Abstract

The world today faces major garbage crisis- the product of rapid economic growth, overcrowding, poor urban planning, corrosive corruption and political dysfunction. The present tried and tested methods of garbage collection have so far been proven ineffective. And the world today is looking at smarter ways of overcoming the garbage collection problem. This paper presents the Garbage Collector robot for foot path using Arduino microcontroller. The robot is built on a metallic base of size 50x40 cm which is powered by battery of 12V, 7.5Ah. The robot movement is controlled by programming the Arduino. The robot is designed to collect Garbage at foot path, public places (parks, schools and colleges), mostly cemented paths and beach. The robot cannot be used on muddy surfaces. The robot is built in such a way that, when it is started it will move on the path defined in the program. When it encounters the obstacle, depending on the conditions applied in the program the bot proceeds with further motion and then robot picks up the garbage.

1. Introduction

Garbage is the major problem not only in cities but also in rural areas of world. It is a major source of pollution. Many cities alone generate more than 100 million tons of solid waste a year. . There are already different type of garbage collection robots [1-3] like Robo-dumpster which mainly aims at collecting garbage from full cans and dispose it designated area and Dust cart which is designed to navigate through urban areas avoiding static and dynamic obstacle and waste door to door. These robots which are in use have various disadvantages like high implementation cost, not user friendly and aims at only collecting filled dustbins but not on collecting mechanism, etc. Also, Municipal solid waste workers (MSWWs) or refuse collectors, universally expose too many work related health hazards and safety risks, notably allergic and other diseases of the respiratory system. Health impacts could also entail musculoskeletal, gastro intestinal and infectious diseases as well as injuries caused by work-related accidents. Hence to overcome this major problem of waste collection Autonomous Garbage Collection robot is developed. It aims at providing automatic control to collect the garbage. It differentiates

between static and dynamic obstacle and move accordingly as it programmed. It basically consists of sensors at different levels to detect the dynamic obstacle. It also disposes the garbage to a pre-specified place. If the trash bin is filled, it will be detected and the garbage will be disposed.

2. Literature review Until recently, robots were mainly used in factories for automating production processes. In the 1970s, the appearance of factory robots led to much debate on their influence on employment. Mass unemployment was feared. Although this did not come to pass, robots have radically changed the way work is done in countless factories. This article focuses on how the use of robotics outside the factory will change our lives over the coming decades. New robotics no longer concerns only factory applications, but also the use of robotics in a more complex and unstructured outside world, that is, the automation of numerous human activities, such as caring for the sick, driving a car, making love, and killing people. New robotics, therefore, literally concerns automation from love to war. The military sector and the car industry are particularly strong drivers behind the development of this new information technology. In fact they have always been so. The car industry took the lead with the introduction of the industrial robot as well as with the robotisation of cars. The military, especially in the United States, stood at the forefront of artificial intelligence development, and now artificial intelligence is driven by computers and the Internet. In relation to household robots, we see a huge gap between the high expectations concerning multifunctional, general-purpose robots that can completely take over housework and the actual performance of the currently available robots, and robots that we expect in the coming years. In 1964, Medith Wooldridge Thring predicted that by around 1984 a robot would be developed that would take over most household tasks and that the vast majority of housewives would want to be entirely relieved of the daily work in the household, such as cleaning the bathroom, scrubbing floors, cleaning the oven, doing laundry, washing dishes, dusting and sweeping, and making beds. Thring theorised that an investment of US$5 million would be sufficient for developing such a household robot within ten years. Despite a multitude of investments, the multifunctional home robot is still not within reach. During the last ten years, the first robots have made their entry into the household, but they are all ‘one trick ponies’ or monomaniacal specialised machines that can only perform one task. According to Bill Gates may be on the verge of a new era, when the PC will get up from the desktop and allow us to see, hear, touch and manipulate objects in places where we are not physically present.

3. Methodology In the present paper, the design of garbage collector robot uses engineering method. In sequence, the method is identification of the needs required. Then these needs are analysed to get specific components. These components are later integrated to get the desired output. The basic methodology is as shown in figure .The operation of the robot can be classified into three main categories. They are motion control of the robot, garbage collection and disposal of garbage.

Locomotion of the Robot

The robot can travel in the predetermined path by using a combination of motors, drivers, and sensors connected to the Arduino. This system consists of four geared motors of 30rpm each, motor drivers and three ultrasonic sensors. The ultrasonic sensors act as input to the Arduino. The motors are connected to the output of the Arduino through the drivers. The ultrasonic sensors detect the obstacles and the motors are made to rotate based on the pre-programmed instructions in the Arduino.

• Garbage Collection The robot Garbage collection system consists of a set of rotating blades mounted on a shaft connected to the motors. The mechanism will not operate for entirety of the vehicle operation and will rotate only for predetermined set of conditions. The rotating blades may be made of galvanised iron or stainless steel to suit outdoor applications as well as durability. The main aim of the mechanism is to collect garbage which is of similar dimensions to that of juice cartons, plastic bottles, crushed papers, and all light items whose height is between 5 to 20cms. Mechanism is mounted on the front side of the base with an appropriate ground clearance. Two motors are mounted on the two sides of the shaft and is connected to Arduino to perform rotating mechanism. The collection mechanism is built is such a way as to suit public places like gardens, bus stands, footpaths. When the sensor detects static obstacle, the mechanism rotates and the garbage is pushed into a bin which is placed right behind the mechanism. The robot keeps collecting the garbage until it reaches certain height in the bin. Once the bin is filled the collected garbage is disposed to a selected place.

•

Disposal of Garbage

This action is done using tilting mechanism. The speed of the motor attached to shaft is kept at nominal value to get proper rotating action to move the garbage right into the bin. This is just a prototype and hence the mechanism used can pick only above-mentioned garbage. The mechanism can be changed according to the place where it is being used

4. Objectives

The objective of the project is to achieve the garbage collected efficiently and effectively. The robot moves in a constant speed. The garbage gets detected when it is at 20cm from the trash.

5. Problem Statement Our goal in this project was to create a prototype automatic household cleaning robot capable of targeting specific objects, collecting them with a robotic arm, and depositing them in a receptacle. Current commercial cleaning robots, like the Roomba, are only capable of cleaning dust and small particles off the floor using random movement. We aimed to make the robot more intelligent in its cleaning procedure and make it capable of picking up larger pieces of garbage. To solve this problem, we determined the general components necessary for the robot to be able to complete its goals. A robotic arm is necessary to collect and deposit garbage of considerable size. Navigation was also needed to move the robot to search for and collect garbage as well as to avoid obstacles and return to the receptacle. Image processing is also necessary to differentiate obstacles from targets. Finally, interfacing was also required in order to seamlessly integrate these components together. Additionally, certain constraints were placed on our project to prevent the system from becoming unrealistic. A major concern was the strength and control of the robotic arm. The actuators that act as the joints of the robotic arm must be able to detect the position of the actuator with accuracy in precision. Accurate actuators are necessary in order to move the robotic arm as planned so we sought actuators that could find its position 100% of the time with no resistance.

In order for the robot to search for targets a distance away from the robot, the image processing of the robot must be able to recognize objects at least 4 feet away. In addition, the robot is required to operate in real-time or semi-real-time. This requirement dictates that the robot must not stop and hang up frequently. We assumed that the bottleneck of processing speed would be on the image processing because image processing requires significant amount of processing power. Therefore, we required that the image processing must be capable of running on the robot Our goal in this project was to create a prototype automatic household cleaning robot capable of targeting specific objects, collecting them with a robotic arm, and depositing them in a receptacle.

Therefore, we required that the image processing must be capable of running on the robot with a processing speed of at least 5 images processed every 4 seconds.In addition, constraints were placed on the operating environment to allow for consistent and controlled tests. Adequate and stable lighting had to be present in the environment to produce consistent, clear images for the camera to capture. In addition, the target objects were limited to soda cans that must be empty or closed; else during arm retraction the can would spill its contents onto the robot itself. Obstacles also need be a certain height so that patterns on the ground could be ignored. For our prototyping purposes, we created stages that were of limited size and with an accessible target and receptacle to allow the AGCR to complete its task without running out of batteries or indefinite roaming..

7. Working and Circuitry

Some of the system requirements of the project are listed below: Motor driver circuit is used for the motion of the robot. Power supply as to get sufficient power for the motor. The robot requires a motion controlling unit i.e. Arduino Uno kit with adapter. Automatic motion of robot is obtained by using sensors in the navigation system. Metallic structure of the robot. Other auxiliary circuits are added as per the requirements. Arduino Uno is the controller that coordinates the functionalities of the three stages to meet the real-time requirements. Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

8. Design of the Robot A rectangle metal sheet of size 50 X 40 cm is taken as base of the robot. Four wheels are attached with geared motors to the base. The motors are of 30rpm each to move the bot to accurately detect the garbage. The mechanism of the bot has four which of are placed at an angle of 90 degrees from each other. The blades are fixed to a shaft. The blades rotate along with the shaft to collect the garbage. A curved metal sheet is placed below the blades so that the garbage is properly directed to the collecting box placed on the base. The collecting box has a tilting mechanism so that the garbage collected can be disposed to a specified place. There is another level on the base.

10. Scope of reasearch

The Garbage and recycling pickup work is physically demanding and it exposes workers to many occupational hazards. This project is designed to fulfil the task of collecting garbage from certain places and then dispose it at a single place from where the garbage will then be taken for disposal or process of recycling. To build an automatic trash robot using Arduino microcontroller which detects and collects the paper and plastic items automatically and process it. So, this reduces the requirement of manual clearance of plastic waste.

11. Significance of study

The objective of the project was achieved to some extent. The garbage collected efficiently and effectively. The robot moves in a constant speed. The garbage gets detected when it is at 20cm from the trash. The project is still in progress to achieve the optimised results with few more modifications.
