it was oddly satisfying to watch it slowly creep along the floor, yet it was so elegant in its movements. Like a victorian lady wearing one of those poofy dresses, she just seems to float across the floor lol
I was thinking very much along the same line, using some sort of a lift mechanism to raise it up before starting the main rotors. But I hadn't thought to put a wheel on the end of the leg. That should reduce the chance of damaging it on touchdown. I think some sort of passive omnidirectional wheel would be even better than the motorized wheel, so it can roll in any direction immediately on contact with the ground. Then design the leg so the wheel only touches the ground when the leg is fully extended, so as soon as the leg starts to fold, you become anchored in place and can turn off the main rotors safely.
Regarding vibrations, you need to measure the natural frecuencies and optimaly the mode shapes of your structure in order to know what you are dealing with, the first is quite easy with an accelerometer and some fft software, the second needs a bit more but both necesary in my opinion. Congrats, nice job, keep on!!
can you build a variable pitch quadcopter? the idea is to connect all 4 props to a single engine (potentially a gasoline engine) so that they all spin at the same rate and then control props' pitches to maneuver.
i'm not sure about the whole variable pitch apparatus. can't you reduce weight by just controlling those stabilizing motors' rpms? besides, can you use 3 instead of 4 in a Δ-shape? or do you need yaw torque and the ability to quickly change thrust direction?
One idea leads to ten new ones! Thinking ahead to the possibility of a scaled-up version, what would happen if one of the two main rotors failed, is a controlled landing possible?
That is a single point failure part of the craft.The two rotors would be interconnected via a shaft. 3 or 4 motors feeds into that shaft via one way bearings. The system is one motor failsafe, but if the shaft or final reduction gearbox/propeller fails you will fall, or flip If you turn off the main motors there is a chance that you will fall perfectly vertical, which might be something you could exploit safety wise.
I was thinking about the wheel. How about a ball? Gonna be kinda tough designing it to get a wheel that would turn in any direction but what the heck. Also had the idea of a no air tire. That would be lighter and what the heck you don't need air in the tires or millage out of them.
Yes, I have been contemplating a single large (free to spin) yoga-ball. If the ball is large enough the craft might get to be amphibian as well!?!? If the control system still is able to hold the floating vehicle upright...
@@amazingdiyprojects I think a free spinning ball would make it quite hard to move any direction, it would first need to lean over in the opposite direction and when its moving keep it in balance against the friction of the ball wheel which will vary quite a lot depending on inclination, surface, water, side-wind etc? I really like the fact of this vehicle with a one-wheel (or ball wheel) that the stabilizing functions are active before the vehicle gets airborne, it seems to make it safer than VTOL-crafts that stand fixed on the ground before taking off.
I was so impressed with your construction and the way it works I had to subscribe. As far as the looks? To me it resembles a flight capable scorpion 🦂. As for the lift rod try looking into a device it appears to be hydraulic but it's totally electric and super light I had one in a mobility crane for lifting large immobile persons of the bed and in ,out of water. I was so impressed with its power and simplicity I had to have one, I can send you a picture if you like. I will donate it to your project if you can utilise it. I also liked the idea from one of the comments a wheel like track mouse ball super light plastics. No need to turn it be like an air cushion.
Amazing to see the rapid evolution of ideas! Just re-watched the initial video for this project (OTV 8) which has detail of the attitude control system... Wondering what the advantage is of using a variable pitch propeller (with the need for the servos = complexity/extra weight/more to go wrong), compared to varying the RPM of each motor to control the thrust? Also wondering if the performance of the propellers might be improved (or RPM lowered) if each was mounted in a small bell-mouth duct - which would also give protection to the propeller (and to table legs and humans! Especially the lift!!) - though the trade off would be greater area for cross winds. Comment follows from Video >> Wyman's Workshop "How to apply ducted fan theory to real world fans" ua-cam.com/video/QccRbsZVg1Y/v-deo.html
The idea of abandoning a project/design, part of way through i think is the main M.O. of anything designed to be mechanical lol. And if over a decade of work and like 4 and a half years of schooling in machining and mech. design eng. have taught me anything is, its better to put away/retire a design before you've spent too many hours and have to deal with the kick in the pants, that it is to have to swallow the defeat and start again. Either way, I love the way it kind of just seemed to float along, when it was on the wheels, and the take off was almost magical! It took off so gracefully and smoothly. Great video and cant wait to see this thing full scale. Just my $0.02 here, but i think a small version like this could make for a quite stable, yet precise sky crane thing. wouldnt be able to carry too much, but the precision with which it keeps balance, I think, would make a crane that would be easy to hold in place and very competent in manoeuvring in close quarters
This separation of pitch roll and yaw from lift is really cool. I think tricycle gear would be a good idea - some kind of "power off" protection of the props
So i was thinking, if your plan is to use a fuel engine to power the main lifting rotors, it can also power a charging system to recharge the batteries of the control system, i have been collecting parts for my own project now, on an RC scale, think i'll pick up an old G.I. Joe
I thought about having just two motors on the top, with controlable blades tilt like in the rotor of a helicopter, one motor to control back and forth balance and another left right. So both in vertical position, but one in Y axis, and another in X axis. It would be much more complicated to implement, but you would save 2 motors weight and power consumption.
very interesting to see this creative idea being developed. Although perhaps technically even more difficult to do, you could in theory replace all 4 top rotors with a single vertical cyclorotor, as is capable of providing thrust in any direction along it's circumference. it's basically a variable pitch propeller but arranged in a carousel... just a thought
Any thoughts on updating the FC? The old KK2, while cheap and easy to use is very slow and sketchy by modern standards. Joshua Bardwell has a UA-cam channel and is expert on all things flight controller if your interested in improving...
Could be safer taxiing round without having the main props running. Again pure genius sir, bravo. When you said turn the wheel so you can drive along sideways it instantly made me think about Colin Furze and his attempt at a flying bike that didn't have control, maybe you could could supply the control...? Stay safe.
Very interesting take-off and landing mechanism you described at the end there. This is what I've been most curious about. So, it'll sit on the legs you added to this version (or similar ones) and then the wheel will extend on its shaft to lift the entire craft up off the legs (and make clearance for the main lift propellers)? Am I understanding that correctly? I wonder if some sort of hydraulic mechanism would be lighter or heavier than moving via a motor.
Yes, that sound about right, I have not thought it through properly myself yet. I have to check system weight, electric vs hydraulic. Pneumatic would be spongier but might cushion hard landings.
I really love your projects and videos! I subscribe to 200+ channels and your channel is one of my absolute favorites. Your projects are so cool and interesting and I love to see how you work with problems. One thing I would like more of is more of the process.

You could get around the idea for a steerable wheel with an omnidirectional wheel, no turning required, just roll whichever way you want.

@@MoondyneJoe Watched all his vids, probably why the omnidirectional wheel was at the front of my mind.

When it first started to move I got one of those totally uncontrolled burst of laughter, not that it funny but was working and working well... cool!
it was oddly satisfying to watch it slowly creep along the floor, yet it was so elegant in its movements. Like a victorian lady wearing one of those poofy dresses, she just seems to float across the floor lol
I somehow assumed the taxiing would be performed by free-rolling wheels and using the props up top, segway-style, but this is brilliant.
Really awesome to watch the evolution of this design. Thanks for sharing!
The concept is amazing, complex and crazy!

Excited to see the large scale one :D Cool concept
I really hope you are able to take this to manned 1st flight. I love the design; it looks like an attack scorpion!
can you build a variable pitch quadcopter? the idea is to connect all 4 props to a single engine (potentially a gasoline engine) so that they all spin at the same rate and then control props' pitches to maneuver.
Just add floats and you'll cover all possible surfaces and dimensions.
😁 Looking forward for future videos. 👌
Could you incorporate your Levitator project as the vertical thrust sources?
i'm not sure about the whole variable pitch apparatus. can't you reduce weight by just controlling those stabilizing motors' rpms? besides, can you use 3 instead of 4 in a Δ-shape? or do you need yaw torque and the ability to quickly change thrust direction?
One idea leads to ten new ones! Thinking ahead to the possibility of a scaled-up version, what would happen if one of the two main rotors failed, is a controlled landing possible?
No way, it'd tumble out of control. The best thing would be to bail out and or deploy an emergency parachute to save the pilot and craft.
That is a single point failure part of the craft.The two rotors would be interconnected via a shaft. 3 or 4 motors feeds into that shaft via one way bearings. The system is one motor failsafe, but if the shaft or final reduction gearbox/propeller fails you will fall, or flip If you turn off the main motors there is a chance that you will fall perfectly vertical, which might be something you could exploit safety wise.
maybe some suspension on the wheels for a softer touchdown?
Do you think offsetting of height position opposite axis on the tower would provide more stability due to less propeller wash?
Amazing platform btw!
Great & very interesting!!

It looks like a roomba to remove feet from ankles.
I'm really enjoying this project, looking forward to seeing you up in the air, i'm sure it crossed my mind 10 times at work today .
Wouldn't it make sense to angle the stabilizing rotors slightly down, so they would contribute with the overall thrust?
wouldn't any disturbance make it so that you go up too?
It looks like a cross between an angry scorpion and a dragonfly. Super cool.

yes but this looks cooler :D
Is there any chance to cancel the servos, and only control the speed of the 4 motors? Also rotate the 4 motors 90 degrees to push outside to control ?
Different indeed, not sure about the practical application but it is an interesting concept.
i like the extendable landing leg, the weird ideas are sometimes the best ones :)
that is officially crazy =) The good kind!

Very cool. Quick question: what brand are those variable pitch prop mechanisms?
Do you still have your pulse jets?
Why don't you try a chassis on a direct drive wheel? You can take ready-made from a hoverboard, e-scooter or EUC.
another amazing project, congrats, great job!!! 👍😎💪
Amazing project as per the channel name! Have you named this contraption yet? With that tail it must be a "🦂"
