This might interest you guys, whilst away on business last week I decided to fly my Tello...in an lift
SHARE this with your friends and ask them to BET what will happen once the lift moves up, and down!

interesting experiment! i was actually expecting the drone not to touch the floor when the lift was going up

Yeah it has tricked quite a few people this experiment!  Hope that you found it useful, share it to your friends and ask them to bet on what will happen!

The same hear as the bottom sensors should keep it from doing so but not going down.

Somebody has to test the same with a phantom pro: blender chamber

Haha, if you supply the P4 Pro and some prop guards, then I'll supply the chain-mail armour and give it a try

Infrared sensors have a lot of latency, hence the lift ascends so quickly that the drone doesn't have time to react. Plus, if you go out now and test fly your Tello, then ascend your hand up towards the bottom of it, you'll find that the Tello does nothing because the IR sensors aren't used for 'obstacle avoidance', only to detect a hand during palm landing.

So what settings were you using during this experiment?  You commented on them, but i missed which you were using.   Or would it really matter?     Interesting video.  Thanks for sharing..

The settings were all stock, no modifications, entirely factory settings whereby the Tello relies on its barometer for altitude control.

experience very fun
thank for your happy style

That was actually very cool!

I wasn't expecting it to hit the floor while ascending...

wow interesting experiment !

Thanks so much for the comment, I like to keep happy so that my subscribers keep watching

Be sure to subscribe, also share the video and ask your friends to guess what happens! I have some more ideas for experiments, keep watching

This is NOT what happens with my Tello
"... test fly your Tello, then ascend your hand up towards the bottom of it, you'll find that the Tello does nothing..."

My Tello definitely will fly upwards away from a hand, but it is not entirely consistent. I suspect the times when it doesn't do that are probably due to low light or some other effect reducing the ability of the Tello to see what is below.

Putting a hand under the Tello (with prop guards on, flying inside) can cause it to fly up to the ceiling and stick itself there with the suction from the propellors.

Good experiment.

Very interesting... Thank you for sharing.

Now I wonder what would happen with the Mavic Pro or Phantom 4 Pro?? Are they any smarter??

All the best

OMG,aren't you worry about when the drone crash to the top

No not at all, the Tello is a solid little thing, and impacting the ceiling in that way won't do it any harm.

I had the same question.  Thanks.  I wonder what would happen if the setting are different?

Thanks for sharing

people have a lot of time on their hands

not very safe to have a spinning meat grinder in the same space as you

I agree.
also, my wife would never agree to drive while I'm trying to fly a MP in the back.

Yeah and these car tests are thoroughly boring and predictable, that's why I did the elevator experiment as I don't believe that it has been done before with any DJI drone!

I watch the full video and this is a very useful experiment, keep sharing this types of video so that people view this and use this properly. I also view some interesting and exclusive videos on bitfinder related to drone work and many more things if anyone is interested to know more they can also visit this site.
