Algorithm Research And Implementation In Home Service Robot For Searching Objects

With the development of the society, aging increasingly acute problem has become a worldwide trend. As the rapid development of science and technology, countries had looked into the study of household intelligent service robot to alleviate the pressure of the growing aging population.In this paper, focusing on implementation in simple household space, intelligent service robot AS- UIII under the designed program to complete item search tasks and avoid obstacles. Through analysis the principle of the intelligent service robot AS-UIII and test of each sensor, preliminary to master the use of mixed performance.Compared to today's item search task of advantages and disadvantages of each algorithm design, in this paper we selected items for PID control algorithm in the process of finish goods search and the function of obstacle avoidance.First of all, through analysis the residential environment of intelligent service robot working,combine with the intelligent service robot performance of each sensor, then set up the household space model so as to simplify the algorithm and the program design.Second, we get the experimental data through master service robots AS-UIII circuit principle and structure of each sensor performance then obtained by analyzing the error of the test.Again, through the study of the trace of the experimental data and the data processing in Matlab simulation analysis the rationality of the design of algorithm. After analysis of the data is applied to the design of PID control algorithm in the program and load to the AS- UIII, observe the experiment result, get a more reasonable experience coefficient of PID control algorithm.Finally, in the interface of VJC2.0 design control tree in the AS- UIII include obtain distance,obstacle avoidance,photo taxis.Then get the corresponding code by compiling in the KEIL projects. After modify and embedding of each subroutine,loaded into the intelligent service robot AS- UIII, running the program and observation the state. Aiming at all kinds of situation, analysis and ruled out one by one, in the interface debugging repeatedly within each operation parameters to make the best operation, and achieve ideal item search results.
