automatic book picking robot for libraries
TRANSCRIPT
Automatic book picking robotfor Libraries.
IntroductionTo automate the process of book finding and picking we suggest a robot with an arm with some degrees of freedom which will be able to find out the book with the required tag and then pick it and place it on the table.
DESCRIPTION
Here we will be placing the books in a rack and all the books will be tagged by RFID tags and an RFID reader will be used to detect the books .The IR obstacle sensor placed over the arm detects the book and then the gripper will close the jaws to get an hold of the book and then the robotic arm is lifted after which the robot moves in the reverse direction to the place it started from and places the book.
Features:
This projects contains 3 main parts:
Moveable base. The base shaft. Gripping mechanism.

Block Diagram Description
The main centre part of the project is the microcontroller. Here we are using the 8051 based Philips P89V51RD2 microcontroller. The P89V51RD2 are 80C51 microcontrollers with 64kB flash and 1024 B of data RAM
• LCD:
A liquid crystal display is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCs). LCs does not emit light directly.
• P89V51RD2 Microcontroller:
• RFID Reader and Tags:
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
IR sensors are nothing but infrared sensors, which have two semiconductor LEDs which sense the obstacles.
• IR obstacle sensor:
• DC motors:
In this project DC motors is used for rotating wheels of the robot and control the arms & Wheels of the robot.
• L298N Motor Driver:
In this project we are using L298N motor driver to drive 4 dc motors of our robot (4 wheels of the base). Only one IC can control 4 motors at a time.
• L293 Motor Driver:
In this project we are using L293 motor driver to operate two motors. One is JAW ROBOT DC MOTOR and the other is NECK ROBOT DC MOTOR.
• Zigbee Transceiver:
Zigbee provides reliable, wireless data communication. ZigBee is based on an IEEE 802.15.4 standard.
SOFTWARES USED:
Keil Flash magic Microsoft Visual Studio
Our project software (Using Microsoft Visual Studio)
Advantages: Reduces human effort Reduces human error Makes the management of the library, easier than ever. Saves time.
Disadvantages:• Problems of mechanical functioning may
occur• Capability of lifting a book has limitation.
Applications:• It is used in libraries of school,
colleges.• In big book stalls in malls.• News Paper printing press for
picking bundles of papers.• It may be used in paper mills.• Book exhibition & sales.• Central Libraries etc.
Conclusion:• In this Project, the proposed robot will make the
life of the librarian a lot simpler• To automate the process of book finding and
picking we suggest a robot with an arm with some degrees of freedom which will be able to find out the book with the required tag and then pick it and place it on the table.
• The same principal can be used in the supermarkets to make an automated item collector.
• Hence we use this system to avoid human errors, to save time & Money.
