In this paper, we propose a method of visual recognition in cooperation with actions for automatic handling of clothing by a robot. Difficulty in visual recognition of clothing largely depends on the observed shape of the clothing. Therefore, strategy of actively making clothing into the shape easier to recognize should be effective. First, after clothing is observed by a trinocular stereo vision system, it is checked whether the observation gives enough information to recognize the clothing

... pe robustly or not. If not, proper "recognitionaid" actions, such as rotating and/or spreading the clothing, are automatically planned based on the visual analysis of the current shape. After executing the planned action, the clothing is observed again to recognize. The effect of the action of spreading clothes was demonstrated through experimental results using an actual humanoid.
