[MOC] 6x6 Tracked, Articulated, Flatbed

[Superkoala]

 

Some month ago, I found a random image of what looks like an exploration truck.

As i did not have enough info on the real machine it was impossible to use it as reference, so, some choice have been made:

• Mini size : not enough part to build something big when I started (other stuff in progress and cancelled since, that's why)
• A classical front wheel steering would have been possible, but very fragile due to the size of the vehicle. And I will need a pivot + linear actuator system for a future project, so it was a good opportunity to use it.
• No differential, because size matters.
• Suspension if possible
• Tracks, of course.

 

The full album is available on FlickR.

 

Power function part used :

• 1x PF-M for Steering trough mini Linear Actuator
• 1x PF-M for AWD propulsion without differential
• IR receptor
• Rechargeable battery

Cabin is reaaaaaly ugly. One day I will be able to make cool design.

 

Unfortunately/fortunately, after I had finished this little boi, I found a new picture of the real vehicle. But not searching with "arctic/exploration truck", I had all wrong since the beginning. This thing is actually an Oilfield flatbed truck: the Cossack from ATK:

Guess what ? It will soon be a real thing. Bigger, with some function.

Best regards

Hi! This is neat. I really like it. I can't call it simple, but somehow it looks just right for the scale.The suspension setup is original and works really well. May I ask you about the gear ratio from the motor to the tracks? I am really surprised the thing drives so well with a medium motor for propulsion. Congrats on a great job!

Very nice! I really like this model, including the cabin  (I think it looks quite nice and modern), and I am impressed with how smooth it drives. I can't wait for the larger scale model.

Interesting prospect. However, I don't like the cab. Nice overall!

Unusual vehicle, nice interpretation. Please could I ask what the silver pieces are, that you used for the exhausts and fuel tank?

I really like this, looks very advanced, maybe it could be motorized!

The reduction is just 1/3 (8t/24t), it's enough for this light vehicle.

The silver part are Wheel hub Part 55981 (here: https://www.bricklink.com/v2/catalog/catalogitem.page?P=55981&idColor=67#T=C&C=67) There is 8 like these in the Extreme Adventure (#42069) set

I did not notice if you use rubber parts from 42069 set to prevent slideing on smooth surfaces...Project is interesting
