Wash Uav B400 Cyclic Control

[kavic5150]

ok, so my choice of words was hasty. And its not a well educated person who often visits the ER. Just words of caution to all those "noob" pilots and/or parents who think these things are toys. My mom took one look at my gaui 550 and said "cute." Thanks mom.

Just from what I'm seeing in the video, it looks like the extra hardware you're using is doing the same function as the stock gyro. What other benefits does this system provide?

[seanreynoldscs]

@N1xZer0 So this is not a "SYSTEM" as you say...

The point was to demonstrate control over the larger cyclic heli.

The gyro and accelerometer would eventually be giving the embedded processor data it can use to correct (beyond what the gyro on board would do)

In actuality the gyro on board should actually be a compass.. My gyro doesnt even have force measurements in the axis of the stock gyro... A compass is a much better idea for that level of control... as long as you are on earth anyway.

No excuse for this kind of stupidity. Pilots like this one make us all look bad. Very dangerous

[seanreynoldscs]

@kavic5150 Thanks for your concern. I'm still alive... I know the danger of something in the linkage coming loose and the blade flying through me...

But beyond that... baring mechanical failure... my code was not complex enough for a bug to kill me... and the helicopter was held down with blocks, so...

It was dangerous... but not as much as you make it sound.

Arduino plattform is not a good choice to develop an efficient uav due to null, innefficient compiling optimizations and weak processors. yes, it's dummies-proof (easy) and fast programming but you'll never get a realtime responsive system if you plan to apply Kalman filtering, PID algorithms and multi sensors to work together. Arduino is just usefull to impress your grandma and your friends. Try assembler or low level C, that way, your system will rock. (i wrote you this on other of your video)

[seanreynoldscs]

@rodstartube Thats not actually true. You dont know what youre talking about. An arduino has more processing power than the computers that launched the space shuttle in the 60's... so why dont you try to use it?

[rodstartube]

@seanreynoldscs I'm speaking about arduino as a software plattform, the high level functions for fast and easy development has the cost of poor compiling optimization. Yes in the 60's that computer was programmed in a low level hardware level languaje like assembler. It doesn't fit to me someone who says to be a master of computer science, be programming in a hobbist oriented plattform.

[rodstartube]

@seanreynoldscs If you want a really realtime UAV, PIC32 is a powerfull choice for demanding engineers, it provides DMA channels for direct memory access as UART, SPI, A/D without CPU intervention, 7 interrupt levels, DSP engine, real 32-bit processor up to 120 MIPS, an infinite more features, and it has a free compiler for begin to play with. That’s what I’m playing with now.

where the hell did u learn them?

[seanreynoldscs]

Where did I learn what?

[qrrak]

Where did u learn all thoose electronic stuff ???

I want to learn too.

Where does your electronic knowledge comes from?

[seanreynoldscs]

@qrrak Concordia University: Computer Science, Physics and Mathematics

Washington University saint louis: Masters of Computer Science

and I learned alot from a little company in London named BBA-reman.

other than that... all the arduino stuff is self taught.

[dorin92]

Cool man , i'm traiyng to do these but i know how to conect the helicopter to PC.

[seanreynoldscs]

Well; fortunately for me, these dont usually spontaneously break apart :)

Usually they have to crash before the blades start flying into fences.

I engineered the bricks make sure that it doesnt get a chance to wreck.

But yeah, I think if a wooden blade is flying at my head I have larger concerns than my eyes :) These blades will prob break goggles... so I will have to make sure it doesnt wreck in my room while I'm sitting next to it hugh... :)

[aquatherapy1]

yep your blade need tracking fella.

[jasmine2501]

There is a huge safety problem here... please be more careful. The blades on this heli are capable of 220mph, which you should know if you are capable of building the thing you demonstrated.

Also - you just demonstrated a ridiculously large version of something that is already commercially available and is about the size of a a pop bottle lid... why not just get a simple flybarless stabilizer system?

[arsenix2001]

"The blades on this heli are capable of 220mph, which you should know if you are capable of building the thing you demonstrated."

LOL

[jasmine2501]

Don't lol - do the math, it's true. 3000rpm and they are 335mm long.

Didn't mean to knock the invention - it's cool to be able to build that yourself.

[arsenix2001]

Im not laughing at your calculation, I know its true, the fact he was smart enough to build this but dumb enough to sit 18 inches away from it with out even saftey glasses is what was amusing.

[jasmine2501]

I'm considering wearing glasses and a helmet when I fly actually. I nearly hit myself one day with my Blade 400 - and I did take out part of a fence with it. It cracked the fuck out of the fence and totally destroyed itself, in a matter of maybe half a second.

[arsenix2001]

Believe you me, I understand... I almost took off my head a few weeks ago, ducked, lost control and it exploded on a flagstone patio! We should invent a "pope bubble" or something for operating these things close range.

[vanepico]

You feel good with yourself when you are able to build your own thing when everyone else just buys something, and this will be a heck of a lot cheaper...

[EmbeddedPhysicist]

Buy some XBees from sparkfun so you don't have those wires all over the place. Other than that it looks great!

[tnick2]

electronics + copter = $1000

safety glasses/goggles = $3

eye surgeory = priceless

[MattEvans16]

nice blade movement

[traxonja]

watch your neck :)

[JRproducts]

Looks like you need to track the blades. Very cool.

[joshatkins94]

Neat!
