8110 - Unimog - MODs and Improvements

@Alasdair Ryan

Nice idea! That is a clever way of using the drum to wind up the hoses.

You can't expect any thing else but great ideas.

Without seeing the actual design, I will guess it uses the same phenomena as the drive wheels on a regular car without diff-lock. If one wheel get stuck and the other is hanging free, all drive will go to the free wheel. Same here - the support leg that hits the ground first will stop and all force is transferred to the leg that is still in the air.

Hmmmm, that's a pretty genius idea! i will have to incorporate that into a model.

You can't expect any thing else but great ideas.

haha of course .

Tim you will be pleased to know i build a quick idea of the legs with a diff in the middle and it works good.

Here is a video of the self leveling legs.

Hally loo ya 20 times that taken to post it.

Would you mind posting photos? I would like to see the diff.

Here we are.

Ahh very nice. Does it work well in your opinion?

It works great although when retracting it does tend to leave one side retracted for longer,(thay sometimes don't both go down at the same time)

I have not tried using a older diff,maybe this might improve it more.

You can say that again........ oh you have,see what happens when you try to drink and write at the same time.

To easy and full remote control.

And here is the ready ldd file of the crane from "pcility".

Could any one convert this into PDF or something. Im on a new computer and for some reason wont open anything in my LDD. I dont know if its possible or not so any reply is welcome. Thanks.

@Montage

I've had this issue also. Have you tried opening free build in LDD Extended mode or Lego Universe mode? Using those two would be the best because of some of the pieces wouldn't be placed correctly in normal or Mindstorms modes. But for whatever reason LDD no longer imports a model if you're in the home screen, but will open if you're in building.

I have made a pdf file of the instructions to the crane made by PeterB.

Hi folks,

my son (9 years) has got the 8110 to christmas. He has nearly finished it but there's a strange beahviour when he tries to drive and I'm not sure if there is a problem or if the steering is really so strange.

When he moves the unimog forward or backward he can only drive approximatly 20-30 cm and then it seems that there is a really heavy resistance and the whole powertrains seems to have a heavy torsion. Also the two yellow "gear wheels" (I don't know how to name these things, sorry) in the middle of the unimog and below the cabin (they are connected with the steeering wheel at the top a the cabin) are rotation while moving the unimog.

When he rotates the front left wheel forward the back right one moves backwards. :-((

Is this normal?? I don't think so but I'm afraid he has made something wrong an must disassemble the whole thing.

Any suggestions or help is really appreciated.

Thx in advance.

Regards

Alexander

PS: If it's the wrong topic or forum please tell me.

@ Alibaba7: Welcome to Eurobricks! It sounds like your son has made an error with the Unimog's drivetrain. Let's look at this TechnicBRICKS 8110 Review for some good pictures and videos of the innards of the 'Mog. The yellow parts you were talking about are called "Knob Wheels" -- they offer a non-slip gearlike connection.

I recommend looking at the many videos posted there on that TechnicBRICKS review, and seeing if your 'Mog is constructed correctly.

in which directions atre moving the front and rear tires when you are moving the central differential? both axles in the same direction?

thx for the info

do you mean the gray part with the three light yellow gear wheels inside next to the battery box? If yes, it's nearly impossible to rotate it by hand. But it rotates if I use the steering wheel at the top of the cabin. Then both axles moves in the same direction. Also the front wheels moves from left to right.

@ Alibaba7: Can you look at Blakbird's 8110 Renders to see if your drivetrain looks like this? The center differential (with the three bevel gears, as you noted) should rotate:

I'll do that tomorrow morning with my son together. Thx for the info with the renders. Wow. With with soft is this made of?

I think I found at least one mistake. The center diff is in the wrong direction. I have to turn it around. I hope we don't have to disassemble the whole thing. THANKS!!!

Ok I'm supposed to be getting my unimog tomorrow!!

But it was on backorder and i had to push my own limits to get it before Febuary.

So first thing im going to do is make a cabin lift, that will keep the cab suspended and have a slower downward motion.

I will use use part 53586, Technic, Axle and Pin Connector Perpendicular with Extension, from Rotor, set 7162; which is orange and I'm hoping its Unimog orange.

And with that piece, I will use part x1739, from Bionicle Axonn, set 8733; which is black, so I thought the combo would be better

Part 53586: http://www.bricklink.com/catalogItem.asp?P=53586

Rotor: http://www.bricklink.com/catalogItem.asp?S=7162-1

Part x1739: http://www.bricklink.com/catalogItem.asp?P=x1739

Axonn: http://www.bricklink.com/catalogItem.asp?S=8733-1

I will also mod the steering so that it is easier to turn.

And at some point i will fully remote control it and make some other functions, possibly motorized outriggers.

Having the differencial the wrong way can certainly cause this problem. However, whilst you are in that area, you may want to check the series of light grey and darg grey 16t gears that run verticly above the centre diff to make sure there isn't a light grey one where a dark grey one should be and vica verca.

[T_Tank]

Question on making the unimog RC. Is there a way to reduce the tendency to bump steer when one of the front tires hits a obstical? I'm using a geared down M motor but it really fights to hold the wheels from turning more or less while moving.

[efferman]

you could use a wormgear
