UAV (2) Failsafe and video surveillance using RVOSD

[dhakagod]

why wasnt the complete landing shown ?

[krbosak]

@dhakagod because this time it was rogrammed to return to loiter after mission end. Then it was landed manually what is easier and faster than any automatic landing.

[dhakagod]

@krbosak understood sir :) . I am planning to study and build a UAV. Can it be made 100% Autonomous ? Like say, just tell the software the flght plan and th UAV does the rest by itself ? Take-off, climb,cruise,turn back, descent and land ? Thanks :)

[krbosak]

@dhakagod I believe you cannot make practical self-landing winged UAV for cheap.

teh field required is some 200x300m unless you have deepstall what is not worth it because you have no supply for spare parts for your custom construction.

[dhakagod]

@krbosak hmmm, mu budget is roughly $10,000 . For a complete UAV system including ground station with live FPV and telemetry. Am I hoping for too much output for that cost ? 

[krbosak]

@dhakagod I think yes, because UAV with groundstation that WORKS for any realistic civilian application comes with a van. Then, groundstation that serves anything is custom written for a task. So go figure, what civilian sector has this. For that porice you can get photomapping plane wihtout groundstation, Groundstation is in practivce one more person to the crew, a car, 309min setup time for anything. Also count in operation al costs.

@krbosak hmmm, I am thinking more of a stationary ground station, lets say a big display and controls in my bedroom and the antennas in my roof with UAV direction tracking to enhance signal reception. Later on I will think about mobile solutions for the ground station. I have got multiple investors who can help provide extra cash for the research and development of thee product. Anyways, thanks for taking the time to share your thoughts with me :)

@dhakagod you can setup this system by yourself for the money but you will spend equivalent of 1-5 man-years if you want to be near professional quality that serves anything.

Hobbystically, with 50% crash rate, you can have anything.

[dhakagod]

@krbosak I have 5 years for the project till the construction of the prototype. 2 years more for the further development of the product.

50% Crash rate ?? You mean 1 crash every 2 flights ?Thats insane for my goal, there should be no sort of failure due to any system failure. Atleast in the first 1000 flights. I am not looking forward to a hobby rc drone, rather a real drone :)

[krbosak]

"there should be no sort of failure due to any system failure."

Therefore you will certainly fail because you are assuming you must be flawless.

[dhakagod]

@krbosak lol, i did not mean it literally. What I am saying is, at least a huge number of flight should be guaranteed failsafe (theoratically). There are system failures even in Billion dollar systems. I am aware of that. However, I can not sell my system to you telling you that there is a 50-50 chance of the bird crashing :S .

[krbosak]

@krbosak if you want to rush and make a system requiring 2-5 persons by yourself for less than 10% of the PRICE of the ready product (not even its development costs) expect 50% crash rate operating it in realistic conditions. With groudnstation with the law you cannot even fly it because somebody has to keep visual contact.

@krbosak Hi, does the RVOSD 5 have gyro stabilization like the FY AP for windy flight? Is that what the IMU do? Thanks!

[krbosak]

@muffdriver69 This is IMU autopilot connected to RVOSD as pure OSD. I have a very old RVOSD here.

OSD is 100% passive here and gets teh data from FLEXIPILOT.

[muffdriver69]

@krbosak Thanks, but I still don't know what IMU does. What happens if you don't use it?

[krbosak]

@muffdriver69 Impossible to answer. IMU is one of many subcomponents, one of many ways to tell the plane orientation. What happens if there is no IMU?

What happens to the swimmer if there is no water? Who knows. Whatever.
