Abstract
In this study, a heuristic approach and the Enhancing Type microcomputer were paid to attention. The biped robot is designed referring to walking of human. This robot is made to walk on unleveled land, and fresh discoveries are tried by observing the movement. In addition, the observation is helped by using the function of the Enhancing Type microcomputer. The Enhancing Type microcomputer records in microSD from which the log of the connected sensor is inserted in the microcomputer. The biped robot is improved by using this sensor log and the observation result. It is an attempt said that the robot that can walk in unleveled land by repeating this cycle will be invented.
