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.
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.
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.
