Abstract: A method for information transmission with backbone network and a position monitoring system for multiple robotic devices are provided in the present invention, wherein positions of multiple robotic devices disposed and operated in a widespread area are capable of being monitored. The present invention provides a plurality of positioning and transmitting modules for constructing a backbone network for transmitting position information. The positioning and transmitting modules disposed in the positioning area functions to identify the position of robotic device disposed therein and then report the position information to a central managing unit located in the monitoring center through the backbone network. By means of the foregoing method and system, the monitoring center can monitor the position of the plurality of robotic devices and dispatch orders and assign jobs to those robotic devices in a way of distributed and cooperative multitasking.

Abstract: The present invention provides an apparatus with surface information displaying, wherein a skin unit comprising a flexible display is covered on the surface of a moving object of the apparatus such that the surface of the apparatus is capable of displaying the information such us color, pattern or text immediately by software control. Meanwhile, the flexible display further has a layer of tactile sensing unit for detecting input of interacting signal. In addition, the moving object further integrates an environmental sensing device, an information identifying device or a combination of both and uses the environmental status, text information or audio/video, which are generated from the environmental sensing device or information identifying device, as an input signal through cable or wireless technology so as to generate responsive action through the flexible display or mechanism of the apparatus so that interactivities of the apparatus can be increased.
