    Plastic classification with infrared radiation
    (2023) Shahd Ismail; Hala HajAli
    Most of the things around us contain plastic in their composition, which makes plastic one of the most widespread materials on earth, and as a result of its short life, this makes the recycling process necessary and important. The recycling process requires a highly accurate sorting process, and it is not logical that the separation process is done manually, which led to the development of automatic methods of separation. This project focuses on the development of an automated system that utilizes near-infrared reflectance spectroscopy to identify and separate different types of plastic. The system employs the principles of near-infrared radiation to analyze the reflective properties of plastic samples.using a conveyer belt, the plastic piece is placed on it and separated based on a reading that is taken and sorted into containers using an air pump. 3

    Clothes Printing Machine
    (2024) Tasneem Adnan Khalil; Asma Jehad Hamideh
    The fashion industry’s demand for personalized and custom clothing has grown exponentially. Our hardware graduation project presents an innovative system that combines color mixing technology with screen printing to enable customized clothing design. Also, screen printing takes a lot of physical effort when done manually. By automating the screen-printing part, we save time and a lot of effort in producing personalized clothes. Our goal is to design a hardware system capable of accurately mixing colors and use them in the screen-printing process for fabric customization. It utilizes a 2 X,Y CNC’s with limit switches to handle clothes and printing on the frames. and a Spur gears with stepper motor and reed switch for choosing the design. A color mixing unit using peristaltic pumps, a color sensor and a motor for mixing. Users will get to choose between 6 colors and 3 designs through either an LCD with a keypad. Or a mobile application connected to the machine through Bluetooth. 5

    Tennis Ball Collector
    (2023) Asala Tibi; Hala Barqawi
    Tennis, a widely popular game, is a racket sport that takes place on a rectangular and flat surface court. During tennis training sessions, manually collecting the balls can be a laborious task , and the process of retrieving the balls manually can be time-consuming and physically demanding. This project aims to address the laborious task of manually collecting tennis balls during training sessions by developing an autonomous robotic tennis ball collector. The objective is to design a robot capable of navigating the tennis court, detecting tennis balls using image processing techniques, and autonomously collecting them, thereby allowing players to rest instead of manually retrieving the balls. The robot features four independentlyactuated wheels. A gate mechanism is employed to push the tennis balls into a basket mounted on the robot. A camera mounted on the robot captures images, which are processed using OpenCV libraries on a Raspberry Pi to detect tennis balls through an edge detection algorithm. This project presents an effective solution for automating the collection of tennis balls during training sessions, providing convenience and relief to players from the manual collection task.

    Grass Cutting Robot
    (2023) Haneen Yaqoub; Rana Mara’beh
    With the increase in green spaces in the world, people need to take care of them, but we do not deny that they require a lot of time and effort, which sometimes a person does not have the space for. From this standpoint, we thought to find a solution that could help in the process of caring for plants and save time and effort for humans, so we started our idea by working on a robot that cuts green grass when it reaches a certain length in the garden and with work on the idea of making its movement logical and suitable for the work that will It is done by this robot. For the movement, it begins with the ability of this robot to cover all the existing space in addition to its ability to move away from the obstacles that appear in front of it. In addition,to make it easier for the user, two modes of movement are provided, either automatically or by the user controlling his movement. In addition To facilitate the movement process, this robot cuts the grass only when it has reached a certain length, and this saves energy on the robot instead of constantly cutting, and to take care of the garden in all respects, we have added the feature of watering the crops when a low level of moisture is reached in the soil. This is done wirelessly by sending a notification to the robot from the soil sensor, then the robot pumps water to increase the moisture level in the soil.

    Automated Car Washer
    (2024) Suhaib Darawshi; Khaled Jeetan
    This graduation project presents the design and development of an Automated Car Wash Machine, aimed at providing efficient car cleaning services. The system combines automation, cost analysis, and remote monitoring to create an innovative solution for car owners and businesses alike. The main components of this project include a conveyor belt system that guides the car through various stages of the washing process. The car is first subjected to a water splash to remove loose dirt , followed by the application of soap for a thorough cleaning, and then another water splash to clean off the soap . The automated process ensures consistent and high-quality results, reducing the need for manual washing. The project contains cost analysis component. By measuring the amount of water and soap used during each car wash cycle, the system calculates the cost of the service. This helps car wash businesses optimize their resource utilization ,to make their analysis for the profits. The system also includes remote monitoring capabilities. An integrated camera system captures real-time footage of the car wash process, which can be accessed via a mobile application. This feature enables car wash administrators to monitor operations remotely, ensuring smooth functioning and addressing any issues promptly. The system will contain sensors to realize the position of the car on the belt , these sensors should verify that the process walked correctly , in case any of the three processes didn’t happen correctly , or the car was stuck on the belt .
