Electromechanical androids

One of two main varieties of androids.
Electromechanical androids (abr. Electro) have mechanical parts that function with the use of electrically-activated muscles, or actuators. They require the use of batteries and supercapacitors. Compared to biomechanical androids, electromechanicals have greater instantaneous power throughput, and depending on their fabrication, can withstand more pressure.
Electromechanical androids are usually destined for industrial work, and as such, their skin has fewer tactile sensors, if any, compared to biomechanical androids.
Another characteristic of electromechanical androids is that they are unable to express emotions (either real or simulated) unless specifically designed for. Certain models of female electromechanicals are able to cry, laugh and smile on demand, but they have been superseded by biomechanicals.
Electromechanical androids are most of the time built without sexual organs.
