In this paper, a novel stress relief robotic system is designed to help people release their stress. Such a system should have good interactivity, that is, the robotic system can respond to various user input such as touch and voice by playing audio, video and so on. Besides interactivity, the robotic system should also have good application scalability. Good application scalability means developing and integrating a new application into the system should be easy without modification to the structure of the system. This is due to the fact that users in different situations need different applications to release their stress. The robotic system in this paper is designed to be capable of responding to touch and voice and providing good scalability. The robotic system is mainly made of a multi-touch interface based on diffused illumination technology, a microphone to receive voice, a projector to show screen on the interface, and a PC as main controller.
