Robotic Surface Treatment Device

Abstract

A robotic surface treatment device includes at least two wheels, at least two electric motors, wherein one electric motor is connected to one corresponding wheel via a motor shaft, at least two treatment pads, wherein at least one treatment pad is attached to a bottom surface of a corresponding wheel, a main controller positioned on top of and in connection with drive controllers positioned on top of each electric motor, a plurality of sensors integrated in the main controller, and a rechargeable battery connected to the main controller. At least one treatment fluid tank may be positioned on the robotic surface treatment device, and at least one treatment fluid tube may extend from a bottom surface of the treatment fluid tank to a bottom surface of the robotic surface treatment device. The sensors may be laser or acoustic sensors configured to create a boundary line for a treatment area.

AI Technical Summary

Benefits of technology

The invention describes a robot that can clean surfaces. The robot has two wheels, and it can move in different patterns. The first wheel can rotate faster than the second wheel, which causes it to move in a straight line. This allows the robot to easily move around and clean surfaces.

Problems solved by technology

Development of an effective robotic surface cleaning system that can clean any hard surface (e.g. concrete, tiles, vinyl, hardwood, or any combination of these materials) remains difficult to achieve.

The state-of-the-art autonomous or tele-operated, robotic or manual (local or controlled) surface cleaning systems that are commercially available for domestic or industrial surface cleaning applications are still ineffective in comparison to common, hand-held mops.

These commercially available, wheeled, surface cleaning systems are extremely limited in their ability to properly clean a surface.

These systems are incapable of rubbing or pushing the cleaning tools of the system (a cloth or brush) with the requisite amount of pressure necessary for removing dirt, grease, mud, or any other substance from a hard surface.
