Research on extension element model of robot

After having analyzed robot systems, this paper presents a method of organizing robot system with the matter-element in extension theory. The robot physical structure determines the matter-element model of robots. The objective external environment where robot is placed is plentiful, but the information that the robot can get about objective external environment is limited. The sensors carried by the robot is the only source of information. The sensor data can describe a robot external environment. The move, how to move, movement direction and movement mode of the actuators on the information obtained by the sensors closely relate to external environment. If we ignore the sensors and actuators in a robot system, the robot system is a processor and controller with moving targets and motion control rules. The moving targets is an active control system that is independent. In an extension element model of robots, the sensor data describe the inputs of robots, the movement of actuators describes the outputs of robots, and the robot itself is a controller with moving targets and motion control rules. The study on the matter-element models of robots can develop new research methods and ideas of robots, which is important for the robot's development and application.
