WHY IS ANDROID LOGO DESIGNED LIKE THAT
{
Here is how Android's green robot logo came to be:
The logo came to life some three years ago when Blok and her design team at Google were told to create a logo for Android, something that would instantly reverberate with customers, easily recognizable. Also, Blok was told the logo had to include a robot. After studying all sorts of sci-fi toys, she drew inspiration from a surprising source - a restroom. After all, everyone has seen the sign on a restroom and the male/female figures are instantly recognizable. So that’s where the robot comes in, in the form similar to the drawings on restrooms
