Design of a Chaos Phenomenon Exhibition System

Abstract

This paper introduces a design of an interactive machine named Chaos Phenomenon Exhibition System (CPES). The CPES is a mechatronics system that consists of 180 independent modules, and each of them is a 2-Degree Of Freedom (DOF) machine which can realize forward and backward stretch on the horizontal plane, and clockwise and counterclockwise rotation synchronously. With the help of some sensors, the CPES can exhibit the effect of chaotic changes via the movements of the 180 modules. In this paper, the hardware (includes the mechanical structure and the electrical system) designs were introduced firstly. Subsequently, an algorithm was proposed to control the modules movement for exhibition of the chaos phenomenon. Finally, some improvements were conducted based on system simulation and field debugging. The CPES has been exhibited in a science museum in China and it is admired by lots of audiences.
