Bee hummingbird-like robot

Good whatever time of day it is where you are!

 

  1. Is it physically and theoretically possible to create a full visual replica of https://en.wikipedia.org/wiki/Bee_hummingbird and make it into a spying autonomous flying robot which theoretically could fly from one house to another, record some video footage and fly back to host (base) to upload obtained data, recharge and then repeat the whole process. Rough and early example of such machine is already made: http://www.avinc.com/nano
  2. Is it physically and theoretically possible to make the aforementioned robot fully invisible in optical spectrum (which will made him a better spying machine) by using https://en.wikipedia.org/wiki/Metamaterial_cloaking technology.

 

P.S. If take into account possible autonomous battery this http://techon.nikkeibp.co.jp/english/NEWS_EN/20140224/335902/ technology can be employed.

P.P.S. Again, I am talking about physical possibility, that is after overcoming current technological constraints.

Thanks for your time, Ivan, Saint-Petersburg, Russian Federation.

Yes but we don't need to recharge we have wireless electricity. So as long as the drone was within the field it will work. The other option is that it recharges battery within the field and then has a range it can fly within for a while and return.

 

Though hummingbird size is a bit big maybe a fly.

What about buzzing (a fly-lke) or humming (a colibri-like) sounds? Wouldn't they be attacked by local birds, for example? What if it is not a house, but project, built from reinforced concrete and somebody will cloze doors and windows when leaving home? You state, that such drone can be build and operated, but how long will it survive and remain truly undetected (taking into account produced sound) and the need for wireless charging/communication?

No chance a bunker etc could scramble the signal from the drone. There is ways of blocking wireless communication.

Well considering you could land the drone somewhere inconspicuous and just record sound or video it depends on what the security procedures are. If for instance a security team checks rooms once a day then you will need to be gone before the check.

This is a problem with most small drones. You could spray the drone with repellants etc and if it is hard to see it is less likely to be a target.

In most secured areas the whole idea ruins. Here are some possible reasons: 1. awareness of personnel 2. lots of rooms and therefore doors, so possibility to get trapped and discharge. 3. CCTV's coupled with motion detectors or just motion detectors - the most convincing reason, imho.

Besides, antennae for wireless charging probably can't be made invisible, they will be huge (in comparison to robot size) and inductive wireless charging has 2 meters range max as wiki says.

Well yeah that would wreck the whole thing.

Not if it is small enough and you can interfere with them.

Yeah but why waste all that electricity unless you're like the NSA and wanna be super high tech and expensive?

Also do you know just how light this thing would have to be? It has to have the lift coefficent of a hummingbird!

Also do you know just how light this thing would have to be? It has to have the lift/weight ration of a hummingbird unless you change your lift coefficent. Also center of mass vs center of lift is a problem too.

Yeah but MIT has one the size of a fly so I know it can be done.

It would allow for a smaller drone as a battery takes space and adds weight.

There is always an arms (spy tech)race. The smallest insects are fairy wasps, which are about the size of large amoeba. Think in terms of many of these tiny drones being released by various parties, some for spying, some hunter-killers to remove opponents drones. Imagine a bug war almost invisible right in your office and kitchen.

Yes but at the cost of massive amounts of electricity which would in turn economically be FAR more expensive that a simple battery, Even if you have to make the lift coefficent greater, Remember Air is a horrible conductor.
