Colin Furze Helped me test my TANK

there we are, take it, remember when Colin F built the rhino

tank

and then got stuck in a ditch and had to be pulled out with a JCB? Elides pioneered the concept in the 1950s, the idea was that, due to the domed wheels, the deeper you sink into the mud, the more grip it has. Colin converted a dump truck to build his version of the Rhino, but it originally had much smaller wheels, the motors are hydraulic, but there wasn't enough talk to turn the larger diameter wheels. when it was necessary due to the increased leverage, my plan is to make a slightly smaller version and it will be electric and I will try to get a big reduction from the motors to the wheels so I can get more relative torque.

It will also have a servo control tilt angle so it can transform. I'm making my wheels out of flat sheet material, which is the same way Colin did it, other than mine they're made out of plywood, which is a pretty good material to use because it's really easy. to get it and it's very easy to cut and I don't have to make massive things out of heavy steel, it will also be lighter so we have a lot of pieces to make here, we have a lot of these circular pieces and then we have a lot of quarter pieces to put all the fins on the wheels.

I cut a huge htd profile pulley that will fit the wheel and the belt will go as close to the circumference of the wheel as possible to apply the most leverage and I have this little shim that goes on the outside to keep the belt from falling off , unlike Collins. I'm going to leave my wheels wide open instead of filling all of those segments with a sheet. and I'm hoping that that will give it more grip and also it won't fill up with water that I'll have to drain somehow, so I'm basically putting this edge strip on some kind of plywood edge to make it stronger and hopefully that should really be and will really

test

the grip principle of these wheels.

There are four but they don't fit on the table. Now we are going to use the metal to make the chassis. It's time to cut some. lengths of steel, so I set up this jig with a block clamp on the bench so I could get all the pieces exactly the right length. This is a multi-material blade that will cut all kinds of things, including aluminum and steel, so no problems there. there we just deburr the edges to remove all those rough bits and then we have a collection of metal parts, oh, that brings me to a joint like this and also this one, which is the middle joint of the whole vehicle.

I love metal, but now it's time to use something plastic. I'm printing some pretty large parts here with a 1.2mm nozzle and these will be the main articulation points for the tilt angle. You have already seen this part, which is the bearing support. the end of that wheel, these parts are bushings that fit into those first parts so we can move that camber angle out, there's no bearing because it's not really high RPM, just a quick announcement from my 3D printing sponsor thanks to the announcement LOL for supporting my channel with 3D Printers, it makes it much easier to get all the projects done on time when I have so many printers to print in parallel thanks to the 3D fuel for the filament for this project.

Now you can get 10% off at 3D fuel.com. with my special code and Link and I will get a small commission, those 3D printed bushings fit on the end of my square axles and the round axles can then be rotated with that protruding piece that will have the motor mounted. I love it. the feel of solid metal joined to solid plastic, now we can put the whole chassis together, so it's chassis time. Yes, as a matter of fact, I put those bushings in the wrong place. I was supposed to leave one piece sticking out so everything was the right length, so I had to do that.

Unscrew them and move them, but it doesn't matter, now we have the ability to move those axles and let them vary the tilt angle on both so that they move freely with those bushings in their plastic holes, but it can also rotate all over the place. At the moment, we need some kind of actuator to control it and keep everything in place. Yes, they are some big linear actuators from Gimson Robotics. These are quite fast, at 40mm per second and exert around 75kg of force, which is 7 150 Newton M, they are actually quite fast compared to most linear actuators, so they will be absolutely perfect for moving that angle of inclination in and out, so now the chassis can be folded in the middle so that everything can turn like the Collins version, but also one.

One side can tilt and that means all four wheels must stay on the ground so they don't end up on the ground and one spins in the air. I have bearings in all my wheels, so thanks to Simply Bearings for the bearings for this check. Just bearings. co.uk, it's time to install some motors to drive the wheels and those are going to use these drive belts. Yes, we are going to use transmissions. These are Drive brand motors which are 8325ss, they are 100KV and quite Pokey, we are using the O Drive S1 which is a relatively new style controller, there is a magnet on the back of the motor and an encoder built into the plate to fit directly on the back, there is a kit that comes with everything. of the brackets, assembling them all we can see that we have that sandwich plate on the back, we can use the O Drive guey which is now web based, as opposed to the old text tool that you had to use to configure that motor and calibrate it and also check and

test

it to be plugged in with USBC.

The motor runs quite well even on its own. You can see it wants to tip over and I could tip it over if I really did what I wanted with it, but we. I have quite a bit of power, about 1500 motor watts, so I have them all mounted on those red 3D prints that you saw and I have a T5 pulley installed on the front, on the bottom. a piece of aluminum and there is a hole to mount it to that 50/25 steel, so we have a front piece that goes, there are two pieces of bolts screwed in there, one piece is going to support the T5 pulley so that you don't just cut it off and the another one is going to support an intermediate gear to drive the wheel so it has a T5 pulley on the bottom and a smaller hd8 profile on the top and it has bearings on each side, like a skateboard wheel, just like me.

Turning the motor, of course, turns that big pulley and that turns the smaller pulley that is going to drive the wheel. I also put guide wheels on each side to tension the T5 belt, but before we continue with assembly, it's time. for a quick announcement from the video sponsor which is pvk now PV case is a next generation AutoCAD based photovoltaic software focused on automation and precision. It allows you to simulate the actual location of a solar plant from the early planning stages by incorporating 3D topography. data points, making PV Case the ideal choice for companies undertaking large commercial and industrial projects, as well as utility-scale plans.

The software is really intuitive and streamlines processes to help reduce the learning curve and improve productivity. Duties include everything from electrical design to the prototype stage. shading and terrain analysis and automatic generation of construction documentation so that the PB case truly allows engineers and designers to take the project from its initial conception to the procurement phase. This is truly an end-to-end approach that saves time and reduces errors. It is optimized so you do not need to switch between tools or other software platforms. Other features include slope analysis, piles and collision analysis. Automated 3D survey cabling. Design comparison. parallel and quick preparation of buildings in 3D try the PPK for free by following the link in the description of this video so that it fits on that 5025 steel and can be moved up and down to tension the belt that will go down to the wheel, so that there's that intermediate pulley and obviously as we lift it up, it's going to tension that bottom part. belt to fit all those studs and I have these little shims that I made exactly the right size and pushed in so we can tension the HTT belts to prevent any possible belt slippage on both the T5 and T5. on the hd8 and it looks pretty tight as you can see there so I don't think there's going to be any problem with those big thick pulleys.

Let's turn one of these on so we can use the O Drive tool to control it. they're about 100 to one and the motor makes about 60 to 70 turns or revolutions per second so we should have a lot of torque and I also have the ability to stop and start those wheels and reverse them and we're using the regeneration basically to recharge the battery to get rid of all that energy, so it seems to work pretty reliably and I think it'll be fine, so we've got that belt that you can see slightly rubbing against the wheel. I need to move that wheel. its shaft so I can fine-tune the belt position, but otherwise I'm pretty happy with how it's going and that motor is currently moving at top speed.

The rest of the electronics for this project looks like this, which is 4 bts7960 motor controllers that are working. to control all those linear actuators a radio control receiver and also a Tec 4.1 and I have used that because it has a built in Can bus so you need the external Cann bus transceiver which is that little extra board but that means I can daisy chain all the O units, so I have all the batteries in the middle and we're going to run this with about 50 volts and then the electronics just go in the middle and this is all on top. so no water gets in basically when we go through the ditch that's my power distribution but there is a cover to cover that because 50 volts is pretty dangerous all my actuators connect to these connectors that were provided and I'm using xlrs to connect daisy chain the canbus between all the O units.

I just have to remember to keep all those connectors up and zip tie them or something so they are out of the water so the canbus and ground go into each one. from the O units and that gray wire is a shielded wire so we shouldn't have any problems with interference and as usual I'll use my universal remote that I made in another project to control this which is a DSM remote, so yeah it's pretty Pokey, it's probably faster than it needs to be because it's a crawler and not a race car and the steering right now just spins the outside wheels faster so it basically has no steering actuator active, it's a little tricky to drive in my kitchen so it's time to pack it up in the van and we're off to break dancing city 2 Electric Bo Glo to try it out with a very special person TR, perfect for this to be as cool as was.

It didn't really work very well, it was unstable and underpowered, but it showed promise and James obviously saw that promise and developed his own, so it will work better than this or all of these problems included in the design and therefore the Rhino is always running. It's a strange machine that looks cool but doesn't actually work very well, we'll see where we are. Take it away J, so we have four-wheel steering and all of these units are still speed controlled, so they should work. at exactly the same speed you should be going in a straight line, but if we don't have any active steering then all we really have is the ability to move the wheels one way a little faster, I mean I don't think that's a problem .

I mean, obviously, you have like a hydraulic ram that articulates it, but the whole time it was failing, I never thought that the steering wasn't very good, oh yeah, so I don't think you have anything to worry about that and I have seen you. We have these linear actuators so you can give it what we can, yeah we can transform it to get it into proper Rhino mode so we can run around the edges, we don't have any real grips on the wheels, it's all a smooth strip of edges, yeah, other than that we have I have these edges that are like the griffy part, so all the wheels are at the same speed.

Now I'm going to try to turn by moving left and right a little faster. That doesn't work too bad. I can't get out of there. If that helps, yes, it's a little bumpier, but oh yeah, those wheels feel a little better if I go slower, yeah, which is what it's supposed to do, obviously, I'm not supposed to drive again on the tires. You see the wheels slipping on the grass if we go. slow it's a

tank

it's not a racing car so no yeah driving is fine if I go very slow and careful with the wheels in this mode so we actually have some chance of grip instead of this soft edge on the wet grass. so it's not a racing car, if I go very slow it's okay and if I'm very careful with the steering, so turn very carefully andcome out of the curve and then go straight back, don't bend, oh this.

This better be grippy, isn't it in that slightly sticky mud? The test passed no, I don't like you going the other way, please, I would like you to go down there. I probably should have had some active activity. Steering, I was going to say as soon as the wheel slips then I can't drive anymore, the old mid-jointed Ram is starting to look pretty good, now I'll get there eventually, there we go, depends on how smooth. the ground is if the ground is soft on three wheels and slippery on the other then the other wheel just bends in half anyway here we go it finally did it the wheel works I think I see it's sliding everywhere, wow!

It was, uh, you see, I can't even understand what's what, from that I understood that the original idea of ​​the design was that, the more they sank technically, the wider they became correct, you can imagine. how I felt now sa in the mine on this wobbly hill roll over you didn't roll over I almost did it a couple of times God, that's the spinning hoop if anything needed to be a little more, yeah, a little better than it was. Those wheels are going to spin, it looks great, it's jumping through some bushes. I don't think the video is called fixing Colin FS, his biggest mistake.

It will be called cool, think the same way. I have learned from your mistakes. Colin and I've repeated them exactly right, I've said enough, it's just that there is too much wheel slip. I think we're going to get them like you said. They put straps around the steering so it can't oversteer. The engines are super powerful, like yes. I have no problem with going straight, so I'm fine. I just can't turn, which is a different problem than the one you had. Yes, I could stare. I just didn't have any conversations. Come before the camera. Oh I'm sorry.

I'm filming your hands, oh Goin, I think we do both. I think it's a hybrid of all the solutions. Yes, I can still do better. At least it handles better. It doesn't spin when I don't want it to. The wheel keeps spinning. Oh, there we go, we're going down the road I don't want to go again Oh, wait a minute, what we haven't done, yeah, oh yeah, I forgot, okay, let's try that now, look at that look, well, see that quite competent look. so yes, it's the grass, GP helps him I think he's fine, look, yes, he looks quite competent here, he goes on, up, go, that's better, he says, he goes, he went up a hill, he did it and he went up a hill, which I know.

I definitely wouldn't have gotten up, so you managed to climb a hill, tick, hooray, let's try the ditch now, when I went through this, it wasn't that deep in the water, in fact it barely had any water in it. I don't think so, of course. Yeah, okay, as you can see, that's a lot deeper now, yeah, that's what we were made for, getting through the mud, so I made sure that my Can bus connectors and all the actuator motors, all the O units and all the electronic components were high. sticks, that's why it looks like this, so let's go in here, which we think isn't as deep as my Wellington anyway, so I'm hoping unless I roll it, God, I'm stuck here unless I roll it. roll, everything will be resolved.

It's fine, and it's quite unstable as we've seen, so I'll do it very carefully because it's a tank and not a race car. Remember, I feel like I'm driving a waterwheel, something that's pretty wide, though come on. Come on, I can't turn now, maybe I'll get there eventually, yeah, that's what happened to me. There's a lot of them that spin, they're just stuck against the bank and I can't, uh, if you're going backwards trying to do it, but you can. t steer, come on, Rhino 2, come on, make it round, oh the wheels are too wide, should I pull the front ones?

Wait a minute to do it now, here we go, come on, right, ah, you have the opposite problem, there you are. This bench, that's me, that's it, that's it, it's crawling, it's crawling, it's crawling, oh, now, this is the part I got stuck on, I was trying to get out, come on, come on, come on , come on, come on, come on, come on, wait, wait. wait, oh, you see that sight that looks like that little duck doing that thing that looks beautiful, there's a little duck there Colin, oh yeah, this is the uh, the duck of shame, he put him back in his desert, so , what reason does that one that is spinning have, yes?

So why isn't everyone else? Because they are spoken or well, they should be able to do it. They should fail if overshot, but they're all green, so I can see that one is trying to spin. please tell me your middle name starts with c why because then you would be JCB no it's not like that it's an e a at least I don't need the JCB although it's not here anyway we drag it with a quad I think so it's out Now , but you know what I mean, I mean, it's on paper, it failed just like mine did in the ditch, but I think if you had done it, if you had proper real direction, I think it would have done it, it would have come out easily. of that, yes, maybe yes, oh, it's a little lumpy, look here we go, come on, going to look at that, I don't want to submerge that or Drive In The Water, I'm not going to go in there, no, but look it's f wa who whoa who gets rid of the curvature so the motors go higher Transformers that's all you've probably gained that's oh no it's not starting wait how deep is this I'm not sure the point, I can't run After arrive, I don't want to go.

I don't want to go in there. I really don't know if I can go out now. Can we drag it? No, I'm in steamboat mode and now. I'm totally stuck, yeah, oh, I don't know, I don't know, I think Rhino 2 oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh oh ow ah, that's a nervous James Bruton seeing that I'm dead . Now, oh, is he dead? Something I think maybe I put my eyes in the water. He wasn't supposed to lean that far. I think he's fine. Jimmy B. I don't know if I can get out of here, but yeah, look. type of I'm going to get out now Colin, how am I going to get out of here without falling into the well? oh oh oh, I've done it wrong, I just don't want to go anywhere else, it's pretty um if it wouldn't be that I could just leave right?

I don't know, let's get this out now. Lower House, I'll probably have to take it out. I think we're going to have to take this out. ourselves, oh, there you go, look, that's not terrible, return to safety if it doesn't destroy a lot of O units, they are and now it's a little cleaner. I do not recommend Rhino Wheels. Do you recommend Rhino Wheels once again? It shows promise, but it shows more problems than I promise, but I say I think if it had power steering, then if the steering was forced instead of just wheel guidance, I think it definitely would have fed better in the swamp, that It's safe, yeah, you'd think they had it too. in the huge spaces, I would like you to know grip and paddle, there are people there, we are going to use trank tracks, which are now two attempts at a failed concept and we can probably say that we still failed thanks to Colin, yes, if you want to go to see my could do exactly the same but even heavier then yes.

I'm sure there will be a link somewhere in the description. Many thanks to Colin for letting me try it out, giving me a hand and showing me the original Rhino controller. He discovers the compilation of him if you haven't seen it yet or links in the description to the videos of him. In the unlikely event that you haven't seen his channel, I'll post all the cat and code for this project as I usually do. It's open source, so if you want to use some of it in your own projects, you can. If you want to support me through patreon or YouTube channel membership, patreons and YouTube channel members get all the videos up to a week early and previews and Images of what's to come and all that discussion and the benefits of Discord , okay, that's all for now.
