I don't know how I missed the Forums right beside Blog, but anyway, this is a re-post in the propper place, almost.
This question more or less belongs in every category in the book, but I guess I will present it here. I wan't to build my dad an autonomous plane which features high quality video (none of the shaky ugly stuff you see on youtube because this isn't for fun, this is serious use. It is going to be a large gas plane with a fairly large engine. It may use an engine to run a generator which then power an electric motor, but probably not. It will need to be able to fly to a location (field) then it will just circle over it while my dad uses either a joystick and a TV or the head tracking goggles to look around the field and find what he needs. The camera needs to have pretty good zoom so he can pretty much fill the whole screen with one cow, and it needs to be good quality optical zoom, and it needs to zoom out too. The plane will also need to be able to move to a new circling location with a simple click on a map, or entering of coordinates. It would also be wonderful if it could land itself either using recorded data of a manual landing, or using complex software and stuff. It would also be good if it could calculate distance to home and then using the amount of fuel left decide the point of no return and make it unreachable.
Recap: I need high quality, long zoom, live video, fuel monitoring, autopilot, antennas, amplifiers, and other stuff I don't know about.
A list of specific parts with links would be awesome guys, thanks in advance.
Any ideas for the most stable, easy to control, easy to land, and smoothest plane shape. It would also be good if it had a large payload area for equipment and fuel. It also needs to be able to handle 10-20 mph sudden gusts.
For this level of performance, at this time, you would need to purchase a $20k plus commercial type system. Actually, you would probably have to pay much more.
I was reading a post on this sight where someone had found the equipment to do 300-500 miles. I know there is a way (less than 20k) to do this (excluding the plane) I have found multiple amplifiers up to 25 watts which is more than enough. The only problem is that they are for wifi. I now think I would control it via wifi (laptop on the plane with servo controller software running and remote desktop connection), or use a 2.4 ghz channel for communication to and from the craft, then I would use a 900 mhz to transmit the video back. How far would 5 watts send a 360 degree signal.
I think the 20k would cover the camera!
Where do you find a camera that expensive, I'm only 100 - 400 feet up, and cheap binoculars could do the job.
try getting a hugin airframe its big and can carry i think a eee pc netbook 2g for full blown computer which you can connect to long range wifi antenna like engenius eoc 1650 its rated to have atleat 20km radius then get axis communication ip cameras they have pan and zoom they are available in hd 720p and ofcourse the apm 2 for brains then get a serial to ip converter to convert the apm2 comport to have it pass thru wifi too it wont cost you 20k$ usd
Mugin is like the hugin but bigger. I am experimenting with a 1 gal gas tank for 3 hours of flight. Trying to work out the generator for power issue. Check out fpvhobby.com or fpvflying.com.
Now that is the kind of stuff I can do. For generating power you may wan't to check out servocity.com they have everything you could possibly want for your mechanics (shafts, pulleys, belts). You could attach a DC brushed motor to use as a generator (use a 24v one) or you could add a second mini engine and use it as a generator. Just keep a battery in for backup. I would need about 4 hours of flight too, so 1.5 gallon tank might do the trick. That mugin is awesome
electromagnetic drop tanks on each wing. LOL. Just getting into the generator stuff. Great advice though. Any more insight on the generator? Can I repower all of the electronics off of it?
Yea, the most that the servos will pull during usual flight is at max probably 5 amps. So if you look up on board RC generator just about any of those options will work, you probably don't want less than 30watts, but no more than 75.
Awesome Idea, but farming is done in rural areas where high speed wireless isn't available unless you make it yourself (set up your own long range tower). We can get smart phone internet, but we don't have G 2G 3G 4G 5G 6G or anything else, we have the edge, which is designed to be slow, tedious, non-consistent, and non-existent. I think wetting up my own wifi tower which tracks the aircraft should work, but sending info back could still be tough even with a 3 meter mugin. Now my only question is how to view and control and HD camera. If that 200mw can go 20 km a cheap 1 watt or 5 watt amp and 360 degree wifi antenna will work just fine.
setup your own :) have this mounted on a pole and you have long range wifi http://www.worldeyecam.com/store/eoc-5610-802.11a-b-g-outdoor-dual-...
We are talking 30 miles, not 20km, so I will have to use a little more powerful system (I will be getting a license), but that is probably what I will do, but how do I communicate a live HD video feed back through the wifi
