Hello my name is

George Partridge

I'm a second-year Mechanical Engineering student at Georgia Tech. My interests lie in robotics, engineering, and rapid prototyping.

I'm working on a four-wheel differential swerve robot, and carrying on with the speed drone's GPS autonomy when I have time. Currently reading Protocols by Andrew Huberman. Reach out if you're working on something in this space.

Personal Project CFD 325 km/h GPS peak

Quadcopter Speed Drone

A 3D-printed quadcopter built for top speed from stock 5" parts, with GPS onboard for future autonomous flight. I designed the airframe in SolidWorks around the electronics and camera, then simulated airflow in OpenFOAM from −4° to 13° and 10 to 100 m/s to compare four fuselage shapes. I soldered all the electronics 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

4-Wheel Differential Swerve Robot

A four-wheel robot where every wheel sits in a differential swerve module: two N20 motors both steer and drive each wheel, so the robot can move in any direction while rotating. I modelled it in Fusion 360, 3D-printed every structural part and ran FEA on the gears. A Raspberry Pi 5 handles LiDAR mapping and path planning, while an ESP32 on a custom PCB runs the motors.

  • 4 modules, 8 motors with unlimited steering, since no wires turn with the wheel
  • 12 MPa peak gear stress at motor stall, against about 50 MPa for PLA
  • 88 × 33 mm two-layer KiCad PCB replaces two hand-wired boards, with 0 design-rule errors
  • Next: module testing, closed-loop control and LiDAR mapping
