Cardboard Tricopter Build Plans

Josephine here,

This tricopter frame design is decently ridged, it’s not extremely crash resistant, but it does fine with a few hard landings. This is the first flying revision, so there is plenty of room for design improvements. Improve and share! Available under a creative commons ShareAlike-NonComm-Attrib license.

Cardboard TriCopter

Hot damn!

Von Mises stresses. Von Mises stresses.

My friend Josephine P., taking some inspiration from the cardboard quad, decided to build a paper tri-copter. Using a pretty ingenious tail tilt mount, his Tri-copter comes in at 357g fully loaded. It also costs around 130$ (sans transmitter.)

Cardboard Quadcopter

I finished another frame this afternoon. Now that I’ve made a few of these, the turn around time is getting shorter.

Paper Robots, Part 4

It took a few round, and I went down a few dead ends, but today I finally managed to make a flying paper robot. Originally, I started out with a flying sphere design copied wholesale from the JDM Flying Sphere. Eventually I figured out that I didn’t know the first damn thing about making a flying robot and that it would probably make a bit of sense to try and build one that had been successfully flown by more than one other person working for the Japanese military.

Open Source Parametric CAD

A little while ago I was sitting in a local cafe eating breakfast. I had my calipers, laptop, and a hobby brushless motor controller out in front of me. I carefully measured each dimension, adding bits of geometry between bites of pancake. Eventually, what started out as a simple cube on my screen, started to resemble an accurate model of the object I held in my hand.
