A robot must be able to generate various skills to achieve given tasks intelligently and reasonably. The robot must first learn affordances to generate the skills. An affordance is defined as qualities of objects or environments that induce actions. Affordances can be usefully used to generate skills. Most tasks require sequential and goal-oriented behaviors. However, it is usually difficult to accomplish such tasks with affordances alone. To accomplish such tasks, a skill is constructed with an affordance and a soft behavioral motivation switch for reflecting goal-oriented elements. A skill calculates a behavioral motivation as a combination of both presently perceived information and goal-oriented elements. Here, a behavioral motivation is the internal condition that activates a goal-oriented behavior. In addition, a robot must be able to execute sequential behaviors. We construct skill networks by using generated skills that make action selection feasible to accomplish a task. A robot can select sequential and a goal-oriented behaviors using the skill network. For this, we will first propose a method for modeling and learning Bayesian networks that are used to generate affordances. To select sequential and goal-oriented behaviors, we construct skills using affordances and soft behavioral motivation switches. We also propose a method to generate the skill networks using the skills to execute given tasks. Finally, we will propose action-selection-mechanism to select sequential and goal-oriented behaviors using the skill network. To demonstrate the validity of our proposed methods, "Searching-for-a-target-object", "Approaching-a-target-object", "Sniffing-a-target-object", and "Kicking-a-target-object" affordances have been learned with GENIBO (pet robot) based on the human teaching method. Some experiments have also been performed with GENIBO using the skills and the skill networks.

주말 오전, 8시. 평소 같으면 조용했을 창원산업보건센터가 시끌시끌하다. 센터 테니스장에서 세탁봉사를 하는 날이기 때문이다. 창원산업보건센터 직원들은 익숙하고 능숙한 솜씨로 빨래를 하기 시작했다. 빨래를 하며 나누는 이야기에는 웃음이 넘쳤다.

초록기운이 완연한 봄이다. 마음은 이미 봄바람에 실려 멀리 날아간다. 즐거운 여행길에 꼭 동반해야 할 것이 있다면 바로 카메라. 큰 맘먹고 장만한 카메라를 들고 근사한 한 컷을 위해 떠난다. 그렇게 찍은 사진은 앰벌속에 간직되는 대신 웹에 전시된다. 사진인구가 늘어나면서 전문가들의 전유물로 여겨지던 SLR카메라도 일반화됐다. SLR카메라 커뮤니티와 사진 솜씨를 자랑하는 인터넷 공간이 큰 인기를 끌고있다.
