We have faced many issues since last post.There were problems with HDMI input on the board we use: it didn't work with some cameras or latency was too big in some cases (even around 400ms). Thus we decided to find a good navigation camera with lower latency. At this moment we can offer
Main news is that we eventually have advanced to radio link tests. On the attached video which was captured from ground display you could notite multiple frame drops (and even rare ones right near receiver) which were for sure caused by unstable WiFi connection. Hope we will find a reason for such a poor performance soon (like not attached antennas or so).
Since last announce many parts of our software have been improved: we have better video stream recovery, it is possible to see radio link statistics and configure various components with a bundled configurator application.
During all this time we've received a lot of emails from interested companies and individuals. We're really happy that there is such a big interest for the solution. Although it was told many times that the product is going to be available in 1-2 months now we realize that it was way too optimistic. At this time we wouldn't give you any expectations but saying only "It's done when it's done" :)
So now we are proceeding to radio links testing (mainly WiFi ones at the beginning) and since all other system components are pretty stable we expect things to go much faster. There should be more news followed by flight test footages.
We are very happy to tell that SokilLink is very close to release. During last few months there were many improvements implemented thus making the entire solution much more flexible and reliable. We have also taken into account your wishes and now want to tell you more about the...
You may remember that entire idea of our development was to make something similar to 3DR Solo on-board PC but much more lexible. In Solo there were two computers: one in the drone itself and another one in RC. So we're going to ship the same boards set.
Ground PC is an Intel-powered board performed in PicoITX form-factor. It has 2 USB inputs which allow to connect USB gamepads/joysticks or an USB trainer dongle which allows to use our system with conventional RC like Turnigy 9XR. There is also a HDMI output which allows you to see HD video stream from your drone and telemetry overlay. Air PC is an i.MX6 board and is only 35*70mm. There are also an USB port, HDMI input for digital video and two DroneCode-compatible telemetry ports. Both boards have mPCIe port which allows to use high-power WiFi radios.
Mainly our system uses WiFi as data link, however we realize that it has some limitations. For those who need more long-range solution we're happy to announce to tell that we're also working on integration with one 3rd-party data link which allows to stream HD video up to 25 km.
It is hard to build a drone similar to devices represented on market these days.One may succeed in making UAV with great flight characteristics or payload, however it is much harder to integrate all drone device into one working system. There is always demand in video and control links. Knowing more info about drone systems is also good, so telemetry link is also often a requirement.
For Pixhawk-powered drones often the only solution is to use 3 different radio links for each kind of control. Situation with video is the worst: in many cases only old good (well, not so good) analog video transmitter can be used. But that's not last problem: all these transmitters should be placed on the drone frame and protected from influence of each other.
So we've decided to build a solution to solve all these problems. It had to give all features provided by each separate system (RC, telemetry and video transmitter) and much more. We also wanted one radio link to be
used for all kinds of data.
So main features had to be:
- Using Mavlink protocol for all types of controls
- Digital video transmission from drone and displaying on RC screen
- Cameras control using their API
- Using USB HID devices for manual UAV control
- Flexible structure for easy integration...
And now we're happy to present SokilLink. It is a complex software solution for building a powerful drone. We are sure that it would give you all required functionality to compete on the market. Just contact us and we'd be happy to answer your questions and help you to make your product better!
