Colin Furze Helped me test my TANK

AD: Go to: pvcase.com/JamesBruton try PVcase for free!
Do you remember when Colin Furze built the Rhino tank and then got stuck in a ditch and had to pull it out with a JCB?
The concept was pioneered by Elie Aghnides on the 1950s. The idea being that due to the domed-shaped wheels, the more your sink into mud, the more grip it has.
Colin Furze converted a dumper truck to build his version of the Rhino, but it originally had much smaller wheels. The motors are hydraulic, but there wasn’t enough torque to turn the bigger diameter wheels when it was really needed due to the increased leverage.
My plan is to make a slightly smaller version, and it’ll be electric, and I’ll try to get a large reduction from the motors to the wheels so I can get more relative torque. I’m also going to have a servo controlled camber angle so it can transform.

Teeth on the edges

[@hansdietrich1496]

I guess one problem is, that on the wheels, even when spread out, you have a lot of ground pressure on the "bars". Only one bar at a time is touching the ground. I'd try some kind of net or fixed track in between those bars. Like on some tractors, designed for low pressure on the ground.

[@geesehoward700]

dont tanks have tracks not wheels?

[@hansdietrich1496]

@@geesehoward700Yes. I don't talk about putting tracks covering the distance between the wheels, I mean the track covering the big gaps ON the wheel.

[@poopbutt238]

Could also put something inflatable in the gaps, like rubber bladders with about 10psi in them.

[@hansdietrich1496]

@@poopbutt238True, but they'd also need grip on the outside. So putting a net all around each wheel would make sense.

[@stephensaines7100]

I agree with your observation, but not how to address it. Even simple 'teeth' added to the wheel webs/struts to all but the non-cambered driving edges would work wonders. What might happen with webbing is the web actually exacerbating the slip by getting caught in the surface it runs on. On smooth asphalt/concrete, I could see it adding traction. On soil, it could snag very easily.

[@TheRealAlpha2]

Such a power coupling. Even if it was a "failure" it's still fun seeing you two work together.

The most impressive thing about James's work is that all of his 3D printed and CNC'd parts fit together so well

[@SP4CEBAR]

I like that James is so experienced that he can make devices like this relatively quickly

[@TheDevilWAH]

I remember James starting out, his channel really shows how as you gain experince by trying and failing, your skills develope quickly. I often notice him now almost skipping over parts of the project as though they are to "simple" to be worth mentioning, that in a past project he struggles to undersand and get it working. James understanding of kinematics is a good example of this, it consistently developed over the years with each project untill it has become another tool in his belt.

[@therealchriscunningham]

[@Eidolon1andOnly]

Dome the wheels and fill in the hollow space with spray foam insulation. It'll add byuoancy, there'll be no empty void that'll fill with water in need of draining, and prevent the paddles from digging down into the water and mud.

[@jamesjacoby]

Pretty soon we’ll loop back around to inflatable rubber tires 😂

[@ColinWatters]

+1 I thought the whole idea was to use the wheels as floats.

[@Onio_Saiyan]

I like seeing two makers with different skill sets try to make the same or similar things. This scratched that itch wonderfully.

[@YellowPinkie]

As proof of concept that’s brilliant. Some steering authority and waterproofing (splashing will always be a risk) and that would be a workable solution.

[@ExiledSenpai]

I would like a video where you try to iterate upon this design and improve it. You could: -Add steering -Put a limiter on the roll -Space the front and back a little further apart so the wheels don't hit each other on a tight turn -Add some buoyancy so it can work like a paddle boat (but don't forget to distribute the weight properly so it doesn't tip) -Anything else a civilian such as my self didn't think of

[@goosenotmaverick1156]

Some filler in the wheels to spread out ground pressure would be helpful in the mud and grass,

[@ExiledSenpai]

@@goosenotmaverick1156Even better if that filler is a highly buoyant material; perhaps some sort of foam.

[@davidbenton5393]

Oh and you should lower the cg and make it heavier that should help with the slippage some

[@adadinthelifeofacyclist]

The circumference of your wheels is different across the width of the tyre, effectively giving a different circumferential speed across the tyre's width. So you automatically lose any static friction and the faster- and slower-moving parts of the circumference will be pushing against each other. There won't be any linear propulsion from a completely submerged wheel unless it is on the bottom. It's beautiful 😃

[@westoncraig]

the design work involved..superb! well done on your continued excellent projects

[@SP4CEBAR]

I like Collin's playground: he has a casual swing and a humongous anti-gravity machine

[@tomthebadasscat]

[@c.harris7823]

James, this project was one of the best exercises in experimental locomotion I've seen you do. I'm sure you learned a great deal, especially after comparing this scaled version to Colin's Rhino. Well done!

[@mhenlopotter1612]

Keep in mind this "Rhino" is only model size! If it was big enough to house a driver, it could effectively take on rocks (and water depth) 2-4 times bigger. Think of it this way: A normal curb is about the height you can expect a normal car to drive up. But a small RC car obviously can't do it. Whereas a huge minig truck can easily go over a much larger boulder. So it's not really a fair comparison when you give the same challenge to two "Rhinos" of different size. With active steering and full-size, I reckon it would do splendidly!

[@KadeStringer2.0]

Good work dude

[@nadnerb2k]

This is the most James Bruton Colin Furze project ever!! Or is it the most Colin Furze James Bruton project? The linear actuating camber is inspired 😊

[@djmips]

Lovely team-up and the unit worked well. First time full success is hard to come by! We'd all be kicking ourselves - why didn't I follow through with the idea to put in some kind of mid-pivot steering! But hey, ver 1.1 ! Nice work.

[@jonkf7548]

Let's just appreciate that Colin could have just hidden in his tunnels and ignored James or he could have just done the typical KZbinr half-arsed cross promotion but instead he went out into the cold, muddy fields with James and did all the unglamourous behind the camera work without taking over the video. Legend.

[@alfonsoPina]

you and Colin need to do some more collabs. You guys are awesome!!

[@Slye_Fox]

My suggestion would be to fill the wheels like Collin did, but slightly deeper and using a mesh instead of a solid plate. Setting them sunk in a bit more will keep the grip your getting from the edging, but also add in some extra in the softer mud without the wheels basically tuning into shovels. And using the mesh keeps them from filling with water and reduces the weight.

[@gizelle-s]

I'd love to see this run with an actuator for steering. I feel like that was it's biggest weakness

I know you probably get this all the time, but I am envious of your genius. Oh, a rhyme in one line!

[@Weaseltube]

Seems to me it would be much more effective with the dish of the wheels facing inside instead of out, to ensure a wider track and more stability. Especially as camber is added, it would lower the frame instead of raising it. But also controlled steer angle looks to be needed. Looking forward to version 2!

[@paul_devo]

Awesome project. How come you didn’t put an actuator to pivot the front and rear half for steering?

[@SavageSmithy]

Just a tip, you should bubble fillet the ends of your pockets/slots so that when you slide square boards into them you don't have to deal with the tool radiused corners interfering with the square corners of the board. Just makes things fit together much more easily

[@JCWren]

Besides the active steering, I'd think that adding some serrated metal edging to the wheels would help with grip. The rubber strips protect the plywood edging, but actually reduce grip on slippery surfaces. I envision the rubber strips staying there, and the serrated edges hanging over them.

[@ToddTalksTech]

Furniture studs in the wheel ribs for a little badger claw traction when required!

[@alanhowse9213]

More really great work it’s inspiring to see ideas been worked out looked at reimagined I’d like to see a six wheeled version with slightly bigger spacing between the wheels of Jameses version And smaller wheels on a dumper truck conversion to get over the underpowering really good program

[@mrjed]

Super cool. I think American 4x4 truck tires would be a good fix for the terrain; considering lots of vehicles get stuck in the wet English mud. They always put studs or chains around them especially in the winter if its deep enough freezing for the area. I think the loss of grip is mostly a tire tread issue.

[@anthonywilliams379]

shape wise the convex shape if anything causes a loss of grip on harder ground, it has to sink in to grip, perhaps make something like a frame that is designed to flex and crumple by a small amount to maximise contact, like letting the air out of tyres to increase grip

[@JessWLStuart]

True engineers both make and break cool stuff!

[@TheK4man]

this gonna be the new tech-tube challenge, isnt it? eventually after several prototypes, yall are gonna team up and make the big one

[@davidbandler]

21:00 One thing that might solve some issues - independently adjusting the angle of the wheels. It looks as though your wheels adjust the splay in pairs; being able to change only the one wheel - such as the wheel stuck against the bank - might have helped you.

[@tempacc9589]

Nice combo

[@ashngoyuchiha215]

when it in rhino mode, the hole in the beam make a little sad face xD

[@nikoladd]

If front and rear wheels were separately controlled that would fix a lot of the control issues. You do need it to oversteer in some of those positions, which won't happen if front wheel loses grip. In software considering you have a hall sensor, on each motor, you can program the steering (i.e. left right balance) to take into account if front and back wheels are spinning at different speeds and make a differential in software this way. Should be easy to program and test it. It could also fix the stability issue when you want to go straight. Though to account for slipping you will need some hinge sensor as well.

[@surftraveller9827]

I reckon some sort of texture on the wheel would improve the grip significantly, at time the wheels don't seem to be gripping to anything. Perhaps a bunch of tiny spikes could also do the job.

[@watahyahknow]

i agree with collin adding a linear actuator in between both sets of wheels it should be way better in getting out without trying to fold one way

[@fischX]

I have to say Colins Rino is just Epic - that thing fitted with linear actuators and remote would be a proper upgrade

[@peterjmason1980]

Would it be possible to add some form of diff/axle lock by synchronising all the motors to always drive even if one has lost traction similar to what is implemented on off road vehicles?
