The gender of a word indicates whether it is masculine (male), feminine (female), or neuter (neither feminine nor masculine); for example: when the man (masculine) was hit by the ball, it (neuter) knocked him (masculine) down and his wife (feminine) helped him (masculine) get back on his (masculine) feet (neuter).

People and animals consist of female genders and male genders while things, objects, etc. are classified as neuter genders."

"These days, the use of the term gender is seen more often instead of using the word sex; such as, when identifying whether a person or an animal is a male or a female."

"When filling out forms, a person is usually asked for his or her age, income, and gender; so, now it seems that gender is being used to indicate a person's sex and sex is being used to indicate sexual activities."

An example of an android or a male robot. Yes, there are gender differences among the robots. They definitely should not all be labeled as androids.

An example of a gynoid or a female robot. Yes, there are gender differences among the robots. All robots should not be labeled as androids.

A genderless robot which does not have male or female characteristics should be referred to as a neuteroid which is a new term for this species of robots. This is the third of three gender differences applicable to robots. So, it should not be difficult to remember that not all robots are androids.
