  1. I created this modified Bucket Wheel Excavator some time ago, and I thought I would like to share it on this forum. After building the original BWE, I wanted to try to incorporate some Mindstorms functions into it. I managed to motorise all the active functions, using both an EV3 brick and motors, as well as some PF motors. Functions can be preprogrammed, or can be remotely controlled using an EV3 IR remote. Here is a list of the functions: Bucket wheel rotation and main conveyor belt - PF XL motor Lower conveyor belt - PF medium motor Boom arm elevation - EV3 large motor Lower conveyor swivel - EV3 large motor Superstructure rotation - EV3 medium motor Driving - EV3 medium motor Since I owned an NXT as well, I used it to motorise the small mining truck that was included in the set. There are also some LEDs that illuminate the 'work area', but they don't really do a good job, its just a nice thing to include. Here is a video of the excavator in action, as well as the mining truck (sorry about the poor resolution and bit rate): More info about the machine can be found here: https://www.us.lego.com/en-us/mindstorms/community/robot?projectid=3e125a5b-475c-4a4c-b3ed-e4b4f2192907 Let me know what you think of it in the comments!
  2. Hi Guys! I would like to present you my latest build. Not usual small excavator truck. The target was to create small excavator truck with as many functions as possible. I wanted to build truck with 8 functions, to use all IR ports, but in this small scale, I only manage to put 5 and I put 3 functions to Dump truck in same scale. It was quite hard to put all functionality to such a small body, but the result is worth it. It has 5 PF controlled functions: 4x2 driving, steering with great steering radius, rotating platform, controlling beam and controlling bucket. Is very well playable and It can dig a sand/brick and it is enough powerful to take itself out of the ground. It's robust enough to survive young child play. More info about Dump truck can be found on my blog lego.tomashubik.com Some photos: More photos and indo are here: Excavator truck Dump truck VIDEO COMMING SOON...
  3. I got the Bucket Wheel Excavator in September last year, and after building it and modifying it (with Mindstorms), I dismantled it to use the pieces in my other Mindstorms creations. I'm particularly interested in the large yellow planetary gears/rings that come with the set, I hope to use them to create some sort of tank with a rotating turret. However, I'm not too sure about the geometry of the pin-holes in the rings, I don't really know where it is safe to attach a pin in a certain hole. If anyone knows of the correct geometry of the rings, it would be very helpful!
  4. Well here's my entry for the contest. I wanted to play a little with the new pneumatics so: A-Model: pneumatic forklift. It features: - Fork lifting of course - Fork tilt - Hog steering and functional steering wheel in the cabin - 4 piston boxer engine driven by the front wheels with differential - Pendular rear suspension - Forks width adjustable (manual function) Couple of images: I don't like cutting original Lego rope, so that's what you see in front of the front wheels. I used about 70-80cm of the 1 meter rope. The 8T gear in front of the seat was something I'd rather not do, but the 12T bevel gear for the drivetrain is right below it. The hog steering axle going right through the middle of the chair is also something I'd rather not have, but in the given space I had 2 choices: place the chair a whole stud forward and have it be too close to the steering wheel or move it a full stud back and have an axle sitting right in the middle of the chair. I decided on a compromise with the chair slightly angled. I used this part in the top of the chair so it wouldn't touch the hog axle, but still made both sides of the chair connected. Fitting the pneumatics with the drive axle and the steering above the drive axle meant I didn't have much room to play with, but it fits perfectly and to protect the pneumatics from the drive axle I added a 2L pin connector and 1L liftarm to the drive axle. Pretty straight forward manual function. I wanted to make the forks foldable too if I couldn't fit in the 10,000 stud limit, but considering the model is 34x14x17.5 (that .5 doesn't really show properly in the images, but the forklift mechanism is about 1/2 stud of the ground) I didn't bother with folding forks. So then the time came to make a B-model. Time to duplicate the main model so I knew for certain I had all the parts: The parts in front of the left one are the things I didn't install when I rebuild it, because I either forgot (diff) or bricklink came later (pneumatics). B-model: Bucket truck I really don't like making B-models, but I think this turned out ok. Of course there are things I'd like to do different, but that's the challenge of a B-model. It features: - Bucket lift (why do I even list this ) - 4 Outriggers - Hog steering - 2 cylinder boxer engine - 170 degree turning crane (manual function, radius only limited by hose length of pneumatics) A couple of more images Outriggers are handled by the small pump, I wanted to use both, but the lengths of hoses I had left were a limiting factor. Doesn't really matter, using the 16L axles to power the rear and front outriggers was already planned and I tried the system with 2 small pumps and they weren't able to really lift the model either, not more than 1 pump managed. One pump manages to get the wheels to have slightly less friction. Speaking of friction. For the outriggers I had to switch some pins on the A-model for LBG 2L frictionless pins to make it easy for the outriggers on the B-model. This change isn't shown in the photos of the A-Model, but can be seen in the images of these 2 models together (6 are easily visible on the front wheels of the forklift) and in the video. No parts were added. For every LBG pin added, one black pin was removed from the table. I find no fun or challenge in cheating the rules of the contest. I also didn't want to use more pins than really needed, where 2 were enough to fix a liftarm, that's what I used on the A-model. I already expected that re-using the A-model's hoses would be a problem, but it worked out ok (even for the turning radius of the crane). Ok, I cheated Lego's current hose code a little (2x black on 1 cylinder is old hose code), but the grey hoses were too short or far too long (which I used on the handpump). Speaking of the handpump, thanks 2LegoOrNot2Lego for your handpumps on BL, both used here Not intended, but this model fits in the same box as the A-model: 35 studs long, 13 studs wide and 17 studs high. A and B model and the parts remaining: Of course I'd like to have made a roof for this B-model, but I didn't really see how anymore with the parts I had left. I then decided to make an open truck like the old american fire trucks. Not that this is really intended as a fire (bucket) truck, but I can't deny that with the white and red it could be used as such (maybe reverse the colours). Here's the video of the models. I combined both into one video: Thank you for your time reading this topic and in closing this image:

    [A - A08] Kicking the Bucket!

    Location: A08 - Crentium Tags: Piracy, Spying, Civil I came over the rocks to find a small MANTIS beacon that I know is not supposed to be there! Yep, this has gotta go! This tune will summon the Leg-less men. The name is a misnomer, they actually do have legs! Ok, Leg-olas, I want you to punt that beacon as far away as you can! Great kick! Thanks for watching, that's all for now folks!
  6. So I'm sure we are all aware of the ongoing 'ice bucket' challenge. I have noticed many people have been nominating others from the Lego fan community to do this challenge, so I was wandering: how should we nominate Eurobricks users? Should we PM other users or have a topic?

    Boxes "as" plates?

    Over the past years, TLG rarely make newly molded plates for one individual set (the last one seems to be Scorpion Pyramid). They only leave bricks for kids to build and play solely, and we may additionally buy the basic plates: asphalt roads, green grassland or blue sea. At the same time, there is something "large and plastic" that TLC keep producing for years until today--- buckets, which are mostly used in starter sets and the current theme "Junior". Decade ago, I can remember that most other brick buckets of other brands have studs on their cover, which can be the base for child to build things on. I'm curious about why modern Lego boxes are seldom used in multiple ways, especially being the plates. They buckets are simply toy boxes, which means you can only use it to store toys. Even if there are plates included sometimes, the plates still have nothing to do with the bucket itself. Here are some similar Lego toys that have plates with product design, as I can remember. If there is something missing, please inform me here. My First Lego Set: The predecessor of curret Junior series. The bottom boxes are made of cardboard, only the cover is made of plastic brick plate. The example pics also show how can we play with the covers. Even though Junior has no brick-related container designs, surprisingly the starter covers were made in 2013. Racers miniturbo and fold-out series: the road plate is folded in the box. Consumers can open the plate and then fold it back to a cube. I wonder if they can be used in minifigure-scale City layouts, though I don't have such information. Thomas at Morgan's Mine: the bricks and Thomas the train are inside the mine, which is simply the whole product with a paper coat. Speaking of Thomas, there is a not-so-glad-to-hear competitor, MegaBloks, who now owns many Thomas sets using such kind of product design: Bridge&Train: the products simple make the trains under a cube bridge. The bridge can be used in different ways. Bucketes with Trails: the trails are molded on the boxes. Not only you can build things on the boxes, but you can make a train route in different heights and layouts. There could be some reasons why TLC isn't active in such kind of design. Practically, maybe general buckets use plastic that are harder than normal Lego bricks, so TLC can't massively producs such kind of brick covers. Or theoritically, the designers might think that using the buckets as plates or part of big buildings would be inappropriate for children to learn how to play bricks. But in economic aspects, I don't think having a playable boxing/package is a bad thing. What do you guys think?
