Approach to distributed micro robotic system. Development of micro line trace robot and autonomous micro robotic system

The distributed micro robotic system is a group robotic system, which consists of many micro robots. A mobile robot plays an important role in the distributed micro robotic system. In this paper, the authors propose two types of the micro mobile robot. One is a micro line trace robot that runs along a black line using a pair of photo-sensors. The other is a micro autonomous robotic system constituted by some micro mobile robots controlled by a simple logic. The micro line trace robot consists of a pair of photo-sensors, a pair of electromagnetic actuators and a programmable logic device, but does not include a battery and the interfaces between the controller and actuator. The micro mobile robot constituting the micro autonomous robotic system moves toward the direction of high illumination of light, and includes a battery and interfaces
