Check out Elbit System's new Explosive drones
 

These are pretty neat. They have had explosive drones like this in the past. But these are smaller.
I don't think they will be able to sneak up slowly like they do in the video. Unless your enemies are deaf.

Imagine someone saying something like this to WW2 soldiers in the early 40's: "In the future, soldiers will team up with FLYING AUTONOMOUS ROBOTS, complete with micro cameras, and on-board computer BRAINS, that can fly through buildings, identify and tack the enemy, and communicate with satelites and each other to assist you.

Mind blowing...

I read your title as 'Fitbit' !!!

I though 'Wow! Thats certainly a diversification!!!' :1orglaugh

It looks like its part of a cut scene for a video game :1orglaugh

I'm in a few drone groups where a few members have been designing quads and 3d printable parts for anyone to download and build these types of drones. Most of it is done with open source or free to use software and inexpensive and easy to source Chinese parts.

Both sides are making use of this sort of stuff.

very intresting, israeli weapons are very good
