Kimagure Robot

Overview

A brilliant, slightly crazy, and extremely eccentric scientist toils away his days in his lab, creating robots to carry out different tasks. A robot to grant three wishes, a robot to help you write your diary, a robot that intentionally misbehaves in order to keep its master from becoming bored… the robots are each built for a very specific purpose, and can’t really do much of anything else. Luckily for mankind, however, these robots are much more useful than they appear to be at first glance… most of the time, anyway. (Source: Anime News Network)
