Autonomous Lavatory Cleaning Robot

Health related issues are increasing day by day. New diseases are being identified in different places of India. One of the main causes of spreading diseases is unhealthy public toilets. There is a huge risk to get infected by various diseases while using such toilets. Unfortunately the mind set of people to keep toilets clean and hygienic is very poor. The negative approach of people is beyond our control. The idea presented in this paper seeks to provide a convenient and a hassle-free means of cleaning public toilets whilst maintaining hygienic and sanitary standards. Automatic Lavatory or Toilet cleaning robot is designed for the purpose of keeping lavatories hygienic in both public and private organizations and to replace the human effort to do such dirty jobs. It is automatically controlled using a Arduino UNO micro-controller, it is a three wheeled robot actuated by a DC gear motors, it travels in the predefined path (black lines)parallel to the mount toilet and takes cleaning action only when no human is present in the toilet using PIR sensors also avoids obstacles when found, it contains a movable mechanical linkage to produce motions which support the rotating brushes to clean the solid waste in toilets, also metering pump are employed to spray detergents/soap oil to the flow at the beginning of cleaning process respectively.
