Due to the popularity of To Heart's Multi, having antennae-like ears is almost universally understood (although, like the character in this picture, visible mechanical joints are another dead giveaway).
Sometimes the character is shown to be an android by some unusual accessory to cue the audience. (Technically they would be gynoids, if you're the kind of person who cares.) These androids could be male, but due to the fandom's preferences, most of them are sleek, sexy females. Of course, Japan being the worldwide leader in consumer electronics, androids are quite popular in that country.
While not unheard of in American shows ( My Living Doll, Small Wonder, Mann And Machine) the robot girl on American TV tends to be a gimmick or MacGuffin on which to hang a series concept rather than a character type in its own right. The robot girl is not necessarily a completely mechanical creation - the character type can encompass cyborgs, bioroids and even virtual beings. (Robotic males, on the other hand.) Despite how cute or sexy she may be, though, the Robot Girl is often a dangerous opponent in a fight, even if they're only created to do common household chores. Despite their artificial nature, Robot Girls are never - well, hardly ever - sexless they are at the very least cute as hell, and more often downright gorgeous, if not outright seductresses. Most commonly found in science fiction and Sentai shows, but not exclusively.
She's the Robot Girl, a staple character type in anime. She's gorgeous, she's sexy, and she's got a 50,000-mile warranty. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace.
