No and not even close. Look up Betaflight (racing oriented) and iNav (navigation oriented). Ardupilot is more integration/mission oriented, but it's far from the only game in town. A small The all-in-one PCB integration strategy is cute, but I really don't think it's a great approach from a crash-recovery point of view.

I don't know much about the drone space to be quite honest but I always wondered what it would cost to mess around with swarm algorithms, on actual drones, without breaking the bank. Any pointers?

With ArduBee initiative we are making our best to innovate creating our best solution for swarming, with micro drones, indoor and even outdoor, based on Ardupilot Open Source project. If you have a look at https://ardupilot.org/copter/ you could start to have an idea of the included potential.

> The all-in-one PCB integration strategy is cute, but I really don't think it's a great approach from a crash-recovery point of view. Spot on. However, it's a nice way to lure you into building a quad: just put some motors on, and you're good to go. Fly once, crash, and then go actually build a proper quad.

Small quads generally do remarkably little damage to themselves in most typical crashes. Remember this thing only weighs 102g, and half of that is a battery held on by springs. In typical indoor use (can't get more than a few meters high, unlikely to go faster than a few m/s), this'll crash way more than one time before it show any signs of damage to anything except the (replaceable) props. (Sure, you won't be handin…

I totally agree with you, it's the most compressed form, in a slim electronics layer, for the most lightweight design. Every grams are used for the best selected components, assembled with passion and fully supported by Ardupilot firmware.

Till 1 year ago it has been a great concern, especially for small drone. Now thanks to andyp1per, new Ardupilot dev, we have amazing results with dynamic filtering gyroscope noise, we could even track the mechanical noise peak based on actual RPM or live FFT. Harmonic Notch Filter in Ardupilot https://ardupilot.org/copter/docs/common-imu-notch-filtering... new and ongoing development https://github.com/ArduPilot/ardu…

This was about mechanical strain from vibration.

You have to consider under the selected IMU, in the center, there is the most of the mass, made by the single 18650 Li-Ion battery. This solution is working, ArduBee is already flying good with the low pass filter in the gyro sets at 110Hz, if vibration would be an issue I guess it cannot fly

Looks cool, it's great to have another good open source ready-to-fly option. I have some concerns about larger PCB quadcopter designs because I can imagine that fatigue due to flexing on the PCB over long-term use could cause issues with the PCB delaminating or solder joints failing. On the ArduBee particularly, you can see a lot of surface-mount components mounted on the arms. I'd love to read more about any lifetim…

We use the same design in the big brother for 5" propellers and double the weight of ArduBee. We make this development for our main focus about performative drone for swarm choreographies, its 2 years working with the fleet testing everyday to improve the quality of the performance. We had a lot of crashed indoor, and the pcb never had serious harm. We do not race obviously or high speed onto the wall!

Again, this issue is not the IMU, it's the whole thing breaking mechanically.

That's great to hear that you haven't seen any issues with the PCB design. Thanks for all the great work!

That's really it: you can grab all the code and schems from there. There was a community but it shut down when the FAA regs about drones >250grams came out.

We are trying to shape ArduBee as an excellent platform for 100g-200g micro uav develop and to enable urban swarm experimentations, indoor and outdoor!

Very cool, but in that case definitely give Parallax a poke since they've been doing it for a while, it may save you some time and some mass.

Thanks! I'll do it, I've never visit Parallax site before
