To elaborate a bit. We all chose our top-20 list. I think 10 of the finalists made it to each of the judges list. The other 10 were on 2 of the 3 judges lists, so we had to compromise (obviously). With help of a TLG representative the final 10 were chosen. To elaborate on the concept of the contest, "building your dream Porsche"; in the beginning I was disappointed by people building an existing Porsche, so I aksed the representative whether that was allowed. The answer was yes, so after that the judging was simply based on the four criteria. I had some of the future concepts on my list and I figure the other judges had too. But with over 100 entries, it's very difficult to choose the best ones. Half of the entries made it to everyone's top 10 list, so the winner will most likely be among those 10. But you never know.

Yup, I think it is!! Thanks John. Getting a proper lens, tripod and teaching yourself some lightroom skills will get you a long way I'm probably in the minority, but I don't care much for B-models. On occasion, I really like the B-model, for example the 42039. But most of the time I don't really take the time to build the alternate model. For this set, I think it's cool that they only changed the attachment. Shows the purpose of the mounts and PTO. On the other hand; a proper buggy could have been made (like with the previous tractor). Don't come here too often then. Will cost you a lot of extra cash (changed the links, thanks for the correction) Changed some of the bullets too. They mist the list tags. About the videos; they are visible, right?

I have considered it, but in the end I think gearing down will be the best solution. The finished robot will weigh a ton, so I think gearing down is necessary. The BWE already weighs around 5kg so this model will easily weigh between 10-20kg. But you might be right. That's why I want a modular setup, so I can try different setups.

Thanks! There's no right or wrong answer. Depends on what you like, whether you will be using parts for MOCs etc. Read the Arocs review and compare them. I like the CLAAS better but that doesn't mean I would buy if first. Arocs is a great set too! You can get the Arocs and later the CLAAS.

Which one was yours?

In which set did the red dish appear?

Exactly Agreed. I would love to see those digital entries built in real life. If it would have been an EB contest, we would have had two categories. And we would have a clear definition of a "dream Porsche". I didn't like the fact that most of the contestants built an existing Porsche instead of a dream version. But it was allowed so we need to accept it.

Sure, it will be a pneumatic model team Porsche contest. Starting soon

Been thinking about that. Seems like the best solution, but it requires some tinkering. Any suggestions are appreciated

That's a great solution, thanks! I do have some turntables Here you can see the dimensions of the Rotacaster wheel. There's a 10L axle going through it. When using the modular setup for the wheels, I could easily switch between different setups, three or four wheels.

It's for making WiFi connection. EV3 doesn't come with on board WiFi, so you need a dongle. In the early days this was the only supported by the EV3 firmware. If I am not mistaken, the smaller dongle is supported now too.

So what I basically need is something in the center of the black part of the turntable that can be linked directly to the hub of the Rotacaster.

MINDSTORMS EV3 OMNIDIRECTIONAL ROBOT INTRODUCTION The reason you are stuck with me as Moderator/Admin is actually caused by Mindstorms EV3. I proposed an Index for Mindstorms and Bonaparte figured I could make one myself. Resulting in me making one, and one thing lead to another. In 2013 TLG released a brand new edition of LEGO Mindstorms. Owning two NXT sets, which I had hardly used to build something cool, I was determined to change that when I bought the EV3 sets. I first bought the 45544 - EV3 Education Core Set set, and shortly after that I added the 31313 - Mindstorms EV3 (Retail) set to my collection. After some initial experiments both unit had been turned on approximately the same number of times as the NXT. This being a terrible waste of potential, I recently decided to start building the robot I have been planning in my mind for a long time. My goal is to build a fairly big humanoid(-ish) robot. Does that sound familiar? Of course it does, since my good mate Simon Burfield (Burf2000) has built a super cool humanoid robot recently. We also know him of the Wheelchair and Segway. And yes, he is a big inspiration to me. What I am aiming at is a Omnidirectional Robot with one or two arms and a Wall-e like head. The height of the robot will be approximately the size of a child, let's say around 120cm. Omnidirectional means allowing movement in all directions (more on that in the next chapter). Since I have no idea where this will end, I have created a WIP topic, in review style. I will add chapters along the way. When I add a new chapter I will post that new chapter and edit the original post. Feel free to comment, hint, tip, suggest, mock and ridicule Before we continue I'd like to give my man Burf and the guys at Rotacaster a big thank you! OMNIDIRECTIONAL WHEELS Here's the wikipedia description for Omni wheels: Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems. A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive. The Killough platform is similar; so named after Stephen Killough's work with omnidirectional platforms at Oak Ridge National Laboratory. Killough's 1994 design used pairs of wheels mounted in cages at right angles to each other and thereby achieved holonomic movement without using true omni wheels.[1] They are often used in small autonomous robots in intelligent robots research in the academia. In projects such as VEX Robotics, Robocup and FIRST Robotics, many robots use these wheels to have the ability to move in all directions. Omni wheels are also sometimes employed as powered casters for differential drive robots to make turning faster. However, this design is not commonly used as it leads to fishtailing.

From left to right: 125mm 48mm 35mm As you can imagine the 125mm version are for heavy duty applications. Since the robot will probably by quite heavy, I figured the bigger the better. There's also a 125mm version with 3 wheels instead of 2. However, this will probably suffice for my robot. The diameter of the 125mm is slightly larger than a 15L liftarm and the width is slightly less than 6L. CONCEPT Here's a simple concept sketch. And an artist impression of how the robot should look like. The end result will probably look nothing like this one, but it's nice to have an idea. PROTOTYPE I have started building the prototype. The idea was to buil in a modular fashion, but this early concept failed miserably. VERSION 2 The triangular shape poses quite a few challenges. Not that I hate a challenge, but I am contemplating on making a four wheeled version. The idea is to create 4 standalone wheel units, which can be attached to a center hub, possibly with shock absorbers. The red liftarms underneath need to be removed, because they will prevent the wheels to be mounted. This is just a simple LDD setup I drew, since we discussed Bob's problem with turntables. That made me rethink my setup. Some turntables and dog bones for the new setup. When using the modular setup for the wheels, I could easily switch between different setups, three or four wheels. My progress is what you see in the pictures. Now let's have fun discussing and mocking. Alasdair mocking in ...3....2....

Well, I read that it's actually not the first set to do that, right? I remember some discussion about it. But switching the battery is indeed very elegant and well thought of.

That's probably where I missed the 1L connectors I must admit that I was somewhat hasty when building. That's the downside of pressure. Well, we do have ourselves a nice competition. Spot the mistakes

Very sharp! Could have figured looking at the left over parts. Thanks. I will include your image in my review.

Hehe indeed. I was about to retake the picture, but I figured...let's leave it in the review.

Yup, you are right. That's the one that was missing.

Corrected! Are the videos visible?

Thanks. I will correct it.

I did prefer real models. I think you simply can't compare digital entries with real life ones. We suggested to split these into two categories next time. Probleem is that there's no way to tell whether a digital model actually can be built properly, whether the functions are working etc. And there's an unfair advantage in using all available colors. That's why I favored actual builds.

Are you sure? The videos have been made public. Can't see this?
