    The Monitor
    (2023) Haneen Fozan Rizk Banishamsah; Marwan Naser Dawod Soboh
    In this project, we designed a wearable device consisting of a bracelet that we customized to fit the required functionality. Inside the bracelet, it houses the necessary electronic components and is connected to a sensor that measures heart rate and oxygen levels through the finger. Additionally, when needed, it can also connect to a helmet containing a temperature sensor and a sensor for measuring head tilt angle. This project was modified based on the request of the project committee to make it a more robust hardware project than the one previously proposed, and it was implemented in accordance with the suggestions of the supervising doctor. This device serves a broad spectrum of society, including children, the elderly, travelers, drivers, and patients in general. It collects the user's vital signs through sensors located in the hand, finger, and head and uploads them to a public server using HTTPS for security purposes. It also uploads the user's location from anywhere in the world and sends it to an application that displays this information along with detailed location data. The information is continuously updated automatically every ten seconds (with a margin of error in terms of time and server upload time, taking approximately 10-15 seconds). If these readings fall outside the normal range, for example, if the heart rate is less than 40 or greater than 130, it represents an abnormal reading. The device waits for three consecutive abnormal readings and then sends a text message to the relevant authorities, such as the doctor if the user is a patient, the police if the user is a driver, or emergency services, and in the case of a child user, it notifies the parent, and so on. The message also includes the user or patient's name and their current location. In case there is an issue with data updates or if the device malfunctions due to an accident, for example, it provides the latest readings and the last location from which the readings were taken. As for the sensor measuring the angle of the head, it is used for the driver. If the driver falls asleep while driving or tilts their head down, for example, to use their mobile phone, the sensor detects this and activates an alarm until the head returns to the appropriate driving position. If the driver does not raise their head within twenty seconds, it sends a text message to the relevant authorities.

    Self-driving Car
    (2023) Abdallah Adas; Mohammad Zaied
    The major goal of development the self-driving cars has been driven by the desire to improve road safety, reduce traffic congestion, and provide mobility to those who are unable to drive. Self-driving cars rely heavily on image processing to perceive and understand the driving environment. Image processing involves collecting data from cameras and other sensors installed on the car, and then analyzing that data to extract information about the surroundings. This information is then used by the car to make driving decisions. Pictures will be taken sequentially by a Raspberry Pi camera connected with Raspberry Pi 4, and then these images will be processed by the OpenCV library and machine learning and used Arduino UNO to control the motor driver(H-bridge). The car was able to recognize road lines, drive between these lines, and recognize some traffic signs such as stop signs, green and red traffic lights. Also, the car will be able to detect and overcome obstacles.

    Automated Sample Preparation System
    (2023) Jenan Abualrub; Yaqout Salameh
    Analytical chemistry occupies a crucial role in the medical field for being the deterministic criteria in diagnosis. It primarily relies on performing chemical laboratory tests on patients’ samples , which are widely done manually and vulnerable to errors . In light of these challenges , the development of an automated sample preparation system (ASPS) provides a viable alternative to overcome the flaws of the manual process. The ASPS eliminates the need for manual intervention from the la boratory technician, as a needle would move automatically towards the samples and the reagents based on the selected test. The needle would then sense the substance and precisely dispense the required amount for the test in the reaction cup . Simultaneously , a syringe would help draw ing in and expelling the substances. Throughout the test, the needle is cleaned to prevent any contamination. Additionally , the laboratory technician has the ability to schedule up to 4 tests, which the system would perform seque ntially . The ASPS was developed using Arduino mega, motors, and a sensing circuit built upon capacitance manipulation.

    AutoPizza
    (2023) Shahd Bilal Hamza; Fana Abdul Rahim Yamk
    In response to the increasing demand for convenient and personalized food options, particularly in the case of pizza as a popular fast food choice, our idea is to develop a user-friendly and customizable pizza station. By leveraging technology, our pizza station aims to simplify and automate the pizza-making process, making it faster and more accurate. Whether it's for special events or quick hunger cravings since traditional methods often fall short in terms of speed and customization. Our pizza station presents a straightforward solution to the issue of limited options. Its user-friendly interface allows customers to customize their pizzas effortlessly based on their preferences. Moreover, our station boasts a reasonable size that allows for easy placement in various settings, without occupying excessive space like those found in factories Our pizza station takes a step-by-step approach to pizza-making. The process starts with the use of pre-prepared dough or bread, sourced externally. Once the user specifies their desired pizza options, the pizza goes through different stations tailored to their selections. Finally, it enters the oven and emerges as a delicious, ready-to-eat pie, and notifies the user for it . Our station is carefully designed to minimize waste by efficiently using the necessary ingredients and preserving excess components for future use. This approach not only optimizes the pizza-making process but also aligns with our commitment to environmentally conscious practices. To ensure uninterrupted operations, the machine is equipped with a component tracking system that monitors the availability of ingredients. When a specific component runs out, the system automatically sends a notification to the administrator, prompting them to refill the depleted item. This feature ensures a continuous supply of ingredients for pizza production.

    Claw Machine
    (2023) Sundos Mustafa Saifi; Abdullah Munther Refai
    A claw machine is an enjoyable type of vending machines, it can be found in arcade shops, malls and movie theatres, this machine could be considered as a challenge versus time, in this game a person can control how many minutes he wants to play and he wins the items he gripes in that specified time. This machine gives the player the opportunity to play in one of these options, the first one is using joystick While the second one is from mobile phone application and at last using hand gestures through camera and image processing. This machine is divided into four parts: control, logic control, mechanics and playing area. The logic control consists of Arduino mega as a main controller, five HY-DIV268N-5A motor drivers, ESP8266 for mobile control, orange pi for LTS (single board computer) for hand gestures control, Arduino Uno, SD card module for storing sounds, and power supply for the system. Control part consists of lcd for displaying game instructions and remaining play time, joystick to control the gripper position before gripping item, keypad to specify the time and choose the game control mode (1: joystick, 2: mobile application, 3: hand gestures using camera), RFID for payment and start/catch button. The mechanics part consists of gripper that carried by motor and rope which this motor can be moved through (x, y) plane and the gripper that tied with rope is the z axis, one stepper motors for x movement, two stepper motors for y movement, one stepper for z movement and the last stepper for the gripper, stainless steel rods. The playing area contains the items that the player can grip, speakers for sounds and RGB led strips.
