Your english is terrific, explanations are fine. Been watching and subscribed to your channel since the early tests with the flying hovercraft. Great job with these projects and I love your videos. You are a very humble man with very good achievements. Thanks for the videos. Would love to see a long distance high flight (>= 30m) in the hovercraft.
Two important points: 1. That thing really scoots! 2. Your neighbors probably think you are completely nuts and stay as far away from you as possible. I'd say mission accomplished!
I've seen you before and it took a moment to remember I had linked your Flying Chair video to my facebook wall. I just did the same with this current video. I am Danish but live in Canada and find that even though I was raised here, there are still cultural differences, so I feel at home when I watch Europeans redefining 'Inventiveness'. This time I subscribed to your channel and eagerly wait for more projects come from that amazing mind of yours. Here, we call that type of turning 'Skid Steering'. I wondered why you cannot turn while driving, instead of stopping for every turn..?
Thats my guess as well. Although, the small amount of water being accelerated will be accelerated in the right direction (backwards) since the wheels will be "standing" ON the water rather than being mostly submerged in it like the Sherp. So still a little bit of hope there. The giant surface and low weight of the vehicle will make crossing water a windy day a no-go for obvious reasons though...
Your vacuum cleaner motor oscillation is caused by something called a hysteresis loop. In order to fix it you need to add a delay between the input sensor and the power output. Usually a fairly meaty capacitor across the gate of your output power transistor should fix it.
This is like an extreme version of the Sherp, I love it! I bet it would drive right over water. You could sell these to lake resorts, I know people would rent them to drive around on the water.
I built a few models to test 4-wheeled tank steering for RobotWars, and found that it worked much better when the wheel-base was about twice as wide as it was long. That way the wheels don't have to slide sideways as much when you turn. However it looks like you might struggle to make your car either shorter (because the tires are already close) or wider, unless you move your neighbour's mailbox!
I think you are absolutely right wheel base-lenght wise, but just as you pointed out ; there is just too many mailboxes in the world for that approach in this context...:-D
if the axle widths were different (front axle not as wide as the back, for example) you could overlap the tires and make the distance between the axles shorter. probably not these tires, but maybe with thinner ones. of course then you'd have even less visibility for steering...
The oscillation your experiencing in your tires when you turn is somewhat akin to what's called "tire shake" in top fuel dragsters. As you've discovered already, it's related to grip level between the contact patch of the tire and the surface. In essence the tire kinda "wads" up on itself and then springs back into an oscillation. I think there are 2 ways they deal with it. One way, is tire pressure. More pressure makes the tire firmer and at the same time reduces contact patch and grip. Perhaps you could incorporate a system that would dynamically regulate the inflation pressure in you tires either based on the surface your on and it's grip level or perhaps simply increasing the pressure whenever you are maneuvering the vehicle. They also deal with it by controlling the application of torque and wheel speed by adjusting how much the clutch slips. Usually when dragsters experience the problem is when track conditions are tight and there is a lot of grip. Under those condition they want the application of torque to be much more aggressive to get the tire to slip enough and maintain a high enough wheel speed to prevent the wadding up of the tire and having it go into tire shake. Of course they have much more horsepower to play with. But some of the same principles might be applicable in your situation. Also If you watch a slow motion video of a top fuel dragster on a successful run (successful meaning no severe loss of traction or tire shake), you'll notice that there appears to be some sort of a standing wave that develops around the tire. You can see this in the distortion of the tire. Now, I am not a crew chief or expert on top fuel dragsters, but my guess is there is some sort of a formula or relationship between grip level, tire pressure, and wheel speed where the oscillation of the flexing of the tire at the contact patch is producing a standing wave rather than the non-standing wave that induces tire shake.
Amazing vehicle. Have you considered turning it into a wheeled stretcher controlled by a first responder walking alongside. Could you add a pitch and roll sensor to the vacuums to keep the body level on inclined topography?
This has an amazing potential to change the world for extremely cheap and portable. There will definitely be more of these appearing in the future. Keep up the madness love you vids 👍
You just need pivot steering for the front wheels, but it would be cool to keep the tank steering too in combo. Like handle bars but with speed control on each grip.
@@amazingdiyprojects Do you think something like an accelerator pedal and steering wheel/bar that determines the proportion to each side would work? Perhaps even some electronic braking on one side. Although, a rack and pinion steering system would probably reduce tire wear.
@@amazingdiyprojects Having independent controls for both would be a good idea, but you could also go one step further and have a small computer or micro-controller that could decide when to implement each separately or combine the 2. When the vehicle is stationary or at very little velocity the tank steering could be utilized. At higher speed pivoting wheel steering could be utilized.
Consider adding an emergency charging circuit that charges the batteries to ~4V per cell (So as to eliminate the immediate risk of overcharging some cells) So if you happen to take it out longer than intended, you can recharge the batteries to some extent from a nearby power source :) At first thought, some type of rectified mains then a SMPS or high voltage buck converter would be sufficient to limit the current
Amazing creation... as always. If this was a Top Gear episode, when you've bumped into the bush, Jeremy Clarkson would have shouted: "Power... power!!!" :-)
Seeing this reminded me of an idea I had decades ago. Back in the 1980's the motor sport of mud bogging was very popular. It's racing through long pits filled with mud. The vehicles that competed were usually 4 wheel drive, large, had very powerful, noisy engines. In spite of the power they had, most would get stuck and not make it all the way through the pit. I thought the problem had more to do with flotation than power, and thought it would be incredibly funny to make a pedal powered vehicle with 4 wheels that were all driven from the pedals. I figured on using large tractor inner tubes for tires with a bit of canvas on the outside edges to provide a bit more resistance to puncturing. I thought it would be easiest to have it steer by articulating in the middle. Sadly, I never did build it.
@@theupscriber65 I'm sorry that you didn't make one of those too. The world would love to have one. I suppose that we don't have a hovering skate board because it's beyond the ability of current technology, and possibly defies the laws of physics. What I was thinking of making was technically possible, just beyond my budget at the time. This video reminded me of that idea, I hadn't thought about it in years.
Awesome, I should know better than to underestimate you, however this turned out much better than my expectations! Forgive me. Thanks for sharing, congrats on a way cool build!
The tire size and wheel base reminds me of the popular monster trucks here in the United States. All you need now is an inflatable body. We had full size inflatable rubber tanks during WW2 also.
How to solve the steering problem. Since you're blowing air into the wheels through the axles, you'd need a way to have flexible but airtight joints. Simple solution is pieces of universal corrugated radiator hose. Any auto parts store should have some in various diameters. You'd also have to construct a rigid hinge around the hose.
Kudos to you! for protecting the seams you might wanna use this new type of undercoat for cars, they also use it as bedliner, it's some sort of spray on rubber, the can says it's kauchuk based (sorry if I spelt that wrong), it is very tough, but elastic when it dries, and quite wear resistant. You might want to coat the entire running surface with it for wear resistance, but I'd test it first because it might make the tires too grippy, which seems to be the main problem already.
Thank you for doing this in English I absolutely enjoy your videos! Most people that speak English here in the states only speak one language you sir have one up on us.
I think a wraparound tread covering the contact surface between tire and ground might help against the grip bounce problem while adding puncture protection.
You know, thinking about it, a vehicle like this could have really good use for Search & Rescue in arctic regions. Some one's missing? "Oh yeah, back in the shed we've got five inflatable vehicles packed away that are great for driving on glaciers! Let's go find those people!"
Thanks! Yeah, Im having a great time playing around with this tech! Im especially fond of the"Alice in wonder land"-feeling I get when walking around, standing next to and riding the vehicle :-D
The work you do with limited tools is incredible but is there any reason you don’t have the front axle actually turn for steering? The turning radius would be greatly reduced but the material may wear better. You wouldn’t even need a steering wheel, you could just have foot straps and control the front end with your feet😂. I really like your work keep it up!
@@amazingdiyprojects If your going to add steering, why not 4 wheel steering? Are all 4 wheels independently driven? If so 4 wheel steering should be not much more difficult than 2 wheel. Also, I don't see any reason you couldn't use a combination of both 4 wheel steering and your differential steering. Another idea, if you dynamically regulate tire pressure, would be to Increase tire pressure in the wheels on the outside of the turning radius while lowering pressure in the wheels on the inside of the radius. This would work like "tire stagger" which is often used in oval track racing.
I've seen tank-like systems that work more on differential braking rather than throttle, like a Sherp. If you had a controller with feedback from each wheel, that was capable of either "locking" or reversing individual wheels I think that would make for the easiest turning.
Some type of limited slip differential is needed, as you leave your house onto the road it's possible to see the forces being applied to your rear wheels as you turn and straighten, maybe too overpowering for the materials to handle. Must have been amazing driving down your street in that machine.
@@amazingdiyprojects fantastic! can't wait too see your solution. I really enjoy watching you overcome the technical problems you encounter, it's incredibly vicarious, thanks for sharing your awesome ideas. I used to do some off roading in a 4wd and changing the tyre pressure can alter grip depending on the surface you're driving on, possibly having a lower tyre pressure may help turning on grass.
Awesome! How about an articulated frame steering to maintain the simple straight axels and get a more precise control at speed than possible with the skid-steer setup?
Interesting wheels. The real stress seems to be located in the center around the wheel hubs. Perhaps reducing the wheel's grip is all you need to reduce damaging oscillations that may cause the wheels to rip.
When will you do your first water crossing with this contraption? Also, you should not try and turn when stopped because the side forces on your hubs will be large.
It seems like the tire contact patch is too big once you climb on board. Can you run a higher pressure? It might help with the steering characteristics.
This would make a great mars rover, you could deflate it to fit in the rocket payload and inflate it with mars atmosphere when you arrive. The big wheels are probably good for the rough terrain too.
Awesome! Yes, definitely need some form of fine steering, perhaps a centre pivot? Visibility may be improved with transparent wheels, a jackable seat or even a periscope! :-)
@@amazingdiyprojects hehe.. a submarine style periscope would be amusing... but realistically you could take a Mars rover approach using twin cameras on a servo operated pole and head-tracking FPV goggles - I'm sure you could try something like this successfully, though static wide-angle cameras for front and back with a monitor screen would be much easier and cheaper. Just one problem with a centre pivot is the change in centre of mass which could lead to tipping, though the small gap between front and rear tyres won't allow that to happen. Any changes in CoG will be more pronounced on water, so bear that in mind too! May end up being better to have 1 or 2 pivots on the axles instead.
Manuel Pellizzari id imagine if he did that then it would be more likely to have the wheels pop whereas with more weight distribution they are slightly more rugged. It would help the steering though but it wouldn’t be worth the trade off. An better solution may be to work out a sort of “differential” like in a car or to have the front end actually steer.
Andy Lee Robinson yea I put it in quotations because I meant something that does the same as a differential so the wheels don’t have to spin out but in your defense it was kinda confusing
amazingdiyprojects I can’t see driving while standing to be very safe. Lol. Thanks for replying. I love your builds and your attention to detail. Can’t wait to see what you do next.
You might be right. This system gives me a certain degree of fail safe, it will be able to fight both wear and tear degradation over time as well as minor punctures as well. But certainly on the low efficiency side. Think bouncy castle.
That thing is so awesome, I follow the build on and off is it not supposed to be able to drive on water? when do you do the water testing? driving on water goddammit😁😁
If the incline is wet grass, I would be very surprised if I could not go up pretty steep hills/ obstacles, but lets just wait and see how the vehicles terrain characteristics unfold. :-)
if the driving position was prone (laying down), with a harness this vehicle would be like the cars in Rollcage or Grip, where you could flip over and still be able to drive !!!
that snow slip just means that it will not climb in snow, and probably wont be able to stop on descent but its great for miles of flat tundra I guess a brilliant and unique project though
It only "slips" on ice/snow when the motors apply allot of power against each other. Acceleration on snow is not bad at all, so I would guess that it could climb pretty steep on inclines covered in snow. Ice would for obvious reasons be more difficult.....
For my kyosho blizzard pisten bully I use a 3 dollar v-tail mixer for a rc plane together with two simple electronic speed controllers. Works perfect for me. In your case you must make sure it is not possible to instantly change from forward to reverse with the rc transmitter. And instead of a rc transmitter and receiver you can also use 2 dollar servo testers.
A want to make something similar, but i think i will use the ring inside the tractor tire. much easyer to fill, and airtight. small kinese 125 4T and have steering like a frontloader (joint in middle.) sry bad english
This is awesome! I wanna see you drive over water next!
The fact that he never replied to this comment blows my mind lol

@@amazingdiyprojects Maybe a netting around the wheels for water driving is a solution? like snow chains on car tires.
Оn the water this car will be a toy of the wind. For strong wind on the ground too.
@@RW3DQQ You would have to choose a calm day, and a small, preferable shallow lake. of cousre.
@@amazingdiyprojects You are going to need to think about water traction. Paddles for the wheels that double as tire tread perhaps.
Great progress with the machine. Your English is perfect (better than many native English speakers in fact).

In order to fix it you need to add a delay between the input sensor and the power output.

For the differential, create a mechanism that allows the faster wheel to ratchet forward. Search "lunchbox locker"
I think a wraparound tread covering the contact surface between tire and ground might help against the grip bounce problem while adding puncture protection.
Wrap tires in kevlar to make it more puncture resistance and it should keep the weight down.
Its coming along great. Well done!

You need a pivot point and stear with your legs. Independent torsion pivot with spring front to back, so you can have bend from to back.wheels.
It will be interesting to see what type of steering you choose. Obviously, each type of steering mechanisms will add more weight to the vehicle.

What transistor are you using? The one you held up at 5:20.
You just invented the next Mars Rover ☄️🔧⚒ What about treadmill belts laced on? Awesome 👏
Put some treads on the tires. Maybe cut some rubber floor mats, or more fun would be a bunch sneaker treads. Just a thought.
Perfect for those 2ft snow storms. Drive on top of the snow.

What makes those wheels turn if I may ask?
Awesome!

For driving vision limitations... Maybe ad an Ariel GoPro camera ? And a monitor so you can see in your blind spot areas?

OMG MATE! - I want one of these!!! :-)
Awesome Job!
Drives down the road, hits a nail and takes off like someone just released a balloon.
great medical rescue possibilitys!
is possible to seat and the star the inflating proses?
I think having it bend in the middle like a payloader is your best bet for steering unless you can steer with differential inflation levels.
Wouldn’t an air tank and top up electric compressor be better and more energy efficient than using the vacuum cleaners?
You might be right. This system gives me a certain degree of fail safe, it will be able to fight both wear and tear degradation over time as well as minor punctures as well. But certainly on the low efficiency side. Think bouncy castle.
Now the question is would it be able to work on water?
That thing is so awesome, I follow the build on and off is it not supposed to be able to drive on water? when do you do the water testing? driving on water goddammit😁😁
What about traction on inclines? Be next to Zero with thosr wheels
If the incline is wet grass, I would be very surprised if I could not go up pretty steep hills/ obstacles, but lets just wait and see how the vehicles terrain characteristics unfold. :-)
How did u make the tires !!!!!
que lugar lindo esse que você mora, onde é ? abraços
Looks like it would be fun on water.
if the driving position was prone (laying down), with a harness this vehicle would be like the cars in Rollcage or Grip, where you could flip over and still be able to drive !!!
that snow slip just means that it will not climb in snow, and probably wont be able to stop on descent but its great for miles of flat tundra I guess
a brilliant and unique project though
It only "slips" on ice/snow when the motors apply allot of power against each other. Acceleration on snow is not bad at all, so I would guess that it could climb pretty steep on inclines covered in snow. Ice would for obvious reasons be more difficult.....
any lakes nearby to test it going over water?
Here it is, the first test in water!

For my kyosho blizzard pisten bully I use a 3 dollar v-tail mixer for a rc plane together with two simple electronic speed controllers. Works perfect for me. In your case you must make sure it is not possible to instantly change from forward to reverse with the rc transmitter. And instead of a rc transmitter and receiver you can also use 2 dollar servo testers.
So... Nice!
Good luck!
A want to make something similar, but i think i will use the ring inside the tractor tire. much easyer to fill, and airtight.
small kinese 125 4T and have steering like a frontloader (joint in middle.) sry bad english
That would be a great inflatable float for a parade....
Just need an inflatable body....
Are you going to take this on the (liquid) water, sometime?
Where are you located? You sound swedish or scandanvia
