Future robotic systems intended to be used for domestic housekeeping or elderly care should flexibly adapt to the environment which is uncertain and may fluctuate. However, the current robot systems for industrial domain can operate only in the limited environment and require the special knowledge of the robot motion instructors such as how to use the teaching-pendant and program robot motions. Obviously such requirements are not appropriate for home-use robots. This paper proposes a robot sequence generation method based on the robotizing strategy considering required adaptability to environmental fluctuations and task difficulty for humans and robots. With the proposed method, domestic housekeeping tasks can be classified into three types such as automated tasks with hand-guiding instruction when necessary, human-robot cooperation tasks, and manual tasks without using robot. Then, it is shown that robot motion sequence can be described by a unified framework. The proposed framework is an extension from the one for in-situ robot motion modification method by hand-guiding instruction which was already proposed by the authors. The proposed method is actually applied to a sequence of cooking tasks and experiments are conducted by using a lightweight pneumatic robot arm. The experimental results show the effectiveness of the proposed method.
