This is the sort of thing where I think the new event controller blocks could REALLY shine if they were to add keyboard button press. Something like if thrust forward button pressed, accelerate wheels etc

Nice articulating suspension! That last truck platform stayed super level over the undulating surfaces

Glad to see I'm not the only one that has been working on actual suspension in space engineers lol iv been taking a crack at it for about a year or so now it's just so neat to watch the geometry in action it's also quite neat you effectively made solid axle suspension where as I made independent suspension lol keep up the great work man and hopefully we can get some insane rovers built to truly wow the SE community

I watched this and the tutorial video and for those wondering, these *do* work for their large grid variants, they just take a little fidgeting and patience to make it work. I have a line of large grid rovers that specialize in drilling that have been plagued for ages by rough terrain. These custom suspensions of yours have significantly improved their capabilities over rough terrain and I want to thank you for putting this on KZfaq. Seriously, you helped a lot Lol. 🤣

For me the main topic of studying suspentions is to find survival friendly solution to a drastic changes in weight (yeah i was building kharak like cruisers with hangars, assault and onboard production) which where supposed to atack npc's and then dissasemble, drain all power and hydrogen literally leaving only bones and skeletons. And i was sucsessfull enougth with pulling a gigant rover on Pertam out of canion, and performing its tasks. But two major sources of headic where overweight stress during contaniers being 50 % full. And inability to leave it in open. As pretty much any passing ship or spawned drone where long living enough to blow up moust of wheels or heavily damage it while operator is offline.

The stock wheel suspension is pretty good and robust in this game. You clearly enjoyed the experimentation of more complex wheel suspensions systems. I actually find driving on low gravity worlds more difficult than high gravity worlds as the suspension needs to have it's damping reduced to a very low number otherwise my rides are going to get lots of air (vacuum) when moving at some speed or rolling the vehicle. Active robotic suspensions for off road vehicles is not yet invented but already, NASA and ESA are experimenting with such suspensions systems to address the unique hazards of driving at speed in a low gravity environment. Basically, Active robotic suspension adds an additional axis or dimension to an existing active suspension system allowing it to handle offroading conditions at a higher speed than the gravity driving conditions allow

7:09 This one makes me think of a motor grader, and I could see that mechanism being handy in similar applications. Really putting the ‘engineering’ into ‘space engineers’!

Thanks for making the video. Really enjoyed it. I'm very impressed with your designs.

The last build have really nice suspension for offroad rovers. How it works in XXL, also with big blocks. And how i pull up the power to lift more, as this platform where you build it on.

Quite curious- how do you get the rotor head to attach to the wheel suspension? Never seen that before myself and any searches I've done for stuff like it before have always come up dry.

Honestly, I think the only way to make that final design work 100% forward and backwards is to use springs or another set of wheels with a rotor head (as a makeshift spring) with those main struts facing against one another. You would half the amount of wheels you could have for the same space, but it would work forward and backwards. Not sure if that tradeoff is worth it though.

Hey Quantum, Search the workshop for "Prototype Suspension Mk-15 Small Rover Frame" I think ittl be right up your alley, considering you enjoy putting rotor heads on your wheels, its my best work yet. Also the MK-14's are nice too but thats large grid. Enjoy some really crazy custom suspensions

I shared this on some other S.E. discord channels so more people can see and appreciate them!

Gosh dang thats some nice suspension

Something you may like, an idea that's been out for a good long time, is a vanilla fix for controlling sub-grids without need for a script. Not saying there's anything wrong with scripts but I encourage you to look into the "WASD Converter". I'm trying to make a biped mech with a WASD Converter built in so I won't need a script... And yes it was satisfying to see that 8-wheeler👌☺

Yes tutorial would be nice and show off large grid that would be a blast

Seems you are looking for a duel spring set up, though issue is klang as you need multiple sub grids for the suppression rods. Only way I see it to work is if pistons could be modified to be used on both ends to have them be able to compress without a script.

I think the main difference was not really the way the wheels articulated (although that had a large effect on the 1st and 2nd course), but the strength of the suspension. Especially the simple rovers were stiff as a board. Look at 2:30, the suspensions are basically not compressing at all. In order to choose the optimal (and for these tests even more importantly, consistent) suspension strength, I would do the following: (For multi-component suspension systems, you have to determine the optimal strength for each component, while keeping all remaining components as stiff as possible. I.e. first you determine the optimal strength for the suspension arm, then for the rocker axle, then for the suspension blocks.) Step 1: Put all but 2 wheels on the ground (retract 2 wheels up into the chassis using the height offset, or put all but 2 wheels up on chucks). You'd ideally do that with a diagonally opposing pair of wheels on the front-most and rear-most axles. Step 2: Adjust the strength of the remaining wheels such that both these 2 wheels just about touch the ground. Step 3: Note down that strength value. Step 4: Set the strength of all wheels back to maximum stiffness and restart at step 1 or 2 for the next component. Step 5: Set the stiffness of all components to the values that you've noted down. You should have all wheels touching the ground and all suspension components at (close to) maximum expansion. If you're not at maximum expansion, you'd need to lift the 2 wheels off the ground less in step 1.

Where the hinge attaches to the chassis, try putting a rotor between them with tuned settings. Im wondering since the hinge is limited to only up and down, allowing it to flex my help alleviate that locking your getting 9:53 mark reference

how u control wheels which are connected with rotor?

My major problem with any suspension design is the subgrid script. It never just locks the wheels. They all spin the wheels when "parked", which I can only assume is a limitation of the scripting/game itself. But it doesn't stop me from messing around with suspension designs. :-) Ninja edit: It takes a lot of fine tuning to get suspensions to move properly. Brake torque is immensely useful as are rotor limits. I usually set my minimums to keep things from smashing together, and braking torque to allow things to slowly settle. I've probably spent more time than I care to admit fiddling with them.

Can't u use timer bloks to let the hinges push down every time they get pusht up

Did you try to add a piston with hinges, in V shape, like a spring, to get additional support, in the other direction?

I did something like this a few years ago. but sometimes the small wheels for springs decide to clip through the arms and it don't work anymore.

Looks satisfying :D How about testing them with high speed or climbing those rugged teeth slope?

have you considered making the wheels slightly closer together and then adding a set of wheels at the front and back set wider and higher up? This helps reduce the chance of it ever flipping, and having wheels higher and closer to the front and back make it less likely you'll smash the front and back on particularly steep slope transitions.

Wow very very cool design :)

Would be nice it there was better control of sub grids, less PCU for rotors and hinges. One of the reasons I dont use rotors and hinges on rovers because of these issues. Would like to set up something like this though to get over the rough terrains

You have my attention. I really like trying to improve Vanilla systems

Impressive

So that rover that behaves weird when driving up to a wall has basically a torsion bar suspension (found often on tanks) maybe flipping the first two around might solve your problem

Im gonna use this as inspiration and expand upon this.

Nice video, I am new to this and tried to build something similar to the one at 06:57. I just don't understand how to make the wheels have propultion and to turn. Is it a mod/script?

do you have a tutorial video on how you built the suspension vehicle at 9:48 or at 15:43(that's where i paused the video). i have a resource truck i made that could use a suspension setup like that.

I would suggest using the Rotorwheels mod by Klime - way easier than manually trying to attach and also way more stable; attaching via buildvision doesn't always give the same rotor offset. Cool video though!

I tried to build a simple Custom suspention with the helkp of this Video...but i cant move the wheels...waht ever i confikurate the Axes...how you do this and did i need a mod/skript for this?

Interesting video

Let me give you an idea for Extreme ground clearense, build the suspension above the chassis , i mean this is space engineers there needs to be a way XD

Wow! Im here early 😅 Nice design 😊 Can we get a steam workshop blueprint link ?

Why dont you separat the right side from the left using a rotor per side/axel?

11:00 Well, if you knew your trigonometry, you'd not find it weird at all. While regular springs push back stronger the more you compress them, rotor-based springs get weaker. (In their lower quadrants. In their upper quadrants, they get stronger again.) Ever done some push-ups? It gets easier to push the more your arms are straightened out vs when the upper arm is mostly parallel to the ground. Same thing. The holding force is proportional to the absolute of the tangent of the sprung arm's angle against the horizontal, it's lowest at the horizontal, where it's only the rotor's torque divided by the arm's length, and it's theoretically infinite at TDC and BDC.

11:25 the term is obstacle course or test course

Here are some of my designs, in Part 3 I actually get a large mobile base climbing alien mountains. :) Crazy Suspension Part 3: kzfaq.info/get/bejne/n5logd2KldPbpnU.html Crazy Suspension Part 1: [also cool] kzfaq.info/get/bejne/gbqklrOF3MjMqps.html [Don't ask about part 2, it's just crazy!]

Metal gear music? Champ.

The wheel spinning at the start of the video though.

try make one with the green rod connecting to each wheel, that would be like the tank suspension works then.

wait how do you add a rotor to the wheel suspension block?

3:45 its literaly like ZIL-135

"i really want to focus on the 8x8" 9 mins in and i have yet to see the big 8x8 drive.

If you take the time to dial in the suspension on the standard rovers they arent as bad as shown here to be fair

i know i can pit block on suspension but i don't like that since it feels like an exploit since it is only possible with a mod.

You do realize that there are Left AND Right versions of wheels, discernible by which way the treads are pointing, yes?

12:30 i think it needs more weight maybe?

Looks like a hill climbing super buggy.

To be honest I enjoy the longer videos I don't have the intention span that most of these teenagers and young adults today have I've never seen such a generation with the attention span of a walnut

Took you 18 minutes almost 19 to mention it uses scripts, nothing about it in the description either. Nice suspensions tho, great work! Why aren't you linking your creations ?

2:40 - "Because these wheels have so much torque" No, torque has nothing to do with it. Suspension strength does. Namely, if someone forgets to adjust it to the weight and terrain roughness. Suspensions should be made as hard or soft as necessary to keep the wheels in contact with the ground and also to reduce the risk of fatal ground collision. All you're demonstrating here is that you suck at setting up suspensions.

Круто! Скажи пожалуйста, как ты поставил блоки к подвеске это мод?
