ENMT301 RoboCup Robot

Our objective was to design and construct a tank-track robot that could efficiently collect weights and return them to the base within a challenging timeframe.

The chassis of our robot was waterjet cut, providing precise and sturdy construction. We implemented a unique rubber band collection mechanism, allowing the robot to grip and collect weights effectively. To detect the weights, we incorporated a conductive ramp and vertically stacked time of flight sensors that facilitated accurate weight detection.

Returning to the base was made simple yet clever - we designed a homing beacon that latched onto the wall and held a retractable dog leash (yes... a dog leash!). This leash was attached to a joystick atop the robot, which was always pointing towards the home base for easy navigation.

Throughout the project, collaboration played a crucial role in integrating subsystems and coordinating efforts effectively. We established regular team meetings and utilized version control systems to streamline our development process.

We also faced technical challenges, including improving weight detection accuracy and optimizing navigation algorithms. We employed fault tree analysis to identify errors and implement targeted improvements, enhancing precision and capabilities.

By prioritizing essential functionalities and engaging in iterative improvement, we delivered a robust and functional robot within the given timeframe. Our collaborative teamwork and effective communication were instrumental in achieving remarkable results.

Participating in this project refined my technical skills and emphasized the importance of collaborative problem-solving and continuous improvement. It equipped me with valuable knowledge in manufacturing techniques, mechatronics, and teamwork dynamics.

I am excited to apply these skills in future engineering endeavors, where simplicity, efficiency, and collaborative problem-solving are essential.

Custom Rocket Flight Computer

2022

To upskill in embedded software and hardware, a custom flight computer was designed and fabricated. This circuit will be used in my NZRA Level 2 flight attempt.

This flight computer runs off the RP2040 microprocessor. It is fitted with a barometer (BMP390), 6-axis IMU (LSM6DSLTR), three pyro channels, SD card logging, LoRa telemetry communication, and LEDs / buzzers.

Although there were many mistakes made with this board, I consider them extremely valuable. It is through experiencing these issues firsthand that I gained a deeper understanding. Learning through failure often leads to the best learning outcomes.

I have learned so much from this ongoing passion project, and I believe it will significantly contribute to controlling future aerospace projects!

Transcription Search Engine

2020-2022

Contract work for Otago Polytechnic involved developing a search engine for long-form audio. Users could search for topics like "Climate Crisis" and listen to diverse perspectives. Implemented thesaurus searching, wildcard functionality, and an AI model to classify 'interesting' words. Additionally, a side project was undertaken to convert audio into AI-generated images, providing visually engaging representations of podcast discussions.

As part of the side project, extensive audio transcripts were analyzed. Interesting keywords were extracted and generated into a prompt, which served as a basis for creating generative artwork. The image above showcases an automatically generated summary of a podcast which depicts a happy, self-sufficient couple during COVID, symbolizing the concept of being within their own bubble. The sentiment of the podcast was analyzed to determine the appropriate art style. This artwork visually captures the essence of the discussions, offering condensed insights into the key themes and concepts discussed.

The main project involved transcribing and timestamping over 1000 hours of audio, resulting in approximately 10 million words stored in a well-structured database. A user-friendly GUI with multiple functions was created, facilitating seamless exploration of the transcribed data. Throughout my contracting experience, I also honed important skills in writing invoices, meeting deadlines, project planning, and effective client communication.

Level 1 Rocket

2021

My first high-powered rocket built and flown was a 1.42m tall 1/4 scale Patriot kit-set. This project served as a crucial stepping stone in my aerospace journey, demonstrating my hands-on experience and passion for the field.

To capture the exciting moments during the flight, I equipped the rocket with a runcam, enabling onboard footage that can be viewed here:

RoboCup Junior Entries

2016-2019

Ever since a very young age, I have tinkered with mechanical and electronic systems, trying to understand what makes them tick. During intermediate and high school I competed in the RoboCup Junior NZ competition. This was an annual regional and national competition in theatre (open), search and rescue (line following) or robotic football.

2016-2018: First place in theatre/programming at regional and nationals for consecutive years. The project consisted of eight 'MIDI' sequenced robots, with custom fabricated PCB to process the signal and respond with an actuation (drum hit, string pluck etc). Here is a video of that project: https://youtu.be/aKr5ToT69k8

2017-2018: Robotic football-playing robots. Second and third place prizes at a regional and national level.

2019: Line-following search and rescue robot, regional programming prize

Drones and Planes

2016-2023

Since my high school days, I have delved into the fascinating world of drones and planes. As an avid hobbyist aerospace engineer, I have spent countless hours building and flying a variety of aircraft, including 3D printed planes and large-scale multicopters. My passion revolves around pushing the boundaries and discovering the remarkable capabilities of these incredible machines.

Throughout my journey, I have embraced the role of both designer and teacher. I have shared my knowledge and expertise by instructing others on how to build and pilot planes, including my time at Hatch Education and during my studies at university and high school. Using lasercut foamboard and my own designs, I have meticulously crafted and integrated the necessary electronics for these projects.

What truly captivates me is the magic of flight and the unique perspective it offers. By blending my hobbyist approach with aerospace engineering principles, I constantly strive to explore new frontiers and challenge the limits of what drones and planes can accomplish. It is through this journey of exploration that I continue to expand my horizons in the world of aviation.
