Before revision:  We propose a new soft robot skin that can detect human contact through thermal features. An electrically conductive pipe is interposed between graphite sheet that has high heat conductivity and softmaterial for cover compliance. Then the temperature of the water pipe is controlled by a heat source and a small water pump .  Besides, an observer for estimating heat flow is implemented;
After revision:  We propose a new robotic cover prototype that achieves thermal display while also being soft . Besides, an observer for estimating heat flow is implemented;
