Midsized bulldozer with PoweredUp (looks inspired by a Komatsu D71)

[Appie]

I'd like to show my latest creation, a bulldozer with PoweredUp

It's looks are inspired by this bulldozer from Komatsu, a D71:

It has the following functions with a PoweredUp Technic hub:

• 1 L-motor for drive
• 1 L-motor for steering through a subtractor
• 1 M-motor for blade lift
• 1 Medium angular motor (from Spike) for the blade angle

 

 

Belly shot. Subtractor design is from PawelCh.

Technic fig compatible 

An attempt was made to give the impression of an engine below the engive cover   

Directly below these few plates is the M-motor and directly below that is the Medium angular motor.

 

At the moment I made my Pybricks program give the blade 3 different kind of angles: all the way to the left, straight or all the way to the right. I could make smaller steps, but this seems sufficient at the moment. The edges on the blade going forwards is perhaps not normal for a dozer with a blade that can do angles, but since this will be running at an event later in the year mostly in a forward fashion, it's more useful. The very small angle of those tips of the blade and being almost parallel with the tracks when the whole blade is angled, should still give a desired result of Technic bushes (our "dirt" for the event) being moved to the side. The little wheels on the bottom of the blade are to protect the panels a bit from scratches and whatnot 

 

At the maximum extension of the LA's it can lift itself a little bit from the ground.

 

At its highest point, the blade has 2 studs ground clearance. Not much, but it's the best that I could manage in the given space.

 

Removing the batteries from the hub is pretty doable. The roof is attached to 1 black pin at the back. The 3L axles with stop and half yellow bush at the sides can be pulled out to remove the center part of the cabine easily. The cabine is only attached by 3 pins to the the rest of the body work: one pin below each door and 1 half pin at the rear. If there isn't a Technic fig in there, the power button is easily accessible through one of the windows/doors.

Thanks for watching and I hope you like it.

A video might take a while to make time for to make sorry.

That is very cool. Great design and features.

It looks very nice and smooth for panel based moc. I wonder how it would look like all yellow like model that inspired you. Now it has kind of Liebherr color sheme

[Thirdwigg]

Very clean design. I like what you did to access the battery box, and the little wheels on the blade is a pro move.

Great job.

Great job I like the old komatsu colors.

Thanks guys for the compliments! 

@jorgeopesi Honestly I forgot the similarities to the old Komatsu colours. I picked these colours because I liked how they look together and have plans for other equipment with the same colour combination. I guess Komatsu had similar ideas long, long ago 

@1gor I can see the Liebherr-ness of the colour scheme. It certainly was an inspiration, because I am quite fond of that yellow machine and often white roof (and cabin) combination.
