DIPSO incorporates the dynamic mutation, multi-subpopulations methods of IPSO, and changes the heights and the positions of the peaks by variable parameters and chaotic model. This algorithm uses multi-subpopulations to search for the highest peak in order to track the dynamic environments. Furthermore, DIPSO apperceives the changes of the environment by tracking the fitness value of the global optimal particle.

该算法是IPSO的动态版本，沿用了IPSO的动态变异策略、多子种群策略，在算法运行的过程中分别对环境进行参数设定型动态变化和混沌模型动态变化，利用多子种群分别对多个峰进行搜索，很好地实现了算法的追踪性能；对全局最优粒子进行实时跟踪，利用其适应度值的变化来发现环境的改变，并以此来引导群体对环境变化的感应。

The system adopts C8051F020 single chip microcomputer to realize the communication with the robot principal controller by means of serial port. With a compact structure, the performance of the system is unaffected by the installation position, so it can be assembled to other type of robots as a robot standardized component , in order to help the robot to complete the olfaction-related work.3. Inspired by the foraging strategies of animals, a strategy of odor source localization is put forward based on the animal predatory behavior. The strategy fuses the information of gas sensor, wind direction sensor and ultrasonic sensor etc. and integrates several good search algorithms such as Z-shaped search, upwind search and fuzzy neural network search and so on.
