Robotan

Household robot Robotan, made by a nerdy school boy named Kan-chan, lives with an everyday Japanese family as a domestic servant and friend to the children.

When a boy's uncle sends him confusing plans for a robot from America, the boy makes a mistake in the assembly which leads to unexpected results.

Apparently inspired largely by Akira Toriyama's popular Dr. Slump, Cybot Robocchi is the story of Robocchi, a fun-loving, mischievous robot with a TV set in his stomach. Robocchi lives in a peaceful village with various other robots, all created by the eccentric and somewhat lecherous Dr. Art Deko. Although he is an android, Robocchi has a warm, kind heart and is always willing to help out a friend in need. With his human girlfriend Kurumi, he gets into a variety of wacky adventures.

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.
