Mopping module design and experiments of a multifunction floor cleaning robot

The autonomous cleaning robot has entered the practical stage, and is getting more and more popular. Currently most researches of the cleaning robot focus on sensor technology, location and environment modeling theory. And these researches have made great progress, which proves the practicability of the cleaning robot further. In this paper, we firstly propose a novel method to mop the floor by using a sponge, and use this method to design a mopping module in the frame work of a multifunction floor cleaning robot. Then the parameters of the module are optimized by analyzing the amount of the pumping out and recycling water. Lastly, a real experiment is carried out to validate the method's effectiveness.
