Legged Helicopter Landing Gear
One of my biggest projects to date is a legged landing gear that allows helicopters to land on uneven terrain with large touchdown velocity. For a quick overview, please see the following video. Inspiration Traditional helicopter landing gears generally consist of two tubular skids, or three wheels for larger helicopters. These designs require a very…

Relationships Between Current, Angular Velocity, and Torque in Position-Controlled Servos
TL;DR I did some experimentation on whether or not it is possible to estimate the shaft torque on a cheap, position-controlled hobby servo using current and angular velocity. A paper documenting the findings along with the complete data is available is available on GitHub (direct link to paper: paper.pdf). Background At Darien High School, I’m part of…
