A robot organizing purposive behavior by itself

For studying the mechanism of the brain, the synthetic approach is effective. The synthetic approach is to conjecture the mechanism of the target through constructing its model. Some 20 models of the brain were constructed for this study. One of them is described. The model includes the faculties of perception, memory, and action. Having these three faculties enables the model to realize highly intellectual behavior or self-organizing ability that cannot be realized by a model having just one faculty. The model was realized in the form of a robot which organizes purposive behavior by itself. This robot forms effective behavioral patterns to achieve the purpose through trial and error
