Study On Avoid Obstacles And Path Planning Of Intelligent Home Services Robots

The development of robot technology is an important indicator of national hi-tech development level and the degree of automation. With the rapid development of sensor, automatic control, computer technology and material science; robot design and research forward to the third generation of robots - intelligent robot and gradually applied in the field of various service industries.This article firstly introduced service robot market demand and the development trend, pointing out that a key technology and existing problems, led to international cooperation projects - Intelligent family services Robot; described the research of path planning and obstacle avoidance.Secondly, In order to describe the architecture of Intelligent robot, I put the United States ActiveMedia's Universal P3-DX mobile robot platform as an example , introducts the mobile robot hardware and software structure and control structure.Thirdly, designed location systems based on ultrasonic ranging sensor; designed a piece of circuit board of measuring distance, after data acquisition, data processing, got the very accurate real-time location, make the foundation of real-time obstacle avoidance.Then, In the potential field model, using practical and simple method of artificial potential field set up gravitational field, repulsion field, the total potential field model, and then conducted a simulation test, the path planning algorithm implementation.Finally, improve the existing model to a new method, a new grid algorithm that improved the efficiency; use of the algorithm at work of the Center for Intelligent Biomimetic environment real-time exercise, it is successfully completed the mission.The results showed that this article discussed two methods to achieve a better path planning, and achieved good results, intelligent household services robot took part in the 10th Shenzhen "international high-tech fair," won the praise.
