[@dmitryplatonov]

Optical flow sensor also picks up your angular movements. You need to estimate flow created from tilting (via gyro and lidar) and substract it from from flow sensor reading. While doing so, beware of different latencies.

[@Qwarzz]

This was my first thought when I saw what the sensor is doing. Any pitch or roll will give velocity from the optical flow even if the thing isn't really moving anywhere. Not something I would want to try and figure out...

[@smialekpawel94]

Well, as a UAV manufacturer I consider your design preaty well made, yet it of course can be improoved upon. The biggest problem you have encountered is generally the problematic nature of PX4Flow. I've been there. As of now VOXL Cam seems to be a much better soultion as it includes stere camera sensors which, at least when used on Ardupilot, seem to be dooing a great job. Also - usually the LIDARs used in integrated solution have very limited range and are prone to feeding the flight controller flase data. Here even a lightweight and low cost sensors like TF-LUNA seem to be doing a stellar job. I also might have ideas about further testing and even improoving your cyclorotor design and would be happy to cooperate with you. If you are interested - please, reply to this comment. All in all - great job.

[@DiverseGreen-Anon]

hm.. VOXL Cam looks like it is really great and would indeed offer an improvement but... have you considered that it is also almost 10x the price at about 1500$? 😅 which is just ridiculous for a small drone-phone case! PX4Flow is

[@AerialWaviator]

Brilliant project to tackle and demonstrate as a flying prototype! You solved so many aspects to making the flying DroneCase a usable product. This is many levels beyond using an extra long extended selfie stick. Now feeling the need to build a DroneCame to experiment and explore, as way more fun! The one challenge I see remaining is adjusting the optical flow for when the DroneCase is tilted significantly from vertical as it try's to maintain position hold (6:00). ie: differentiate between horizontal motion and secondary tilt of DroneCam related to position hold (particularly in a dynamic environment with variable wind). While lidar distance to ground is easy to compensate as tilt angle is known; the optical flow device would see massive motion as DroneCase tilts more than a minimal angle. At 6:24 is an example were optical flow would be swamped (or lost) by large path differences relative to the ground below. If optical flow had 2-axis gimbal, then a 'normal' reference to the ground target could be maintained; at the cost of added complexity (and weight). Alternatively, think it would be easier for DroneCame to maintained a constant radial distance to the subject. If (camera subject of focus) had a remote dongle, then DroneCase could use a bluetooth signal strength to get "range" data. This could help with when adjusting to larger position deviations (associated with larger tilt angles), and optical flow could fine tune position when tilt angles smaller. As a bonus, if the remote dongle had a compass, then when the subject turned, or moved the DroneCase could move in an arc at constant radius to the updated subject orientation. Obstacle detection would then be required. Again, is brilliant how identified core features and avoided the spiral of feature creep. ;)

[@thomaswiwchar1661]

Wouldnt the tilt of the phone rocking around add to the misreading of the velocity sensor? Because the phone dosnt stay in a fixed vertical position it rocks back and fourth, even though the drone may be stationary above the ground as the phone wobbles and rocks it will give it false readings. Mabye some vector math between a gyro sensor and your velocity sensor could correct for the rocking angle of the drone?

[@NicholasRehm]

PX4Flow does this compensation onboard, but I think mine's gyro went bad and it wasn't doing compensation anymore. I tried to do this my self in the flight controller, but it can only work so well...

absolutly awesome. what a great project!!! You proved that "myth" possible like the real "myth busters". incredible!!!

[@Demongornot]

Great, I love it ! One thing you could do would be to use your phone's camera with a self made app to do face tracking and compute your phone position relative to your face but also relative speed, then, the app could send position adjustments requirement to your drone (through USB-C for Androids and Lightning for iPhones), as smartphone have more than enough computing power on their own to do that. Your phone would send position request, drift speed from the target, and your phone already get drift speed from stationary and altitude. One extra step could be to apply targeting from your position holding camera, making it able to not just get the relative speed from the gound, but also, to try and get back to the same initial point and hold it, making it much more stable than only reading horizontal velocity, as you now have a precise point to follow, only downside is that it wouldn't work in a totally uniform ground by lack of easily recognisable details (where speed can still be established) or a too complexe one (where it would looks more like noise than specific single target to hold onto). The only downside of using a specific app, is how the phone won't be able to take 100% of your camera's capabilities as only the native phone app is made for it, so you will have, at best, what other apps (Instagram, Snapchat, etc) can do, meaning, the default camera feature, so, no zoom, macro, portrait, etc. Though, you could try to run your own app in the background and order your phone to take picture with the main phone app through ADB commands.

[@MichaelRyannz]

Would be better to use the phone processing power.

[@sebidotorg]

@@MichaelRyannz One of the things making the flight controller work so nicely should be reliable execution times of each command to the rotors. Just imagine your drone crashing because Twitter was refreshed in the background, keeping the CPU busy at just the wrong time. I don’t think your phone allows you to run real-time code, does it? That said, using the camera image itself to measure optical flow and stabilise the position via an app on the phone sounds like a really nice idea, if there was a way to do that.

[@nocare]

​@@sebidotorg Optical flow boards use dedicated circuits to process the imagery. The phone just won't have the processing power to do it at a decent rate with a low enough latency. The px4flow is just a really old board. If you want to spend the money the herflow is a similar package that integrates the lidar onto the board and weighs 1.2 grams compared to the px4flows 30 grams. Runs at 50hz. Probably save 60-80 grams vs this prototype design. If you really want good performance you get a machine vision camera with a 80hz-400hz global shutter sensor and have that do the flow tracking for ya, but that adds all the weight savings back on.

[@sebidotorg]

@@nocare That’s what I thought. While it would be nice to use the actual image you want stabilised as the source for the movement information, I didn‘t think the image processing on a phone would ever reach a latency that‘s low enough for such an application. Which refutes the comment that it would be better to use the phone‘s processing power. Thanks for your input!

[@nocare]

@@sebidotorg No problem. Also if you want to have a target you place on the ground to track then you can do what you wanted using the machine vision cameras. Such as the OpenMV camera and others like it. Aruco tags and April tags are examples of fiducial markers. From just 1 tag you can get the position and orientation of the camera in 3d space relative to the tag. Conversely you also have the tags 3d pose as well.

[@danilohalboth3722]

Would it be possible to run this off the phone? And all the control of the cam-copter could be done via a phone app(?) It would slim down the amount of components required, possibly by quite a bit.

[@KaliKavala]

I've watched the videos from the other guys. They were not interesting and imo failed. I am glad that you have done such an amazing job. :) Good work. One thing i have in mid about it is - ur propelers have too much space to the ducts (pipes around them). This looses some performance. The less the space between the blade and the pipe , the more efficient it gets. You can try cutting and sanding the props and make them kinda "bull nose". Then make the space as little as you can. For a bonus point make the upper part of the ducts curved outside like 180 degrees or smth. This makes it even more efficient FOR LIFT. Making those changes could help you a little bit with stability but should help you with battery life too. Oh do not forget to balance your props (even new they are not). Use magnetic balancer as it is most accurate. Hope this gives you some ideas :)

[@NicholasRehm]

Agreed--ducts were mainly for protecting my hands. The first set were pretty tight on tolerance, but as you saw that led to some problems with resonance and prop strikes

[@VulpeculaJoy]

I think fusing the IMU and the optical flow measurements with some Kalman filtering could make it much more stable.

[@NicholasRehm]

That falls into "filtering tricks" category ;)

This is a good idea, and if someone has not contacted you about producing it commercially, then they should.

Could the data weirdness from the flow sensor be due to what it's actually seeing? Typically they work best with a sharp contrast pattern and yours is a long way away from what it's tracking (the ground). Also one thing I just thought of is that with the sensor hanging off the bottom, it has a pendulum effect to it's vision cone, too - Every time the platform attempts to stabilize, the sensor sees a shift due to pendulum.

[@NicholasRehm]

PX4Flow has angular rate compensation built in but I think the problem with mine was that that wasn't quite working...maybe bad gyro

[@eVITORIOe]

You have all the capabilities of what snapchat has with their drone but yours is much much better!

[@StormBurnX]

The only addition to the stabilization approach that I can think of is to use the gyro to calculate an offset in the optical flow data. If the drone is hovering perfectly but pitches in a direction, the camera lens on the flow calculator turns to point in a different direction, and it reports this back as velocity/flow. Therefore, using the gyro data to detect actual flow vs camera-tilt-flow could help. (Used this technique on some balancing bots which, surprisingly, have shared a lot of the same control loops as drones, who'd have thought.)

[@NicholasRehm]

PX4Flow does this onboard, but the problem with mine I think is that the gyro on it died. So part of my 'filtering tricks' included doing this compensation manually (poorly) in the flight controller code

[@StormBurnX]

@@NicholasRehm Oh, gotcha! It's nice to know a sensor like that has that capability (even if it doesn't work on your board) I've always wanted to get into optical flow stuff but the quality seems to be either low, or the price high, compared to just using a cheap camera

Got to say nice job... when I saw the fake version about a year ago I thought right away - why not? And then I was thinking how this could be helpful for many situations. So I set about designing one as well but I used a 3 motor config thinking that would help with the fore and aft motion and overall stability... but looking at your design I like yours better... a lot better! And for several reasons - more compact, would be easier to carry, one less motor, shroud and prop, looks lighter so it should get longer flight times... To be honest I got in over my head trying to figure out how to control it and I was getting some help but that was slow and intermittent. The idea (if I have it right from the electrical engineer) was to use an accelerometer to detect and control motion and some kind of sensor to keep the height steady... Although he works in aerospace his background is not in drones and I think that complicated things... work got truly frickn nuts so my free time disappeared and to be honest I am super stoked to see your creation - it is cool to see the concept validated and done nicely. I do have a few other "features" that I was thinking of, but they are prob. something that everyone is thinking about. Anyway, really great job and a seriously fun and useful gizmo!

[@kwinvdv]

For the velocity control are you using the raw optical flow reading or are you also compensating for the tilt and roll of the housing. Namely, if the housing tilting back and forth from vertical, then the optical flow sensor will also read an oscillating velocity. When assuming that the altitude stays constant and the ground is horizontal, then one should be able to subtract this induced velocity (assuming the attitude is estimated accurate enough). A dirty solution could also be to filter the optical flow sensor with a low pass filter and/or notch away the typical attitude oscillations.

[@NicholasRehm]

PX4FLow does angular rate compensation onboard but I think mine's gyro was broken with age. I tried doing this myself manually, but it could only work so well... Lots of "filtering tricks" were tried

[@StrikerGoingDark]

[@DanielCrist]

This is really cool. Great work! I know that with a DJI Mini SE being just over $200 now, it doesn't seem like this could be a viable product, but with a few minor improvements and the right marketing it could be. If you could get the battery life up to 10-12 minutes, and could maybe give it say 3 height settings and 3 distance settings with a lever to automatically adjust for those 9 positions, and a timer to hold those 8 further positions (maybe with 3 settings as well), I'm confident I could market something like this for $150-$180 easily. It's all about finding the right angle to convince someone why they need something, and having a novel and unique presentation like this helps distract consumers from the fact that there may be other tools to get the job done more effectively.
