Study On Design Of The Control System For Intelligent Mobile Robot

Intelligent mobile robot which possesses the function of perception environment,dynamic decision and planning, control and execution behavior can have a purpose mobile tofinish the appointed tasks in a few or no intervention conditions or in certain circumstances,and it has the path planning, navigation, information fusion and testing, independent decisionso similar to human activity artificial intelligence. It has characteristics of highly independentintelligence, including more discipline knowledge, good flexibility and strong environmentalperception of ability, so the study of intelligent mobile robots will promote the developmentof artificial intelligence, life sciences, and robotics. This paper has a design of robot controlsystem’s architecture, combining with the system function characteristics, designing thehardware and the software of intelligent mobile robot control system at last. The mainlycontent of this paper includes:(1) This paper introduces the subject’s background and significance and the developmentof intelligent mobile robot at home and abroad, it also analyzes the key technology ofcontroller, navigation, information fusion. This paper designs control system structure andanalyzes system function and control form, it uses the control form of “PC+AVR” and designsthe overall principle diagram of control system.(2) The hardware of control system which is divided into the upper body machine andlower body machine uses modular design. The upper body machine chooseshigh-performance notebook computer, the lower body machine includes the power module,the gyroscope module, a compass module, ultrasonic and infrared module, sports module.Choosing ATmega128chip as each function modules of the micro controller and designingeach module circuit, one module communicates each other through RS485which meets theelectrical standard for serial communication interface.(3) Control system’s software uses a structured combination of design andobject-oriented design methods, drawing each module of program flow chart, the programbased on the Windows operating system and VC development environment. According to theflow chart, designing program to meet respective function of the module. (4) Testing the correctness and reliability of control system’s hardware design andsoftware design of this paper through experimental verification of intelligent mobile robotcontrol system. The experiment proves each module can realize the function and achieves thestability of system.
