An Absurdly Small Tri-copter

The team behind the Femtoduino – an extraordinarily small repackaging of the Arduino – sent in a few videos from YouTuber [phineasIV], a.k.a. [Eric] that shows one of the smallest multicopters we’ve ever seen.

Because this isn’t a traditional quad or hexcopter, the control system is a little weird. Two of the motors and props are fixed along the vertical axis, while the rear prop is connected to a small servo to rotate from side to side. Still, the electronics are fairly standard for any multi rotor vehicle – a triple-axis gyro provides the stability of the vehicle coupled with MultiWii, while an amazingly small servo receiver, Bluetooth module,, Femtoduino, and a trio of brushless ESCs tie everything together.

The end result is a tri-copter that weighs about the same as the Crazyflie Nano Quadcopter, but is just a bit smaller. As impressive as it is on video (seen below), we’d love to see this tiny robotic hummingbird in person.

  1. Damn, it amazes me how far tech has come since I was in highschool. It seems like there is no limit to what can be done with a few dollars, and internet connection and a list of electronics supplier websites.

  2. Change battery for supercap, make a charging station, come up with a way for the copter to hover and charge -> ACTUAL humming bird tricopter…
    Or maybe even add a few more copters and have the most awesome (and most annoying :P) home decoration :D

  3. I own an Armattan quad that is plain awesome, fast, you can crash it a ton, and so forth.
    My vision is poor and I want a smaller quad so I can fly closer to myself, plus not worry about hacking someone with it. A little tri copter could be the ticket :)
