4. INTRODUCTION -
 . Do you want to monitor various things at some remote
place where a human being cannot go? Do you think that is
it possible ?
 Yes, it is possible by making use of a mobile robot. How
wonder if it is a wireless!
 The current design of the ‘wireless floor cleaning robot’ is an
application of that which does the above mentioned things
for you.
 The design is based on 8051 micro controller and various
interfaces like Rf, dc motors etc.

7. WORKING -
 The whole system consists is divided into two modules, the TX
module and the Rx module.
 The TX module is simply a PC where software will be designed
with appropriate hardware for the controlling the robot.
 The robot moves in various directions as per the switching action at
the transmitting side.
 The different key press generates different RF signals. The Rx
receives these signals and moves accordingly.
 But the important thing to be noted here is that there is no
connection between the TX and Rx section. RF makes this task
very simple.

8.  The RF sends a signal to the micro controller at the Rx
side as soon as any key is pressed at the TX side.
 Now the micro controller at the Rx side rotates dc
motors to make the robot move in various directions.
 Here a mechanical arrangement is provided for the
actual appearance of the robot.
 And also the robot is mounted with a vacuum cleaner
which can be controlled wirelessly.

12.  BLDC motors
 Brushless DC electric motor (BLDC motors, BL motors) also
known as electronically commutated motors (ECMs, EC motors)
 These are synchronous that are powered by a DC electric source
via an integrated inverter/switching power supply, which
produces an AC electric signal to drive the motor
 We are using this motor in vacuum cleaner for cleaning the floor.
12

13. Radio Frequency Technology
 Radio frequency (RF) is any of the electromagnetic wave
frequencies that lie in the range extending from
around 3 khz to 300 GHz , which include
those frequencies used for communications or radar
signals.[1]
 It has one transmitter part and receiver part
 Transmitter part have RF TX module and receiver has
RF RX module.
13

14. SOFTWARES USED
 A Cross compiler for compiling and linking the code
written for 8051.
 Serial communication software for downloading code
to 8051.
 Operating System: Windows.
 Application program development in Embedded C.
 Proteus for virtual circuit simulation.

15. ADVANTAGES -
1. Wireless control
2. It saves time
3. It can clean ,where we cant clean like under the bed .etc
4. It can clean floor from standing or sitting one place
5. Ideal for people with mobility issues
15

16. DISADVAANTAGES -
1. Quality of clean
2. Expensive
3. Limited range of working area from laptop or pc
4. It should be range of your eye
16

17. APPLICATIONS -

19. CONCLUSION
 This project efficient floor cleaning with sweeping and mopping
operations. This robot works in manual for user convenience... RF
modules provide wireless communication between remote and
robot and their range is 50m. it sends the information to the
remote which gets displayed on tv or laptop. A wiper is connected
to it can wash the water in the for mopping purpose for the
convenience of user. User can also operate this robot manually
with the help of remote. It reduces the labor cost and saves time
also and provides efficient cleaning. In automatic mode, the robot
operates autonomously. The operations such as sweeping,
mopping and changing the path in case of hurdle are performed
automatically.
