• Automatic floor cleaner is an electronics home appliance which work on two modes automatic and manual.

• It performs two operation sweeping and mopping.• It can be use in crowed place like bus stands, railway station,

airports etc.• Most cleaning machines use a vacuum as the principle

cleaning device, but in our case, the cleaning device has been adapted from a commercially available electric broom.

• Cleaning the floor, especially in the kitchen, is one of life's annoying little chores that must be performed on a regular basis in order to avoid a buildup of debris. The standard method for floor cleaning relies on sweeping the floor and thereafter running a damp cloth or a mop across the swept floor. While tried and true, this method is time consuming and labor-intensive which result in “scheduled” floor cleanings being skipped for other less onerous tasks or even for a beer and a movie depending on the circumstances.• In order to overcome the time and labor intensity associated with floor cleaning, automated floor cleaning systems have been proposed. Such systems generally fall into one of two broad categories. The first type of such system relies on various sensors and artificial intelligence in order to systematically move the floor cleaner across the floor. The sensors detect objects and other obstructions and the artificial intelligence system determines the course of action of the device with respect to the object or obstruction. Advanced devices rely on neural networks or other learning algorithms in order to understand the topography of the floor for future cleanings of the floor

Applications• The main application of this circuit is that we can

control any appliance by just being in our living room. • This is very much helpful for elderly people as well as

for those who are unable to walk either due to physical disabilities or due to accidents.

• Another major use of our project is that we can turn off the operating devices all together at one shot by just pressing the power button.

Advantages• Time saving as it is operated by a remote.• Controlling all devices from one place.• More secure as there is no direct contact with the appliances.• Very effective for household needs.• Eco-friendly and produces less noise pollution.• No need of any type of remote control.

Conclusion Hereby we come to an end of or project “remote controlling of home appliances”. This project gives us an idea of RC5 Protocol and the microcontroller AT89C2051. This project can be used anywhere either at home or offices. This is also cost efficient. Thus by this attempt of ours the ON/OFF processes of many devices was successfully carried out by just using a TV remote.
