Hello everyone!

I have posted several times information about our 3-axis gyro-stabilized gimbals, but this time we decided to release a short video with close up review and actual footage from the gimbal itself. USG-301 is one of the most popular products from our line of gimbals. It features state of the art Full HD Sony sensor with 30x optical zoom. Comparing to previous versions of our gimbal we have greatly improved gyro-stabilization, which made the image even better looking and also added onboard video recording and ability to take still images on SD card. Those two features were asked many times by our clients and partners who are involved in drone inspections, agriculture and other industrial drone applications. In addition, we have tested the gimbal on other than DJI multirotor drones. Great example is our work with UAV America's Eagle XF drone, which you can see here: https://www.youtube.com/watch?v=TxpbNVNCqS4 We have created custom mounting plate, so the gimbal perfectly fits the airframe. 

Right now we are working with other drone manufacturers to integrate our payloads and very soon we will show the results of our work. With the price much less than 7k and taking in account all advantages of our USG-301 we think that we have a great opportunity to work with many drone manufacturers around the world. If you are a drone manufacturer or using drones for your business and looking for a reliable and affordable camera payload feel free to reach us to discuss how we can work together.

Walkera Vitus folding drone game console

Walkera Vitus is a folding quadcopter, a game console, with a fully equipped GPS system, a mini stabilized 3-axis gimbal and a 4k HD camera.  We flew it at our golf course for our first flight.  The functions include Follow Me Active Track, Waypoints and Gesture movements.  The game console allows you to play Mix Reality games, considered the next generation of drones with augmented reality that allows you to plays games while you fly.  This version comes in three game modes: Racing, Combat and Collection.  Hands shaking, anxious, I think overall not bad for our first flight footage.

  • greatly improved UAVCAN support, with parameters now in CAN_ parameter space
  • support for prop-hang on 3D aircraft
  • improved quadplane PID logging
  • smoother takeoffs for quadplanes
  • logging of side-slip and angle-of-attack estimates
  • added AETR, pre-mixer logging
  • automatic thermalling support

The documentation23 has had a major update as well, with new setup guides33 for popular aircraft types, including 4-channel planes, elevon planes, vtail and flaperon setups, tailsitters, quadplanes and tilt-rotors.

Many thanks to everyone who contributed to this release - it has been a long time coming, but I think it was worth the wait. The dev team hopes you enjoy flying it as much as we have enjoyed working on it!

Happy flying!

Thanks Tridge and ArduPilot development team!

Drone Landing Autonomously on Walls

Hi everyone, here is a video of a new perching drone that we developped, called S-MAD (Sherbrooke's Multimodal Autonomous Drone).

It's the first fixed-wing drone that autonomously perches and takes off from vertical surfaces, both indoors and outdoors. This kind of ability enables small UAVs to perform extended missions, offering new types of applications. Ultimately, such bird-inspired platforms could be used for long duration surveillance, energy harvesting, inspection of structures or reconfigurable sensor networks.

We also have a paper on this with more detail, available on Springer.

Cheers,

Dino

Introducing OpenSolo!

3689719471?profile=original

Big news! Reposting from the 3DR blog. Also see the ArduPilot Team announcement here. 

When we launched Solo back in 2015, one of its selling points was that it was based on the open source ArduPilot software, the project that Jordi Munoz and I launched as a side-project way back in 2007 and then grew beyond our imagination in the able hands of the community.  The point of Solo was to package up this open stack in a polished, easy-to-use consumer product (like the DJI Phantom), treating the ArduPilot stack as an “open core” and extending its functionality with proprietary features much as companies do with Linux-based devices.

This worked very well as a product (Solo had some really innovative features, some of which are still unequaled) but less well as a business (we couldn’t make it cheaply enough to keep up with the rapid price declines in the consumer market, so we stopped making them at the end of 2015).  Now, two years later, 3DR has shifted its focus to the commercial market that exploded after the FAA launched its Part 107 commercial operator licensing program last year. But there are lots of Solos still out there, with great untapped potential — it’s just not our core business anymore.

So what to do? Open source the rest of it! We’ve heard loud and clear that the community wants a tried-and-true Ardupilot platform that can be extended without limit. The Ardupilot team has already embraced Solo and ported the latest flight code to it. But the custom 3DR WiFi control, telemetry, and video streaming technology, the “Artoo” controller and the “Shot Manager” mission control stack that runs on the onboard Linux processor were not open source, so the full potential of the drone remained locked.

No more. I’m delighted to announce that we’re now open sourcing almost all of the remaining code, including the SoloLink wireless stack, ShotManager, the high-level onboard mission scripting layer that gave Solo all of its “smart shots”, and a range of other packages include the code for the controller and the build tools.

The code has now been released in a new OpenSolo organization on Github, licenced under the permissive Apache 2.0 licence.

More details about what’s been released here:

solo-builder – scripts for configuring a virtual machine to build the Solo software

meta-3dr – the build recipes that assemble the complete Linux system for the Solo and Controller i.MX6 processors.

shotmanager – implementation of Solo’s Smart Shots.

sololink – 3DR software that runs on the i.MX6 processors, implementing things like video streaming, control, telemetry, pairing, logging, etc.

artoo – firmware for the STM32 microcontroller in the controller responsible for the inputs and screen.

solo-gimbal (coming soon) – firmware for the microcontrollers in the Solo Gimbal

mRo mid 2017 updates

3689719326?profile=original

Hi there! It has been almost a year since we re-opened our DIY store and I can report a lot is going on inside mRo as I write this. Our mission to be the best drone component manufacturer in the USA (World?) is no easy task!
In January, our sales increased more than we have anticipated, rather than compromise on our mission, I decided to stay quiet and not promote anything until we had stabilized our production line, sadly that was not possible (duh!). I was afraid that if we continued to grow that fast, we would start having problems and... I was right, we did. We have been able to iron out all those issues. Luckily, one of our first steps was a proper ERP/MRP system, which helped us keep production details very accurate and we added several new automated inspection machines.
I would like to thanks all our customers who supported us and gave us the chance to correct all our initial mistakes. We will not let you down, we never did!
I also wanted to share my gratitude to all mRo staff who have done unbelievable things to keep everything running smoothly and help implement all the foundations needed in our quest to be a World Class, NASA grade company.


Important news...

I'm glad to announce the merging of AUAV and mRo.
After working together with Phillip Kocmoud & Nick Arsov, we realized we had numerous "parallel" projects, so it didn't make sense to compete and work double. On the other side mRo didn't have the bandwidth to layout a new autopilot (at the moment), and AUAV already had cool autopilots that when combined with mRo manufacturing capabilities in California will allow us both to have such fantastic systems available sooner and with constant high quality supply (& support). That means more and better DIY options for everyone. ;-) AUAV continues to focus on research and development as well as outsourced custom flight controller designs, if your hobby needs become more serious. This can cut a design solution time-frame to just a fraction.
With this merging, mRo will become one of the most experienced DIY Drone companies in the world (Sounds cool huh?).
Putting under our belts the experience of creating/debugging products like Ardupilot 1, APM1, APM2.5, ArduIMU 1&2, PX4 Autopilot, PixHawk 1, The Solo Cube, Solo Link, AUAV3 (UAV Dev Board. Hi Bill we love you and your DCM!), PixRacer, AUAV X2, X2, X2.1, AUAV X3, AUAV X4, Pixhawk Pro (The FMUv4 Standard). Among other innovative products (at their time) like the MinimOSD, optimized PPM encoder, uBlox GPS to the masses, differential I2C and the first budget power module with hall sensor. Just to mention a few. =P


Clarification: In most of those projects we were involved 100% and when I say we, I mean AUAV team and ex-3DR employees that now some of them work for mRo, not just designing, but also in the complex production lines, from ex-Tijuana factory and China (when fabricated Solo).

3689719295?profile=original

[Picture for sizing reference, plus a few Easter eggs, except for PH2 or PixHawk Mini, we've made everything else]


Here comes the "meat," our new products for you:

-uGPS, uBlox SAM8. The tiniest GPS+Glonass GPS out there, it also has a built-in magnetometer. uBlox entirely designed the antenna+RF and we trust them with our lives! Well, the life of our Drones.
-ACSP7 is ready! First micro (17mm x 17mm) power module with hall sensor, no more invasive, noisy readings (especially below 5-8 Amperes).
-Next generation AirSpeed sensor. MS5525, Temperature compensated. Wuju!
-FTDI to JST-GH. Easily attach your ports or GPSs for debugging. 
-Military grade Shielding for your GPS.

-Don't forget our list of Fantastic Cables and where to find them! 

Coming soon:
-X2.1 Rev B. Which is a redux version of the robust and popular PixHawk1, but with newer/better sensors, and some standard JST-GH connections and incredibly flexible when building your drone. We are not adopting any known names like PixHawk 4000 or Ardupilot 7000; sadly there are a lot of politics and interests everywhere right now that can potentially delay our products. We just want to focus on designing good electronics and make them available to you as soon as possible, so you can get the work done or get fun.

3689719410?profile=original

Note: Pins can be either right angle, straight or both. 

The X2.1 has a few advantages, with ArduPilot 3.5, dampening is no longer required, which reduces price and removes failing points. I can tell you a lot of the issues I saw on the Cube used on Solo (We have the official Solo repair center in the same roof, Current UAS). Is not that bad, you can easily fix most of those issues, for example, a common problem the cube has is the foam getting stuck, with X2.1 you don't have to worry about this.
Besides, the dampening was calibrated just for SOLO so that it won't be as useful in other vehicles with a substantial difference in vibrating frequencies. We proposed sorting the cubes in different colors, so each had a different damping frequency range. For this and other reasons, as 3DR, we decided not to make our own version of the Cube and rather give an actual DIY attribute to X2.1.

So, X2.1 is the most DIY friendly and capable Autopilot we have made so far. You can adapt and solder your custom shields with ease in just minutes, or you can get fancy and layout your PCB to populate all you want on board, no complex, difficult to align connectors required. If you are not interested in that, you can just use standard 0.1" pins/cables to plug into your system. Every pin, almost every signal is the same as PixHawk 1, expect an excellent integration with your "actual" drone.


3689719425?profile=original

-Lastly but not least, our Solo Link, now mRo Link, based on the i.MX6.
Believe it or not, we are still working on this project as I mentioned here. Now that 3DR has officially open sourced the SOLO; we feel more comfortable than ever to put full weight on this project. We already have everything working; we just need to remove what is not required and make it "smaller." Check our picture up here with all of the boards. You might see it. 
We are bringing a top engineer from the other side of the world to dedicate to this project during August 2017 fully. So expect more news early September 2017. BTW we know that somebody else already released something (Fox), which we fully support and that is precisely what we love about open source. We hope to work together in the future.

Enjoy my wife's lazy cat:

The first FlightZoomer Version 3 app has been released!

Anybody, who has access to a Windows 10 computer, is invited to visit the MS store and install "FlightZoomer Cockpit 3 - Simulation Edition" for free!

The simulation edition is perfect to try out, evaluate or even train FlightZoomer at no cost and without needing any additional hardware!

The walkthrough video gives you a first impression about the app and shows all steps to finish a simple flight.

For more details about FlightZoomer Version 3 please refer to my earlier blogposts:

What is FlightZoomer?

FlightZoomer is a groundstation coupled with a companion computer (in essence a distributed companion computer), that runs on-top of ArduPilot and offers unparalleled navigation and autoflight features for drones and RC aircraft. The system closely recreates the look&feel and features of a real Boeing 787 cockpit. If you want to actually fly you need the regular FlightZoomer Cockpit 3 app (to be released in Q3 2017). Additionally you need a smartphone, that runs the app FlightZoomer Companion 3, which will be attached to the aircraft or drone.

Custom FPV Rover

We had the opportunity to build a rover for a demonstration that Northrop Grumman just had. Thought I would share it.
6smMPbv.jpg?width=750
The basic idea was to help address the bad wrap drones get from the news. NGC has been using something they call a Global Innovation Summit to demonstrate drones capabilities that helps humanity. This year was a beta test for a team of drones that will fight simulated fires that represent disasters around the globe. Bellow is a picture of the field. They marked out the world with boxes that would deploy simulated fires.

3689720516?profile=original
They had 5 teams: Fixed wing Eye in the Sky that loitered waiting to identify fires and their location, this info was relayed back to command that dispatched either a fixed wing fire bomber(fight Forrest fires), multi rotors supply (drops supplies into a disaster area), or a heavy lift multi rotor that delivered a rover(fight urban fires). Everything was completed through FPV on board each vehicle, all teams and pilots were blind to the actual field. Every team was asked to perform tasks manually, semi-auto and fully auto.


Check it out, all 100% designed and built in house at our high school. I am new to this so I apologize for lack of detail just ask and I will do my best to answer.

Hello,

Here is a DIY design & build of a small  (300 class, 9" props) compact foldable  quadcopter you can take in a backpack, weighing less than a kilogram (including a Drotek RTK GPS, CUAV V3 pro pixhawk autopilot , telemetry radio)

It can fly a good 30 minutes with a 3-axis Gopro type gimbal (subject of part2). The frame is foldable (with and without props attached).

It flies of course with Arducopter firmware V3.4.6.

For those inetrested , I had made a previous review of the CUAV V3 pro (Pixhack) autopilot :

E-flite Convergence Vtol test

E-flite-convergence-vtol-in-box.jpg

I definitely recommend this excellent and super fun aircraft E-flite Convergence Vtol. Why? go ahead, after reading this E-flite convergence vtol review you will know the reason.

Unboxing

There are one boboy convergence vtol BNF, two pair propellers, two vertical fins and one user manual in the foam box.  The quality of the E-flite convergence vtol feels pretty good as is expected from Horizon Hobby.

Assembly

Install the vertical fins: Install the vertical fins on the fuselage using two screws per side.

Install  propellers:The main propellers are labelled near the hub with an “R” and an “L” to show on which side they should be installed.

Install battery:Install the fully charged battery in the battery compartment. Secure using the hook and loop strap. Connect the battery to the flight controller. Refer to the Center of Gravity section to ensure the model balances at the
recommended CG.

E-flite-convergence-vtol-install-battery-768x460.jpg

Install FPV system

Items required for FPV system installation, there are camera,video transmiter,antenna and video monitor with headset or goggles.

FPV-System-Installation.jpg?width=350

Flight test

For your first flights with the recommended battery pack, set your transmitter timer or a stopwatch to 6 minutes.

To transition to airplane flight from multirotor flight, change the flight attitude switch on your transmitter to the airplane flight position. The throttle will increase slightly and the motor nacelles will rotate forward in three stages to the airplane flight position.

To transition to multirotor flight from airplane flight, reduce the airspeed, change the flight attitude switch on your transmitter to the multirotor flight position and stability mode for landing.

With enough satellite signals, single frequency RTK receiver works well under open sky environment. Of available ones on the market, we have yet to see one that works well in environment with surrounding trees and buildings. The above video shows a new level of performance with our soon to be released update firmware enabling to work under such condition.

The recorded NMEA is replayed using RTKplot, overlaid on video showing the test environment. Green dots represent RTK Fix points; orange dots represent RTK Float points. It showed RTK Fix being maintained in environments where other low-cost RTK receivers would change to RTK Float or have jumps. Even when changing to RTK Float, accurate positioning is still being maintained without any jump. This more robust performance is coming closer to what people expect with more expensive dual-frequency RTK receiver for autonomous applications.

Currently this is using our S2525F8-BD-RTK GPS/BDS receiver. We would like to make similar improvement to our S2525F8-GL-RTK GPS/GLONASS receiver, but require some assistance logging 20 minutes of static data on 3 separate occasions using two survey grade base and rover antennas that covers L1 GPS/GLONASS in Europe and North America where there is EGNOS and WAAS signal respectively. 

If anyone with suitable survey grade antennas living in North America or Europe kind enough having interest to offer assistance, we would be happy to supply a pair of our 10Hz capable S2525F8-GL-RTK receiver evaluation boards; please send me a message. Thank you !

The THOR prototype can transition from hover to fixed-wing cruise mode by rotating its wings into ...

The THOR prototype can transition from hover to fixed-wing cruise mode by rotating its wings into alignment

Conventional multicopter drones are excellent at hovering and VTOL, but they can't cover long distances as efficiently as fixed-wing aircraft. A team of students from the Singapore University of Technology and Design is trying to get the best of both worlds with the Transformable HOvering Rotorcraft (THOR). 

THOR is just a prototype at the moment, but it has plenty of potential in industrial applications The Singapore University of Technology and Design is trying to improve on classic monocopter and hybrid UAV design with its THOR A look at the way THOR transforms from hover to fixed-wing mode A breakdown of the components in the THOR prototype

According to the design team, the THOR is based on a concept raised in 1913. Called the monocopter, it was "structurally efficient" – the whole frame is used to generate lift – but "strategically inefficient." The lack of counter-rotational systems meant the pilot and cargo would have needed to spin with the rest of the aircraft, making it impractical to actually ride in.

The Singapore University of Technology and Design (SUTD) isn't alone in trying to revive the monocopter. Lockheed Martinand MIT have both created monocopter-style concepts that have their roots in nature and were designed to explore how the idea could improve current UAVs. 

transformable-rotating-hovercraft-stud-10.JPG?auto=format%2Ccompress&ch=Width%2CDPR&fit=max&h=700&q=60&w=616&s=b8f72f29bd1123bc8afb224e77167339

According to the team, the design of THOR improves on the basic monocopter design in a few new ways. The first involved a second wing – and yes, that means it isn't a monocopter anymore. Lockheed Martin's design only used one wing, but the SUTD team have fitted two wings that protrude from the center of the UAV. 

STUD took inspiration from the samara seed, a flying tree seed that can be carried long distances by the wind because of its inherently stable, wing-style shape. Although some variations of the seed look like a single wing (or propellor blade), there are other "two-winged" examples as well. 

The THOR's opposing wings are mounted at right angles to each other and rotate into alignment when making the transition from helicopter-style hover to fixed-wing-style cruising. The students have also created a passive system to shuffle weight around based on flight mode. When the craft switches from hovering vehicle to fixed-wing aircraft, or vice versa, the centrifugal force involved in the switch is used to move the ballast into a position to keep the aircraft balanced.

It's just a prototype at the moment, but the THOR concept could be useful in a huge range of industrial environments. Agriculture, surveillance and payload delivery are three areas mentioned by the SUTD team, who say that most hybrid UAVs are only efficient in one of their flight modes. 

There are still a few tweaks that need to be made before the project is ready for public consumption. To make sure it doesn't just drop from the sky if there's a problem, the team is working on an autorotation system that will allow it to glide down safely without power. 

The THOR prototype can be seen hovering and transitioning to cruise mode and back again in the video below.
