Autonomous surface cleaning robot for wet and dry cleaning

摘要

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

1. A surface treatment robot comprising:
a robot body having a forward portion and a rear portion; a differential drive system mounted on the robot body and configured to maneuver the robot over a cleaning surface; a controller in communication with the drive system and configured to differentially steer the robot; a proximity sensor responsive to an obstacle forward of the robot, wherein the controller is configured to alter a heading setting in response to a signal received from the proximity sensor indicating a potential obstacle; a cliff sensor responsive to a potential cliff, wherein the controller is configured to alter the heading setting in response to a signal received from the cliff sensor indicating a potential cliff; and a passive scrubbing element disposed across a cleaning width of about 10 cm to 40 cm such that a shear force is generated between the passive scrubbing element and the cleaning surface as the robot moves over the cleaning surface, wherein an average drag force between the surface treatment robot and the cleaning surface is up to about 40% of the weight of the surface treatment robot and the surface treatment robot has a mass of less than about 10 kg.
