In Fall of 2020 I collaborated with a classmate to design a utility multilevel 3 phase Photovoltaic inverter to meet specific design requirements. Multiple switching methods were considered and the output power and distortion were theorized and simulated. See the project details for more information.
sUAS Design for Sensory and Swarm Missions
For this project, I sought to develop a fully autonomous, compact, and lightweight UAV for any intelligent mission. In order to be economical for our student group, the design would have to use commercially available electronics while maintaining stable and efficient flight characteristics. See the details below for how I designed and manufactured a workhorse airframe for researching uses of drone swarms.
Locating Crashed Rockets with Drones
To test applications of autonomous drones, I lead Rocket Locator: a project to locate crashed rockets based on their radio-frequency signature. For this, I constructed an directional antenna array to act as a sensory payload for a heavy-lift octocopter. Find out more about how this system helped accelerate our student group’s software development.
Quad Camp NU: Teaching Students to Build and Fly Drones
Quad Camp NU is a class that I developed to introduce students to drone flight and construction. With the goal of eliminating the entry barrier to UAV and robotics fields, I’ve organized semester-long classes in which students build FPV drones and get to fly them.
Swarm Carrier: Deploying Groups of UAVs From a Carrier Platform
In 2019, I proposed the Swarm Carrier project to research aerial deployment of drones for rapid surveying and search missions. Since then, I’ve lead the development of test payloads and flight missions to further understand how drones can be designed for rapid deployment. Developments include successful drop tests of multiple quadcopters, upcoming tests of a drop and re-integration mission using autonomous landings, and a multi-drop system capable of deploying a group of 6 vehicles.
Heavy-Lift UAV Design
This project describes the construction of a heavy-lift octocopter and its subsequently ongoing iterations for testing a variety of systems. After starting with a commercial airframe, I realized that improvements would have to be made in order to facilitate its use with more advanced payloads and on-board computation. Read on to see how I learned to build and use large multirotors.
Antenna Design and Simulation
This project describes the theoretical evaluation and simulation of multiple antenna topologies that are commonly used with UAVs. After reviewing their theory, I gained a greater understanding of how and why certain antennas were favored for certain applications.
In many of my projects there has been the need to design custom PCBs. I have tried out many different CAD software for multiple different PCB design needs and have learned a lot. Read more to see how my PCB design has improved over the years.
I started flying drones in 2017 and have since been hooked by their ability to capture stunning aerial shots, competitively race, and push the boundaries of robotics research. I’ve built dozens of racing quadcopters and flown a variety of vehicles ranging from wings to commercial airframes.
