Service Robot Development with Design Thinking

This paper described about design method using design thinking by collaboration with designer and engineer for the service robot development. A service robot does not have the substitution function what does the thing a person can't do in concerning with a person. It's necessary for a service robot to create to be able to do because it's a robot. This research aimed at the light in outdoor. This made the watch function as well as the role as the illumination last, and the feedback which isn't robot-like was shown by the illumination pattern. The relation between an expression of illuminations and the feeling was examined using psychophysical method to express the function as an expression of illuminations by this illumination pattern. Developed illuminations could mount a function expression as watch and offer more solutions by data and a sensing.
