PLC Projects
To gain a better understanding of PLC systems, I have designed a few PLC control cabinets in SolidWorks, as well as implemented a PLC system on a potato bag sewing machine. I've also created my own PLC trainer using switches, lights, and a Siemens LOGO PLC.

Robotics Research
During the summer of 2021, I worked in the More-Than-One Robotics Laboratory at UPEI. My research used a wireless armband and a LIDAR sensor to give a robotic wheelchair a "shared autonomy framework". A human operator can operate the wheelchair using hand gestures and arm motions, and the system will automatically take over and avoid obstacles if necessary.During this project I explored areas of robotics such as ROS, gMapping, SLAM, navigation, and hardware design.I published and presented my research in the 2022 19th International Conference on Ubiquitous Robots:
Armband Sensor
(BioX AAL-Band 2.0)
Electric wheelchair modified into mobile robot
Armband being used to control wheelchair
Autonomous safety system taking control to avoid obstacles while staying on human's intended path
Wave Tank Project
For my 3rd year Design Project, I helped convert UPEI's wave tank into a model boat towing tank. The towing tank can be used to test model boats at various speeds to determine which hull designs are most efficient. When the wave tank needs to be used for other projects, the entire track can be rotated out of the way.

Warehouse Layout Project
In 2020 I worked with Russell Ching Ltd to design a layout for their new potato packaging warehouse. Each machine in the existing warehouse was modelled in CAD and laid out on the floor plan of the new building. As a result, the new facility has an improved storage and retrieval system and a more efficient packaging line.

Wedge Cutter Project
For my 2nd year Design Project, I worked with a client to create a spiral wedge cutter using 3D printed metal blades. It was designed to fit into pre-existing potato cutting machines, so the company can easily switch between producing straight-cut fries and spiral wedges. This project earned our team the CSBE Undergraduate Design Project Award.
Drone Robotics Club
In 2020, the UPEI Engineering students created the Drone Robotics Club where we build, program, and test drones to complete missions as part of the NXP HoverGames competition.
Mechatronics Course
Obstacle-Avoiding Robot
Calculator
Servo and DC Motor Control Board
As part of my 3rd year mechatronics course, I used Arduinos to control lights, LED displays, ultrasonic sensors, servos, and DC motors. For my final project, I created a robot with ultrasonic and infrared sensors to avoid both stationary and moving objects.
Weather Balloon Project
In my 1st year engineering design course, we created weather balloon payloads with Raspberry Pi's onboard to take pictures and record weather data from the lower atmosphere. Our weather balloon had a marshmallow positioned in front of the camera to observe the effects of the changing temperatures and pressures.
