Introduction: AUTONOMOUS PLASTIC TRASH DISPOSALDRONE -THE TRASH-BOT

Picture of AUTONOMOUS PLASTIC TRASH DISPOSALDRONE  -THE TRASH-BOT

To build an

automatic trash robot using Arduino-microcontroller and special robotic technologies which detects and collects the plastic stuffs automatically and process it. So this reduces the requirement of manual clearance of plastic waste, to clean up this debris etc.

Step 1: INTRODUCTION

Picture of INTRODUCTION

Plastics are cheap, strong, and durable and offer

considerable benefits to humanity. They potentially can enhance the benefits that both medical and scientific technology will bestow to humankind. Thus the main idea of our paper is to build an automatic plastic trash picking robot which automatically detects plastic around the beaches and store them in a container for recycling process. So this reduces the requirement of volunteers and people to clean up this debris and this TRASHBOT will do the work of human. Thus using this robotic technology to develop an autonomous trash collecting robot will provide a drastic importance in the field of sanitation and preventing plastic debris

Step 2: ​HARD WARE REQUIRED:

Picture of ​HARD WARE REQUIRED:

ØArduino uno (Atmega 328 microcontroller)

Ø Motor driver shield (L2930 H-Bridge)

ØParallax Ultrasonic sensor (HSR04)

Ø DC Motor with gear

ØPick and place arm

Ø Robot body and track wheels

Ø Printed PCB boards

Ø Connecting wires

Ø Screws and Nuts

Ø Battery -12v

1.Arduino uno (Atmega 328 microcontroller

Atmel’s
ATMega328 8-Bit Processor in 28 pin DIP package. It’s like the ATmega168, with double the flash space. 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage.

2.Parallax Ultrasonic sensor

Ultrasonic sensor provides an easy

method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects

3.Motor driver shield (L2930 H-Bridge)

Run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D. These are perhaps better known as "the drivers in our Adafruit Motor shield". If you accidentally damaged the drivers in a shield, you can use one of these puppies to replace it.

4.DC Motor

A DC motor is any of a class of electrical machines that converts direct current electrical power into mechanical power. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor. Most types produce rotary motion; a linear motor directly produces force and motion in a straight line.

5.Robotic Arm

The robot structure consists basically of the robot body that includes arms and wheels. Some force such as electricity is required to make the arms and wheels turn under command. One of the most interesting aspects of robot in general is its behavior, which requires a form of intelligence.

Step 3: Proposed System

This guy have cheated. Its our project. He have stolen from us.
The block diagram was designed by me. I have all the primary documents. He just helped us in coding. But now, he have posted as if it is his own idea.

Damn those cables :-)

Very nice job you did there :-) Next part... modify it so it takes out the garbage cans :-)
