Autonomous drone with LLMs

Drone autonomously searches for TV then advancing towards it
Next: more advanced objectives that require more planning and real-time feedback analysis.

https://x.com/hadiazouni/status/1856298163054796967/video/1

The final goal is to have an autonomous drone swarm with a leader drone that contains the LLM and all the intelligence, and smaller companion drones that help execute objectives.

4in1 ESC proper BLHeli32 setting for VTOL

Hi, new to BLHeli32 and 4in1 ESC.

What is the proper default settings for a 4in1 ESC in a 4+1 VTOL plane?

There is throttle settings which sure are different than a quadcopter setup?

BLHeli32 programming without ESC

New to quad and 4in1 ESC so please bear with me.

I need to configure a new 4in1 ESC and I understand it can be flashed if it is connected to a flight controller. I'm not using a traditional flight controller so in my case I would need to use a USB dongle to program.

Would something like this work: https://www.amazon.com/gp/product/B0CCXGFSB3/ref=sw_img_1?smid=AW16MM68RL9BH&psc=1

Most of the tutorials I see have the ESC connected to FC and they use INav or betaflight etc. I'm using Ardupilot so I'm not sure if will pass through which is why I'm asking about the USB dongle option.

WiFi drones with Acro mode?

Has anyone found a cheap wifi drone that can do Acro/rate mode?

I am thrilled with the Cheerwing Amazon-grade camera feed, but why don’t their controllers do manual? Clearly they can do a flip

XT60 to USB-C quick charge?

Every once in a while I end up not using the batteries I charged and I'd like to discharge them using them as "input" of my HOTA D6 Pro.

I managed to use the USB-A port (5.0V / 2.0A) but I'd like to use the "Power Supply" mode with the XT60 as ouput.

Does a cable that converts XT60 to USB-C (quick charge) exists? I can only find the other way round

What are some methods to keep the VTX antenna (relatively) protected?

I feel like there are ways to keep this from happening, especially the way I crashed. How do you like to secure your antenna, and how do you usually fix it? I figured I’d just use electrical tape for now.

When I use a switch SB in RadioMaster TX16S to switch rateprofiles, it skips 2 rateprofiles, why?

I'm using channel 3 in my TX, I then do this in adjustements

If Enable = on

Full Range Active

Then Apply = Rate Profile Selection

Via Channel 3

I'm using the SB switch, but when I go to PID tunning and try it, the switch only goes between rateprofile 1 and 4, it never touches 2 and 3. It completely skips them.

Up position is rateprofile 1, then middle and down position are 4, what happened to 2 and 3?

Alternative Mavic-sized drones?

After watching this video I was wondering if there were any decent drones besides the Holybro drone that are within the size of two DJI Mavics, that isn't an FPV drone that requires goggles. Obviously I’m not getting any amazing camera onboard, though a simple view camera that can be displayed on a screen would be nice, and I'm likely sticking a gopro on it anyway. I'm willing to do some assembly if need be.

Been out of the hobby for about 4 years now. Would appreciate if the community brought me up to speed regarding how outdated my gear is and if any of it is still usable.

Hi everyone!

Been out of the hobby since around 2019/2020 and I just found my old gear in a storage box! Super happy to see that my old drones are in pretty good condition, but the batteries are probably done.

Here are some pics I snapped of my gear: https://imgur.com/a/DW96Jwu

The Emax and Mobula pre-built drones are probably in perfect condition, so I'll get those flying again first! Just gotta grab new batteries somewhere.

However I'm highly sceptical that I can get custom build with 250mm frame flying again. I remember it was already sketchy back then due to multiple crashes. Might as well retire that one and just build one from scratch in case I decide to get back into it.

My questions are mostly:

  • How much has the tech advanced since about 4 years ago regarding video tx/rx, flight controllers and flight software (I remember being on betaflight back then)
  • Is it still a pain in the ass to get the PIDs correctly to have a smooth flight or is that part a bit more user friendly?
  • Is digital video standard now or are most people still on analog?
  • Any clue which video receiver I have on my FatShark? I tried looking up True-D Furious FPV, but I cant seem to find the exact model. I need a way to debug it or maybe find some instructions, because one of the 3 hardware buttons is broken so I have trouble navigating the settings.
  • Speaking of FatShark, is it even worth fixing it up at this point or should I just get something new and much better?
  • Are those video antennas in the second-to-last pic any useful or is there better stuff out there now worth upgrading to?
  • And lastly, my FrSky X-Lite remote. In case I do get back into the hobby, I'd like to upgrade it to something bulkier with more buttons and better grip. Do you think I'll be able to sell my X-Lite or would you say it's too outdated now?

Sorry for the long post and so many questions. I forgot so many things about this hobby and I'm just trying to orient myself between all the old tech, new tech etc. and I figured it would be simpler if someone knowledgable helps me get back on my feet.

I mainly want to avoid trying to get some legacy gear up and running if I can just chuck most things away and buy newer, better quality stuff with which I'll have more fun.

Cheers!

New motor is “sticky” and doesn’t spin smoothly (haven’t powered it on yet, still finishing build)

I have a set of emax eco IIs and after I got them put on the frame I noticed that all but one of them was turning smoothly with little resistance (as in, spinning them around with my fingers, not powered). The fourth is sticking and has a lot of inconsistent stopping and sticking, almost as if it had gravel stuck in it or something. Is this normal?

I don't think I did anything to break it, the only thing I can think of is the rear screws that I put in pinched two of the three wires , though not by much I don't think.

Edit: here's a crappy video of me attempting to demonstrate this. The first one is how they are supposed to spin, and the second is me struggling to get it to turn at random intervals.
