Hello my name is

George Partridge

I'm a second-year Mechanical Engineering student at Georgia Tech. I'm most interested in robotics and rapid prototyping.

Updated October 2026

Building a four-wheel differential swerve robot. When I have time, I go back to the speed drone and work on GPS autonomy.

4-Wheel Differential Swerve Robot

Each of the four wheels steers and drives on its own, so the robot can move in any direction while it turns. The chassis is fully 3D printed and carries custom electronics and a LiDAR for mapping. I'm building it now, and I sized every part from hand calculations before printing.

Quadcopter Speed Drone

A 3D-printed quadcopter built from stock 5" parts to go as fast as possible. It carries GPS so I can add autonomous flight later. I designed the airframe in SolidWorks around the electronics and camera, then compared four fuselage shapes in OpenFOAM at angles from −4° to 13° and speeds from 10 to 100 m/s. I soldered all the electronics myself and tuned it in ArduPilot.

  • 325 km/h GPS peak on the third flight, unverified (172 km/h on the maiden, at 48% throttle)
  • 880 g printed in PLA
  • Peak L/D of 9.1 at 5°, and passively pitch-stable
Coming soon

Quasi Direct Drive Actuator

A new project. The write-up, photos and build log will go here once it's underway.

Light building

Lamps and fixtures I print on my Bambu A1 between bigger projects, plus a hanging planter. I modelled the mini lamp in Fusion as three parts you can download below, a base, a clicker and a shade.
