Message
1.	Service robot with vision and flexible human interface I have interested in realizing a service robot which can interact with humans by speech, gesture, or sign language. The task of the robot is to autonomously move to a user, or specified place, and to recognize specified objects by interaction with the user, grasp them and bring them to the user. Because I have worked at the Electrotechnical Laboratory (national laboratory), and Osaka University, I would like to cooperate with related laboratories to achieve our goal.
