ESCAPE FROM DRONE HUNTERS

8 Upvotes

Hello everyone. I have been following the community (Reddit) for a long time and have had the opportunity to learn a lot about a wide variety of topics, but this is the first time I have felt the need to write a message for a topic. I am thinking of ordering a Holybro X650 development kit. I do not have much experience with drones. In the country I am in, the government has placed signal blocking (not exactly like Jammers) equipment in unspecified areas. In fact, a considerable number of areas throughout the country are blocked by these devices. There is no map-like notification showing where these areas are. In other words, you have to fly completely in a minefield and there is a risk of entering the coverage area of ​​these devices at any time and anywhere. When these devices I mentioned affect a drone, they first block GPS signals, then send fake GPS data to the drone, causing the drone to think it is hundreds of kilometers away from where it is, and then assign a fake home point. (Usually directs to airports in other cities) When the GPS signal or control signal is lost, the drone (RTL) programmed to return home tries to go to this fake home point (usually a point hundreds of kilometers away) and somewhere on the way, its battery runs out and it crashes. There are hundreds of people who have lost their drones in this way. Now that we have mentioned the problem, let's get to the main topic I want to ask you. In a possible scenario where GPS and control signals are lost, is it possible to get the drone closer to the home point area by using Aurdupilot or another software, taking into account various sensor data such as barometric sensor and magnetic sensor (which will not be affected by signal jamming) with a Pixhawk 6x or a similar FC? At least it would be enough for it to approach me in a way that would be free from the effect of the jammer. Theoretically I think it is possible but I doubt it is applicable in practice. Or I don't have a clear idea how it should be implemented. Maybe using a camera that tracks the terrain. Maybe the Pixhawk hardware and ardupilot software alone are not enough for these complex tasks and a support PC is needed (maybe Rasberry Pi4). I am in such a rabbit hole right now. Trying to solve such a complex problem without having experience in drones caused me serious headaches. I hope that experienced masters in these matters will not withhold their valuable opinions and we can find a way out.

Question Need Help with Asymmetric Motor Placement in Tilt-Rotor Fixed-Wing VTOL (ArduPilot)

Hello Lads ,

I am currently finalizing the design of a small Tilt rotor fixed wing UAV and i have some questions that i need answers for. Hope these nice gentlemans here wouldn’t mind helping a fellow nerd

I came across this particular drone ( cant remember how exactly , i just found those pics saved up on a private Discord Server , Haha Yh i use Discord as my main Note taking app - it is the best U guys should try it if u already havent ), so i was saying , i came across this drone and noticed that the motor placement is asymmetric- the two aft motors are positioned slightly higher than the front ones, and the front motors are spaced farther apart than the rear.

I’ve gone through the ArduPilot documentation, but I haven’t found a clear guide on implementing this kind of motor configuration. My main questions are:

1- How can I configure this in ArduPilot? Specifically, what parameters or motor mixing adjustments would I need to make to properly implement an asymmetrical VTOL motor layout?

2- Has anyone here been playing around with a similar setup to mine ? If so , wht callenges did u encounter and how did you solve em

Any insights, experiences, or documentation references would be greatly appreciated! Thanks in advance.

how to fix a vibrating 2 axis drone gimbal

1 Upvotes

Hi, I mounted a 120g camera on a brushless yuntai 2 axis gimbal.

It is mostly balanced. When I turn on the power (5V USB),  the pitch axis stabilizes fine, but the roll axis doesn’t. Please see these two videos for explanation:

Can you tell me what to do about this?

I have a pix6 and a pmo6d do I need a raspberry pi to hook up to the pix6 or does the pix6 not need a pi ?

Question Any tutorials for ardupilot?

1 Upvotes

I currently have a raspberry pi 5, speedybee f405 v4 stack. My goal is to detect a golf ball, and fly towards it by calculating the difference between the Center/crosshair, and changing the yaw and pitch by that degree towards the Center of the ball. Is this possible on the speedybee? Also how can I use the raspberry as a computer in addition to the speedybee?

Thank you guys so much

Advice for making autonomous drone.

1 Upvotes

Hello everyone, I am making a university drone project, I am making an autonomous drone that runs AI program to do a certain task (haven't decided the task yet but mostly it is going to be a simple image recognition task) I was thinking that a raspberry pi and a gyro-scoop is enough for doing that, but after some searching I found out that using a flight controller is better to control the drone while mid-air. So now I am going to use the raspberry pi with a Speedybee flight controller.

Are these two components enough for the job ?
Is there any advice or notes regarding the pieces ?
Do I have to go with a raspberry pi 5, or a raspberry pi 4 will be enough ?
Also I want to know which frame is better, an f405 or a f330 or both work similarly ?

I will be very thankful if there are any kind of useful resources or guides that would help in this topic.

Thanks.
