intake vent opening positioned below the rotary left arm actuator;
• an intake fan positioned within the torso, below the rotary left arm actuator, and configured to force air into the torso.

A humanoid robot comprising:

• a waist;
• a torso:
• (i) having a side portion, (ii) a battery pack, and (iii) a vent opening located in said side portion of the torso;
• a processing unit positioned within the torso and coupled to a heat sink, and wherein the heat sink is positioned between the battery pack and an inner surface of the torso;
• and
• a fan positioned within an extent of the torso and proximate the first vent opening, wherein said fan is configured to generate an air flow path that primarily flows along the side portion of the torso and is positioned between the processing unit and an inner surface of the torso.
