Unmanned Floating waste collecting robot.pptx

The growing world is facing today is plastic contamination in river, pond, lake or any surface water.
Global plastic resin production was about 288 million metric tons in 2012 .Solid waste generation has also increased over the past five decades.
Human health is threatened tremendously by the plastic toxins that lead to cancers, congenital disabilities and immune system

2. What was the reason for making a robot like this? - PROBLEM The growing world is facing today is plastic contamination in river, pond, lake or any surface water. Global plastic resin production was about 288 million metric tons in 2012 .Solid waste generation has also increased over the past five decades. Human health is threatened tremendously by the plastic toxins that lead to cancers, congenital disabilities and immune system

3. SOLUTION Various attempts have been taken till date to materialize unmanned water robot technology. Here we are presenting a cost-effective remote-controlled robot with advanced control features that can assist the humans in removing the floating water waste safely and quickly making work easier and more sustainable.

4. Component of Unmanned Floating Waste Collecting Robot Atmega328p microcontroller based Arduino UNO Bluetooth communication module Rigifoam board Gear motors conveyor belt L293D Motor shield Driver Lithium Polymer Battery Water level detecting sensor

5. Ⅰ. DESIGN AND IMPLEMENTATION The material chosen for the body of the robot is rigifoam board keeping all the aspects in mind. The surface of the conveyor belt is roughened rubber surface and is chosen for its water repellent nature. The motors used are high-torque so that the water currents cannot force the motor to rotate. The water level detecting sensor use to stop the conveyor belt when the boat near to drowning level.

6. Ⅱ. CONTROL MECHANISM Control Unit The central processing unit of the floating waste collecting robot is an microcontroller based Arduino Uno. Bluetooth communication module is used for communication between the remote mobile phone and the unmanned floating robot.

7. B . Controller Design The controller is so designed that it takes instructions of propeller and conveyor belt movements based on Bluetooth signals. The controller also controls the power flow through to the different parts of the system. Fig.1. Functional Flow Diagram of Unmanned Floating Waste Collecting Robot

11. C . Power Control A3-cell lithium polymer battery is used as a power source which directly feeds the h-bridge controlling the motor. A switch-mode buck converter has been designed which provides the power to the 5V devices including bluetooth, control system, sensors and servo motor.

12. D. Propeller Mechanism Two propellers are used to provide the driving force for controlling the speed of the robot as well as the direction. Each of the propeller is connected to a 12V 300 RPM geared DC motor . E. Conveyor Belt Mechanism Designing the mechanism for collecting the floating rubbish is one of the major issues in the development of the robot. Moreover large volumes of trash needs to be collected at once. A 12V 120 RPM geared DC motor has been used for controlling the conveyor belt.

13. F. Trash Management The conveyor belt moves the trash upward. The waste drop into the collector. The floor of the trash collector contains small slits to remove water . G. Mobile Application A mobile application has been developed dedicated for the robot. The MIT app inventor software was used to create this mobile app. have the accessibility to move in all four directions, namely- forward, backward, right, left

16. Conclusion Plastic pollution is a very alarming issue There are several prototypes for cleaning floating waste from water bodies. Some of them have been employed commercially as well. Most of the available devices are manned. A huge issue in aquatic robots is safe use of fuels. The use of battery makes our proposed design advantageous and safe, and also opens a scope for using renewable solar energy.
