DELFTACOPTER – Hybrid Drone on a Mission

DELFTACOPTER, an electric, long range, transitioning autonomous delta-wing helicopter, is on a mission. What mission? In this case, it’s the 2016 Outback Medical Express challenge and the MAVLab Team at TUDelft has high hopes for their hybrid aircraft.

This year’s Outback Medical Express mission requires a UAV to pick up and bring back a blood sample of an ill-fated person called “Outback Joe” located at an inaccessible roughly known location 30 kilometer away remote location with unknown terrain.

DELFTACOPTER

Powered by PaparazziUAV, the DELFTACOPTER is also equipped with state of the art on-board stereoscopic wide field of view computer vision.

Drones vs. Retro-gaming: fly with a Game Boy Classic

Some time ago, I found my old Game Boy at my parents’ house. So the first thing that came to my mind was: can I fly a drone with this ? (and also where is my Mario Bros cartridge).

So I spend some time searching the web to see if I could find some idea to solve my problem. And if it seems that piloting unmanned aircraft with a Game Boy is not so common, you can find everything you need to program it!

But you can’t expect to go directly to an old custom serial com port to a wifi-based drone without some intermediate steps:

gb-ardrone2-wiringFinally, the Game Boy is just sending the bitmask corresponding to the buttons being pressed (with an Arduino and a FTDI to convert Game Link signals to USB), and a small program on the ground station converts this into actual commands for the drone (an ARDrone2 from Parrot with an extra GPS in my case).

The result is here:

Introduction to the G0 GPS

Dear Paparazzians,

I made a new video describing the details of the G0 Paparazzi UAV GPS receiver module. In the video I go through and describe the several design decisions we made to ensure high Signal to Noise Ratio, good multi path GPS signal rejection and overall reliability of the GPS for use in airborne robotics applications.

I hope this video is helpful. If you think so too please let me know in the YouTube comments. If you enjoyed the video make sure to like it on YouTube and subscribe to the channel.

Check out the G0 paparazzi wiki page for more information about the GPS.

G0 is now available for purchase in the 1BitSquared store together with the Elle0 autopilot. It is available in both of our stores; the US Store and the German Store. So if you live in the European union, you can now buy Elle for your next UAV project without having to worry about customs and shipping time. 🙂

Cheers, and successful flights,
Esden and the 1BitSquared team

Introduction to the Elle0 Autopilot

Dear Paparazzians,

I made a new video describing the details of the Elle0 Paparazzi UAV autopilot. Elle0 is now available for purchase in the 1BitSquared store together with the G0 companion GPS receiver. In the video I go through and describe every IO pin as well as some of the design differences to the Lisa/MX Autopilot. Additionally, I describe how you can add a battery voltage monitor to your Elle0 using a voltage divider circuit.

I hope this video is helpful. If you think so too please let me know in the YouTube comments. I am planning to make many more videos describing different aspects of Paparazzi UAV, not only hardware but also flight videos and Paparazzi software tutorials and tips. If you think it will be useful for you make sure to subscribe and tell me in the comments what you would like to see.

Also, check out the Elle0 paparazzi wiki page for more information about the autopilot itself and diagrams of the system. Additionally to the Elle0 and G0 boards we have also released a matching R0 radio board and UU0 UART to USB adapter boards. We will be making videos describing more parts of the modular system we are working on soon. Whereas the Elle0 and G0 are already in stock, the R0 & UU0 are available for Pre-Order in our US store.

Cheers, and successful flights,
Esden and the 1BitSquared team

Multi MAV Autonomous Flight

Rich Burton of Hooperfly made a video showcasing the flexibility and accuracy of the PaparazziUAV system running on the
1BitSquared Lisa/MX autopilot.

Using Paparazzi’s flight plan software to dictate a pattern of waypoints for three of his TeensyFly MAV’s to take off autonomously, hover, fly a rectangular pattern, hover and land. All the flight plan blocks are triggered in unison with a custom papget xml config file. The unison nature of their flight is quite beautiful to behold.

And a behind the scenes clip of a flying robot getting a little help from a friend.  🙂
