Microcontroller based floor cleaning robot

Abstract

Many of the robotic appliances are being used extensively. Here represents the technology that proposed the working of the floor cleaner using RF technology and GSM module. This robot works on the manual mode. It performs sweeping task upto 50m range. Here RF technology have been used to provide wireless communication between the user and the robot. In the existing system there were many disadvantages like it performs poor cleaning, costly, we need to preclean before using the machine and, it is carried out using wired communication. In the proposed method we have used five motors, one for cleaning and four for movement of wheels. All operations are controlled by PIC16F877A microcontroller. Microcontroller is the brain of robot where program is written and sensors are connected as input and actuators as output LCD is used to display the information in which direction of robot has been moved. In the manual mode the expected task is performed with the help of keypad. If any obstacle is detected then it sends message to the user’s mobile which is connected with GSM module. L293D motor driver is used to drive the motors. Five motors are used in this robot and this motors are controlled by the motor driver. The whole circuit is connected with the power supply.
