Using a drone to get string over something high?

I have an idea that I wonder if anyone’s tried here.

In essence, the same use as climbing throw line but higher:

  1. Tie some string (maybe dental floss) to my DJI Mini 2
  2. Fly it up over a tree branch / ledge / obstacles
  3. Land the drone in the other side, without getting tangled
  4. Detach the string from the drone
  5. Attach rope to the string and pulley it up and over
  6. Make use of rope

Has anyone tried this? Is it stupid? How would I avoid the string getting tangled In the props?

In case anyone wants to know why…

  • Why not?
  • Climbing, zip line, rope swing, etc
  • Hold up a tarp or various other things

Thanks

I’m sure someone somewhere does this everyday and is doing it now as we speak.

Power cable companies around the world use RC helicopters….

My concern (slight hesitation) is getting the drone down the other side, ensuring nothing gets tangled. Is that nothing to worry about, as long as there’s enough slack?

My first thought too. But a fishing drone technique might work.

They are used to carry a line from a rod and reel several hundred metres out to sea. My understanding is the line is weighted and it is suspended from the bottom of the drone by an almost horizontal piece of wire, pointing slightly upwards. When the grop zone is reached the pilot hovers and yaws the drone 180 degrees the flies further out to sea. The line drops off.

I think nylon fishing line would be more manageable than dental floss - but I will provide the (constructive?) criticism, you can do the practical tests :sunglasses:

My concern would be the string getting snagged or being caught up in the props on decent. I use an arborist throw bag and line.

I am sure Chris @clinkadink has done something like this before

He does lose a lot of drones and is an expert in rope, ladders etc :joy:

@macspite Fishing drone style looks like it could work well, thanks.

Getting some fishing line is a better idea. I have dental floss already, which is where the idea was from. A 50m spool is about £1 and just a couple of grams!

@clinkadink that’s impressive. Hoping I’m not going to need to try those techniques myself!

Since Tim @timxjr1300 got his drone stuck up a tree, I always keep 30m of nylon rope connected to a lead weight in my kit bag. Cheap as chips but very effective.

I have also got 30m nylon rope and a weight in my rucksack… it’s always with me when I’m out with the drone :grin:

I thought that’s what your crossbow was for :crazy_face:

Hi all
Silly question ( as usual :smile: ) why do you guys carry the nylon string / weight ? Am I right in saying if it gets stuck up a tree ? Do you have to try and lasso it down as such ? Sorry for the question never heard of this before so just curious !
Thanks :face_with_monocle::thinking:

To retrieve drones from trees. It’s not 100% effective, as it depends on the tree and how accessible it is.

You hold the rope spindle in one hand, feed out about 4 feet, spin it with your other hand, and let go (whilst still holding onto the spindle). The weight carries it vertically up the tree, and the aim is to snag a branch, shake it, releasing your drone. You then pull the rope/weight down once the drone is down. Kind of like a cross between Bolas and Rope Dart.

I know of one person who tied string to his drone in an attempt snag another drone in a tree and hopefully pull it free. The string below his drone got caught up in the tree, his drone continued to pull as much as it could, and the string attached to his drone pulled a leg of the drone to the folded and closed position. That was it for his drone - down it came. Thankfully it didn’t remain snagged in the tree, otherwise the score would be 2 zero in favour of the tree. I guess the lesson is, don’t attach the string to any part of the prop arms.

Basically trying to fish it back out the tree ! :face_with_peeking_eye::smile:
