The software of behaviour-based algorithms was parted to several functional modules which represented different behaviours with different priorities.A basic algorithm with S-type arbiter and an improved algorithm with I-type arbiter were compared.The improved algorithm can reduce judging time and avoid some mistakes of the basic one.In mapping obstacles,the robot adjusted the spread angle according to different distances to obstacles in scaled vector field histogram(SVFH) algorithm,and then the robot turned more sharply in near obstacles than in far obstacles,which made the robot move more safely and smoothly in a cluttered room.
在射频识别(RFID)系统中,不可避免地存在碰撞问题,标签碰撞的解决对于标签的快速有效识别非常重要。提出一种基于粒子群优化的改进自适应分组和预发信号ASPS(Adaptive splitting and pre-signaling)的RFID防碰撞算法。首先建立ASPS防碰撞算法模型;然后借鉴粒子群优化算法的特点,通过将接收信号二维化,建立适合粒子群优化算法的模型,从而改进ASPS算法。实验表明,该算法运算时间短,处理碰撞的次数少,具有良好的实际应用前景。
