Overview

A custom multi-axis motion and test system developed to validate the hardware behind Wing's autonomous delivery drones. The system spans mechanical design, electronics integration, and control software, designed and built with rapid iteration across additive manufacturing, laser cutting, and manual milling.

The Challenge

Drone hardware demands testing under controlled, repeatable conditions that off-the-shelf equipment cannot provide. The system had to deliver precise, reliable motion while remaining manufacturable and quick to iterate, keeping pace with active engineering programs and evolving requirements.

Approach

The mechanical, electrical, and software elements were resolved as one integrated build rather than a set of separate parts, from structural design and motor selection through to the control software driving it.

Motion & Test Systems

At its core is a custom multi-axis motion system built to exercise drone hardware under controlled, repeatable conditions. The mechanical design addresses bearing selection, structural stiffness, motor mounting, weight distribution, and range of motion. Stepper motors, drivers, controllers, and limit-switch and power subsystems are integrated into a functioning platform, with control software in Python and C++ handling data parsing and hardware actuation. The result is a complete system spanning mechanism, electronics, and software, designed and built largely in house.

Mechanical Design

Alongside the larger system sits a steady stream of custom hardware built for engineering teams: fixtures, mounts, assembly aids, and prototype mechanisms. Components are modeled in SolidWorks, Onshape, and Fusion 360, with each design weighed against manufacturability, tolerancing, and speed of iteration.

Process

Understanding the Space Paradigm

The current design process of a new mission is lacking consideration for higher human needs. The process focuses on retrofitting basic human needs in the machine in the stages of Implementation rather than considering all the human needs in the earlier stages of the process

Industry insights

Given the highly specialised nature of the space industry, it was important to engage with experts. I conducted semi-structured interviews with space engineers and space food researchers to collect insights and validate my research.

Project Methodology

I iterated the proposed methodology by using the development of the products as testing grounds to validate it and collect insights for improvements.

Testing through prototyping

I used a mix of prototyping probes and co-design workshops to test my hypothesis for an alternative methodology of creating human artefacts for space.

Testing through co-design workshops

Even though I was working in a vacuum with no real constraints and requirements, the findings helped me develop an iterative process and refine my methodology.
