Projects
The following is a selection of the projects in which I have been involved or have personally initiated.
Gamified Occupational Augmented Therapy - FYDP
September 2023 to April 2024
The project aimed to enhance rehabilitation adherence by gamifying exercises using Virtual Reality (VR) technologies, drawing inspiration from successful applications in pediatric and stroke rehabilitation. Leveraging VR's immersive capabilities, the project sought to make rehab exercises engaging and effective. As the project manager, I led the team, ensuring tasks were delegated and deadlines met while managing project finances. My vision guided the project's implementation, and as the Mechanical Lead, I designed and prepared all mechanical components for 3D printing. I also maintained our project's online presence. Additionally, I oversaw the assembly of the final prototype, demonstrating my comprehensive involvement in the project's execution.







Ball and Beam Control Design
September 2023 to November 2023
The lab focuses on a classical control experiment aiming to position a ball on a beam by adjusting its inclination. The motor voltage serves as input, while both ball position and motor gear angle are measurable outputs in this experimental setup. To attain stable control of this inherently unstable nonlinear system, a double nested control feedback system was devised. Utilizing the Nyquist stability criterion, MATLAB and Simulink facilitated calculations and simulations. Initially, the motor system's plant was identified by observing its response under a proportional feedback loop. Subsequently, a first-order controller was tailored to meet inner loop specifications, governing the motor gear angle. A second-order controller was then devised to fulfill outer loop requirements, regulating the ball's position.
Magnetic Wall Climbing Robot
January 2023 to March 2023
Our project aimed to create a robot capable of conducting efficient Search and Rescue missions, emphasizing quick setup and independent operation. The task involved traversing between two bases separated by a wall, staying within the defined search area. Our solution involved designing a robot equipped with specialized features for this purpose. To surmount the wall safely, we incorporated two powerful magnets: one for wall engagement and another for stability. Navigation toward the base was achieved through the implementation of two ultrasonic sensors, facilitating accurate location detection. This solution ensured the robot could autonomously navigate, overcome obstacles, and successfully complete the Search and Rescue operation within the designated area.








Tourniquet
March 2022 to April 2022
The goal of this project is to design and develop a tourniquet that is capable of achieving limb occlusion pressure, while also being cost-effective and easily manufactured in a short period of time, as it will be donated. The tourniquet consists of two parts: the cleat and the band. The first step is to select the appropriate material for the tourniquet based on factors such as price, strength, elongation, and friction. Then, the geometry and equipment needed for cutting the material must be determined. Next, the cleat must be designed based on the geometry and properties of the band to hold it in place and achieve limb occlusion pressure.

Universal Handlebar Phone Mount
July 2021 to August 2021
This is a highly adjustable phone mount utilizing a ball and socket joint that is compatible with any type of filament, requiring minimal support material, and designed to be easily printed on any FDM 3D printer. This mount is designed to accommodate vertically mounted phones with a width ranging from 5.72 cm (2 ¼ inches) to 10.8 cm (4 ¼ inches), including the smallest phones such as iPhone 13 mini and the largest phones such as Samsung Galaxy S22 Ultra, even with a case. The mount can be attached to a cylindrical bar with a diameter of 0.8 inches to 1 ¼ inches, commonly found on motorcycles, snowmobiles, jet skis, ATVs, etc. by using two #6 or #8 bolts and nuts.

Maze Solver
October 2019 to December 2019
The objective of this project was to design and develop a robot capable of navigating through various mazes, determining if a solution exists and if so, identifying the most efficient path to the solution. The robot is equipped with the ability to self-calibrate, locate the start and end of the maze, and not only find a solution but also eliminate any dead ends to determine the shortest path. In the event that no solution is found, the robot will recognize this and display an appropriate message. This project encompasses both the mechanical design and implementation of various components, such as the chassis, motor drive and sensor attachment, as well as the software design and implementation using RobotC and C++.

Young’s Modulus Experiment
March 2019 to April 2019
The purpose of this report is to evaluate the Young's modulus of a wooden meter stick by analyzing the relationship between the deflection of a loaded beam and its overhang length using Excel. The Young's modulus will be calculated by using the formula E=(4mgL^3)/(Dwt^3) where E is the Young's modulus in Newtons per square meter, m is the hanging mass in kilograms, g is the acceleration due to gravity in meters per second squared, L and D are the deflection and overhang length of the meter stick respectively in meters, and w and t are the width and thickness of the meter stick respectively in meters. To know more about the process and data refer to the report below.


World Population Trend
October 2017 to January 2018
Overpopulation has been a significant concern throughout the past century, leading to numerous challenges such as resource scarcity, hunger, thirst, mass migration, diseases, pollution, and climate change. This research paper aims to study the trend of the world's population from the 1950s to 2015, by utilizing a logistic function derived from three different methods to determine the accuracy of the model.

Catalyst Effects on Activation Energy
October 2017 to January 2018
Catalysts play a crucial role in chemistry as they accelerate reactions without being consumed in the process. This research paper aims to investigate the correlation between the mass of a catalyst and the rate of reaction, as well as its activation energy in the decomposition of hydrogen peroxide using the Arrhenius relationship. The experiment was conducted using PASCO laboratory equipment. Data was collected using PASCO Capstone and subsequently analyzed using Excel.

Energy conservation coefficient
October 2017 to January 2018
The objective of this research paper is to measure the coefficient of energy conservation of a ping-pong ball when dropped, by utilizing the principle of energy conservation. The experiments were recorded using video and the data was analyzed using Logger Pro, followed by processing the data in Excel to arrive at conclusions. To gain a deeper understanding of the research and its findings, kindly refer to the full report below.
Autonomous Rescue Line Robot
January 2014 to March 2014
Designed and programmed an autonomous robot for the RoboCup Junior Rescue League competition. The competition entailed navigating a course following a black line, overcoming obstacles, and rescuing "victims" using the robot. We used Altium Designer for designing the PCBs and CodeVisionAVR for developing the algorithm. Unfortunately, due to my immigration from Iran to Canada, I was unable to see the project through. You can find the competition environment, the final PCBs, and the schematic drawings in the provided materials on the right.







Autonomous Firefighting Robot
February 2013 to April 2013
Designed and built an autonomous firefighting robot using readily available electrical and mechanical parts, to compete in a school-wide competition. The objective of the competition was to detect and put out the fire as fast as possible. I learned the basics of circuits, soldering, and microprocessor programming at an early age.
