Welcome to my Portfolio

I am a Bachelor of Mechatronics Engineering with honours graduate who completed his studies at Massey University in Auckland, New Zealand. The projects being showcased helped me improve my engineering skills while also thought me how to work both individually and in teams. This website was created to showcase some of my higher-level projects and researches that I've done during my studies.

Portable, Battery-Powered Under-Table Heater Prototype

Group work

This portable heater was our final year group project, working with a start-up company to design and construct a working prototype of a battery-powered heater. I was nominated as team leader by the group members. My role was to communicate with the stakeholders, ensure the milestones are followed by the team and that the project is on time and to assist and guide my fellow teammates in all development areas such as manufacturing, software development, CAD design etc. In the development process itself my main individual role was to the design and manufacture the battery pack and PCB, and to test other potential components. The final prototype was able to connect to the Wi-Fi network and was remotely controlled by the end user with their smartphones or computers.

Autonomous Forklift Prototype

Group work

The following year-long project required us to design, develop and manufacture a working prototype of an autonomous forklift. The budget for this prototype was set as NZD 500. My role in the group was to assist the part design process, manufacturing and to design and develop the electric system of the product. It was decided to use IR sensors to help navigate the robot by following lines on the ground. The robot was four-wheel drive using 6V, geared DC motors at each wheel. Load lifting was made possible by a high torque stepper motor attached to a lead screw.

Automatic Pneumatic Dispenser

Individual

This project required us to design and build an automatic dispenser to push/remove items from a hopper. For this project tennis balls were used to demonstrate the performance of the system. An infrared sensor was placed in the chamber and when it detected an item the pneumatic arm pushed this item out of the system.

Robot Vision: Sausage Detection

Individual

This program has been created for the Robot Vision paper. The task was to detect the sausages sitting on top of a grill next to an ear of corn and some sliced onions. They were photographed from a top view angle. The program should load in the image, detect only the sausages without the other objects while drawing a rectangle around the sausages to show the detection. It was also required to calculate and display the shortest distance from [0,0] for an imaginary robot arm how it could pick up these sausages. The program was written with the OpenCV library.

Apple Sorter Machine

Individual

The apple sorter machine main task was to sort between red and green apples by distinguishing their colours. Just as for the Pneumatic Dispenser, red and green tennis balls were used to test purposes. The colour detection or object detection was done by using a standard web camera and the OpenCV library for image processing. The program detected the percentage of Red Green or Blue on the image and decided if the colour it detected was green or red and sent the signal to the Server to rotate the sorter left or right depending on the detected colour.

FDM Type 3D Printer for Metal Pellets

Individual

This is my final year individual research paper. The most common additive manufacturing type is FDM printing using filaments. Currently, there are no pellet based FDM printing machines available on the market, which is using the metal injection moulding technique Firstly, a current desktop plastic pellet printer was modified by upgrading the heating and cooling system, implementing a high torque stepper for the extruder and other minor upgrades to make MIM printing possible. The heating system was upgraded with an external controller to support the high temperatures with a high-efficiency water cooling system. To support the larger pressures required in the extruder for printing the metal pellets, a high torque stepper motor was also implemented. When the correct software settings were found, the successful prints were tensile strength tested to measure their constant print quality.

Fatigue Study Of A Hip Joint Prosthetic Implant

Individual

This research was performed to help understand how 10% of Total Hip Arthroplasty (THA) surgeries fail within 9-10 years. We were given to find what the damage to the implant is after 5 million cycles at maximum of 2300N load. Two main standards are used ISO 7206/3 and ISO 7206/4. This is done in solid works simulation. The cement is simulated by using a PMMA material, 75mm diameter cylinder. For the research, two materials (Co-Cr-Mo alloy and 316L Stainless Steel) were tested. The simulations were done in SolidWorks and concluded that the Co-Cr-Mo alloy was a more durable and when using the ISO 7206/4 standard, less stress was found on both the implant and stem.
