3. Objective
The main objective of this project is to built a
autonomous robot that can scan the specified arena
and picks the objects and place them in a specific
place with out human interference.
4. What is Autonomous Robot?
Autonomous robots are robots that can perform
desired tasks in unstructured environments without
continuous human guidance.
7. Components
AT89C51
Power Supply
LCD Module
LM358 Op Amp
IR Sensors
Gripper Module
L293D Motor Driver
DC Motors
Stepper Motor
LED’s
8. Microcontroller
AT89C51 is an 8-bit microcontroller
and belongs to Atmel's 8051 family.
ATMEL 89C51 has 4KB of Flash
programmable and erasable read only
memory (PEROM) and 128 bytes of
RAM.
9. IR Sensors
IR transmitter is a light emitting diode,
that emits the infrared light.
IR receiver is a photo diode capable of
converting light into either current or
voltage.
The IR sensor is used for object
detection.
11. Gripper
This gripper is made from the
DVD-ROM stepper motor.
This is very simple mechanism.
One gripper if fixed and the other
is movable.
12. Modules used
LCD MODULE
DC MOTORS
ASSEMBLED ROBOT
8051 MAIN BOARD
MOTOR DRIVERS
TACTILE SWITCH
WHEELS
GRIPPER
IR SENSORS
CASTOR WHEEL
13. Power Supply
Work based on 5V regulated supply.
Supply is given through 12V DC rechargeable battery.
Contain rechargeable circuit also.
14. LCD Module
LCD (Liquid Crystal Display) screen
is an electronic display module and
find a wide range of applications.
A 16x2 LCD means it can display 16
characters per line and there are 2 such
lines. In this LCD each character is
displayed in 5x7 pixel matrix.
15. DC Motors
A DC motor is an electric motor
that runs on direct current (DC)
electricity.
16. Stepper Motor
A stepper motor is an electromechanical device which
converts electrical pulses into discrete mechanical
movements.
17. Motor Driver
L293D is a dual H-bridge motor driver
integrated circuit (IC).
L293D contains two inbuilt H-bridge
driver circuits.
18. Working
When it start’s it will scan for objects in the arena, if any
objects were found, it will pick it and follows the line until
it reaches it’s destination, then it will release the object at
destination and again goes into arena for scanning.
19. Software Implementation
The Keil software is a user-friendly software suite
to develop the ‘C’ code and test the same in a virtual
8051 environment.
20. Applications
This is applicable in the areas where the human
involvement is not required.
21. Limitations
As it cannot sense the type of object it will try to pick
any object present in the fixed environment.
It will scan for the objects even there are no objects
present in specific environment.
22. Future Scope
Our project can be further extended by adding the color
sensor or a camera to sense the color and type of the
object to be handled. With this the accuracy to pick the
particular object in the arena will be increased.
23. Conclusion
The development of this autonomous robots are very fast
now-a-days, so many new autonomous robots in different
fields were made.
