[MINI] [WIP] Wheeled Excavator

[VKTechnic]

Last night I started work on my second MINI Challenge model...a wheeled excavator. Here's the chassis design, only 55 parts and it has 4 wheel steering.

Now to work on the hardest part: a good-looking digging arm.

But there is nothing to stop him from building two entry,but then picking the best one and only entering that one....

I seem to enjoy finding loop holes in Jims work.

Plenty of people are making more than one "mini" model. It's a nice challenge with the 200 piece limit, no need to get your knickers in a twist about it (this is a phrase used in England, I don't know how frequent it is in other countries )

The undercarriage (?) is looking really nice, the 4 wheel steering is pretty neat looking forward to seeing you get annoyed when you get to 201 pcs like everyone else seems to be

I also mentioned this

Jim's work has many errors to exploit

You get yours in a twist quite a lot don't you.

A troll as ever

[Rockbrick]

by judging peoples reactions to multiple models it will give you a better chance of success putting forward the public chocie over choosing your personal favourite one.

[ms09]

That's a nice try, Looking forward to seeing the complete model.

BTW, if you implement the steering function with gear rack above the gear, I'm afraid it wouldn't work smoothly. That's a difference between LDD and reality.

That's exactly what I'm doing: Building multiple models and choosing the best one, and entering that. I did the same thing for the Triple Build Contest

That's a nice try, Looking forward to seeing the complete model.

Everything I model in LDD is only for a parts count, I'm building everything with physical parts alongside the digital version. Steering works very smoothly, nothing to worry about

Progress:

Took me about 5 tries, but I finally got an arm design that I'm somewhat happy with. The main boom will be moved via a worm gear system, and the other sections of the arm will be moved by hand. Parts count is around 90

Looks to me like the beginnings of great build :thumbup:

This is turning out to be one humdinger of a competition!

...That's exactly what I'm doing: Building multiple models and choosing the best one, and entering that...

One build posted. Two builds posted. That's more than I've come up with

Hats off you you all

Progress! I'm at 188 parts right now, still a little room to improve. So far, I'm really happy with how this thing looks, and it's very nice to play with.

[legomuppet9]

The arm looks interesting, I'd like to see how it works

[Lakop]

So far so good. It will be interesting to see the boom arm in action.

[GoldVillage]

Smart done, you nailed it! cause its not easy to build the bent boom in the right angle of degrees

[VKTechnic]

Finally got the final picture edited!

And the obligatory parts picture:

Now which one do you think is better, the excavator or the ATV?

As of now, I'm siding with the ATV.

Edited July 15, 2014 by Victor Kojenov (TFOL)

[grum64]

Both are excellent models and each would make a strong entry in the competition but if I have to express a preference I say go with the ATV.

I think it's great.

[Eraman]

ATV better a lot

[Rockbrick]

mini ATV - its cute and fresh and there are too many excavators in the lego world already

I think you need to work on the front steering hubs a bit - those would snag on objects if it is to be an ATV

otherwise you're limited to smooth surfaces...

here's how I did it in my 8 wheeler mini trial truck in the end, originally I started out differently - Lego has done similar before
