Androids

An Android is a non sentinent robot or synthetic organism designed to look and act like a human, especially one with a body having a flesh-like resemblance.

The restriction of the term Android to non sentinent robots came about around the time the X101 species joined the Union. To distinguish themselves from the non sentinent Androids, they use the term Sentient Machines or Sentmac.

If an android body is directly controlled by a sentinent AI such as Mother Machine, or a biological brain it's considered to be an  Avatar.
