摘要
楼梯清洁机器人面向实际应用需解决最关键的问题之一是机器人在休息平台需走多久才决定下楼。针对该问题,研究发现机器人经过较多次对往下楼梯的探空,休息平台的清扫覆盖率已达到保证,此时机器人可以下楼。为此通过计算机仿真,采用随机路径规划清扫,以探空次数作为参数,分析探空次数与机器人在休息平台内清扫覆盖率的关系。仿真结果表明,清扫覆盖率与机器人探空次数呈指数型分布,并且与楼梯尺寸存在一定关系,并最终建立了覆盖率的数学模型,给出了最佳的探空次数,当机器人探空到该次数,便可下楼,实现从平台遍历到下楼的过渡。该方法成本低廉,为楼层清扫的连续性奠定了基础,有利于将成果推向实际应用。
One of the most critical problems that need to be solved for practical applications of stair cleaning robots is how long it takes the robot to clean a rest platform before deciding to go downstairs.In response to this problem, it was found that after many times the robot had gone down the stairs to the sounding, the coverage rate of the rest platform had been guaranteed and the robot could go downstairs.Through computer simulation, a random path planning is used. The number of soundings is used as a parameter to analyze the relationship between the number of soundings and the robot cleaning coverage rate in the rest platform.The simulation results show that the evolution of platform cleaning coverage rate expressed in the number of robot soundings has an exponential shape, and there is a certain relationship with the size of the stairs, then the mathematical model of the coverage rate is established.Finally, the best number of soundings is discussed. When the robot reaches this number of times, the robot can go downstairs and realize the transition from platform to downstairs.This method has low cost and lays a foundation for the continuity of floor cleaning, which is beneficial to push the results of this article to practical application.
