360 degree stereo vision and obstacle avoidance on a Crazyflie nano quadrotor

(More info and full post here)

I've been experimenting with putting 360 degree vision, including stereo vision, onto a Crazyflie nano quadrotor to assist with flight in near-Earth and indoor environments. Four stereo boards, each holding two image sensor chips and lenses, together see in all directions except up and down. We developed the image sensor chips…

Successful flight test of gas+electric VTOL UAV: HYBRiX

This is the crazy project that kept us busy lately at Quaternium: a hybrid electric+gas multirotor with range extender, inspired by Hybrid cars, such as BMWi3.

Our goal is to overcome the endurance limitations of an electric multicopter, while keeping the multirotor platform we are so enthusiastic about. This VTOL UAV has 2.5 hr estimated flight time with payload, and around 4 hours endurance…

An efficient VTOL fixed wing/rotary wing that does not need a rotor head.

Hello all,

I am working on a VTOL concept and thought I would post it here.  I hope to get as much feedback as possible from anyone who has any.  The depicted airframe is the simplest embodiment that would be capable of both rotary and fixed wing flight.  Alternative versions could look very…

A few stats on crowdfunded drone projects that I backed

It bears repeating: Drones Are Hard. Above are some stats on the projects I've backed. I don't regret funding any of them, since I like encouraging these sorts of projects and I learn a lot from their updates. When a crowdfunding project I've backed actually shows up, I'm amazed (I…

Autonomous RiverBot(TM) Goes 15 Meters Deep

From Hack a Day by Al Williams

If you want to make a submersible robot (or, really, any robot) you can either design it for a specific mission, or you can try to make it general purpose. The researchers at the Cura Oceanus Foundation opted for the latter approach with…
