In　order　to　explore　the　cognitive　mechanism　and　simulate　the　cognitive　ability,　we　develop　an　artificial　sensorimotor　system　with　operant　conditioning　function　(ASSOCF)　to　improve　the　cognitive　and　intelligent　ability　of　robots.　The　system　reproduces　the　biological　motor　cognition　by　simulating　the　sensorimotor　system　and　realizes　the　mapping　from　perception　to　action.　Meanwhile,　the　system　is　endowed　with　operant　conditioning　function　based　on　Skinner＇s　operant　conditioning　theory.　It　forms　the　close-loop　system　between　perception　and　action　in　compliance　with　the　logic　of　＇stimulus-response-reinforcement＇.　Two　classic　experiments　in　behavioral　psychology　and　control　theory,　Skinner　pigeon　experiment　and　Wiener　worm　experiment,　are　performed　to　testify　the　validity　of　the　system.　Comparisons　of　the　experiment　results　prove　that　the　system　successfully　simulates　the　biological　sensorimotor　system.　With　such　a　system,　the　robots　are　endowed　with　the　abilities　of　autonomous　learning　and　self-adaptation　to　the　environment.　©,　2015,　South　China　University　of　Technology.　All　right　reserved.
