Smallest Robot

Robot Misquito

A robot helicopter weighing less than nine grams has been unveiled in Japan.
Japan's electronics giant Seiko Epson believes its Micro Flying Robot is the world's lightest and smallest robot helicopter.

Weighing only 8.9 grams, the four-legged mini-copter is equipped with four micro actuators to drive two rotors and stabilising units that make it fly and balance in the air.

The prototype version unveiled at the International Robot Exhibition in Tokyo relies on an external power source but flies by remote control.
