The aim of this project is to design a Bluetooth controlled Robot to clean the floor which is capable of receiving the signals from android Mobile. It is very useful for cleaning the floors. By using Bluetooth module, we can direct and turn the system as the user needs. It works great and controlled manually based on the user convenience. Definitely makes cleaning easier and merrier while enabling anyone to build something rather than buy. In modern days interior decorations are becoming an important role in our life. Cleaning of floor is a very important one for our health and reduces the man power requirement. Hence our project is very useful in our day-to-day life. Microcontroller  is an open source, computer hardware and software company, project, and user community that designs and manufactures microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The controlling device of the robot system is PIC Microcontroller. DC motor along with driver circuit, Bluetooth module, water motor along with relay, is interfaced to Microcontroller. Mop is connected at robot body. We can control the robot using Bluetooth module by using android mobile phone. By using Bluetooth module, we can control the direction of robot and on/off the water motor for cleaning. Here relay works as a switch to ON/OFF the device. This data is fed as input to Microcontroller. Microcontroller reads the data and make the Robot to move according to the direction given by the Android mobile. To perform this intelligent task, Microcontroller is loaded with a program written in C language.            

The major features of this project are:

1. To clean the floor based on instruction from Android mobile.
2. Control Robot using Bluetooth Technology.

           

The major building blocks of this project are:

• PIC Microcontroller.
• DC motor with driver.
• Bluetooth module
• Water motor
• Relay.
• MOP.
• Crystal Oscillator.
• Reset Button.
• LED indication.

         

Software’s used:

1. PIC C compiler to write the program.
2. PICK IT2 programmer to dumping code into Microcontroller.
3. Express SCH for Circuit design.
4. Using embedded C language.
