It has been years after the unspeakable and the survivers used whatever machinery they found to make a new start. The last bit of civilization was rebuilt in a form of the mobile base nicknamed the FrankenBase due to the nature of it's design. Frankenbase was assembled from the following leftovers: Buckets and bogies from a pair of tracked loaders Front frame, suspension and axles from a monster truck Command bridge and helipad from a stranded ship Crane and two containers were salvaged from a dried up port The base also features three support vehicles, a quick buggy, a small bulldozer and a helicopter: To propel the massive base, all wheels and trackes are driven and suspended: The suspension allow the massive vehicle to easily crawl over rough terrain: The track bogies can also steer, giving the FrankenBase a very tight steering radious: The only way to acces the abse is by lovering the ladder in front, which also serves as the ladder to acces the walkways surrounding the entire vehicle: The crane uses a special mechanism which locks onto containers in order to move them: The command deck is protected by nets and features controls: View of the backside with the crane raised: Some trivia about the model: The entire model took me around 2 weeks to build All functions are powered by 19 motors and controlled by 6 BuWizz bricks It measures over 130 cm long, 45 cm high and 40 cm wide The weight is estimated to be around 7 kilograms This is my second largest model built, first being the Go-kart It's one of my most eccentric builds ever The different colors are intentional, representing the chaotic nature of it's envoirment Size compared to the Liebherr: See the model in action the video:
So after a rather poor start I decided to totally reimagine and rebuild the Mercedes truck of the future. It all started with a random idea of routing 4 functions through a turntable like this: After fiddling around in LDD for few hours I came up with an 8 function gearbox powered by a single RC motor: The functions shown are: Orange - RC motor drive Lime - Horizontal extending od outriggers Yellow - Vertical extending of outriggerd Violet - Slide and tip of the bed White - Rotation of main arm superstructure Light gray- Rotation of claws Red - Lift of main arm Warm gold - Movement of claws Dark gray - Rotation of scondary arm After this rather unusual design process it was time to think of the basic shape of the model. I was inspired by the 42038 arctic truck's layout, but I wanted to add my own twist to the formula... Here's the result: Here you can see the massive cran arm used to pick up various loads: The truck uses four of the biggest Lego wheels in front and 4 tracks in the rear: As you can see all tracks and wheels have fully functional spring (and additional pendular for the tracks) suspension. Also notice the massive bed tipping angle. The truck also has a fake V8 piston engine driven by the tracks: And a prestige sand-colored interrior: Steering is done via HOG and the spare tyre behind the cab: Here's the description of the concept idea: _________________________________________________________________________________________________________________________________________________________________________________________________ This is my model for the future 2045 Mercedes-Benz competition. I named it Antos and it has several features: The engine is Euro 11 compliant 6-stroke aqua-diesel-electric hybrid. The additional 2 strokes inject water into the hot engine with expands as steam adding another work cycle. The engine also powers an electrical generator which is used to power the truck's front wheels. Front wheels also act as a generator while braking, therebye returning the electrical power back to the batteries. Tracks are driven directly by the diesel engine. For optimal performance the front is equiped with many air surfaces which reduce drag. Because this is an offroad truck, the massive wheels and 4 tracks in the rear provide it with massive traction area, which reduces ground pressure and preserves ground vegetation. The multi-functional arm and bed are driven by a single motor using a mechanical multiplexer mechanism. The Lego modes uses solid axle suspension in front, suspension on all 4 rear tracks, a fake V8 piston engine driven by rear tracks A powerfull RC motor powers the 8 functions. I managed to reute 4 functions through the turntable in order to fully motorize all arm functions. Total number of gears used for arm and bed (not including steering and fake engine gears)is over 130 making this one of my most complex switchboxes to date. The front was slightly inspired by the Unimog 400's sloped cab, but with added wings and a lower bumper. The idea for the tracks and arm actually came from the 2014 Lego technic arctic vehicle. The rear bumper is in a shape of a V in order to allow the bed to slide out and tilt. Interrior is detailed with seats, steering wheel and handles in prestige sand color. __________________________________________________________________________________________________________________________________________________________________________________________________ And as usual here's a short 3 minute video. (3 minutes is max time so you may pause some text) I hope you guys like the truck, I personaly think its a very retro-futuristic beefed up advanced half-track concept and in that sense something different and original.
Hello! This moc was made a while ago (last year), but I realized, there is no topic about it yet. I wanted to make a heavy and fast trial truck from Zis e134. Original model: My version: folder: http://www.brickshel...ry.cgi?f=496827 Basically, it was built for truck trial race, so it has a "propulsion motor/weight" ratio, each RC buggy motor carries ~ 1 kg. There are 4 buggy motor built in, each axle has one. Only two gearings (40:8 and after that a 24:8 reduction) are in the drivetrain in each axle, so I hadn't problems with efficiency. Total wieght became 4190 g. I used 1957 parts to build it. It's my longest and heaviest trial truck yet, total length is 610 mm (width: 283 mm). The 4 motors give enough power to reach 1,7 km/h top speed (flat surface), I used two RC units to power them. I think the most important part in these 8x8 trucks is the suspension. I tried to make a long travel one, which allows the wheels to make contact with the ground in extreme terrain also. The rear axles are built in a unit, which has a linkage (see pictures). This unit can bend also, but not sideways. The two front axles can bend sideways, and lenghtwise also. So without springs, the suspension does it's job: The second and third axle are connected together with these bars. They seems weak to here, but I can say, there weren't problems with those during the tests and races. They don't hold the axles, only make positioning, but of course, some force can be appear: Bottom: I made some details, like net in the driver's door, flags, grilles to the front: This truck was able to drive in heavy snow.
