December 22, 201014 yr I am not sure about the angle, but the wheels on left and right have to be mirrored, so they all prepedicual to center of the vehicle when looking drom the underside. Hi, Thanks for the answer. So it has to be mirrored on the vertical center, what about mirrored on the horizontal center? I would expect that as well - no? Thanks, Noam
December 22, 201014 yr Hi, Exactly like I said :) They all "point" to the center, so they are mirrored horizontally and vertically. No, tgey all ahve to be like on this picture:
February 16, 201114 yr sniggerfardimundus posted 8 pictures on his Flickr photostream about this Mecanum Wheel design. He calls them "omniwheels", but others have correctly identified them as Mecanum Wheels. He shows "exploded" pictures to show how they are made , and he wrote, "I've been needing a larger omniwheel than the Metal Grudge that has seen so much attention recently, but I wound up with a wheel that was nearly six studs wide and still had the same rough ride ad the MG. This wheel is a bit heavier, but will fit in a space four studs wide at the rim and five at the hub. The ride is much smoother that the MG or my expanded wheel."

February 18, 201114 yr Hi I'm new here. After making an order on bricklink and constructing the wheels I ran into a problem. The small wheels automatically collapse in and rub against the inside dishes. I noticed on the Ldd file that some of the technic connecters are different colors. Does that matter? I'm new at technic so it might just be something obvious I overlooked.
February 18, 201114 yr @ Bioniclefan: Welcome to Eurobricks! Did you see Zblj's additional explanation on this post, concerning parts that could not be modeled/included in his LDD .lxf file?
February 18, 201114 yr Yes, I did put the tires on the wheels. What I'm having trouble with is that the technic connectors allow the small wheels to move to much and hit other small wheels or the plates with six holes. I noticed on the Ldd file that there's 6 in gray, 4 in black, and one in blue and white, does that have anything to to with it? Mine are all black. EDIT: Pictures.I circled problem areas. wheel against wheel wheel against dish Edited February 18, 201114 yr by Bioniclefan
February 18, 201114 yr Author Odd, my wheels didnt have such problems. Any way the new tyres might be larger than old ones?
February 18, 201114 yr @ Bioniclefan: Now that you have made Zblj's Mecanum Wheels, what kind of vehicle are you going to mount them on? Edited February 18, 201114 yr by DLuders
June 3, 201113 yr I created an account just because of this awesome topic. Now i know its been a while since anyone posted here, but the heck with it. I just ordered parts for 4 of the 2 version wheels, at the semi-reasonable price of $84 from briklink. Heres hoping German customs are efficient.
June 3, 201113 yr @ ba12348: Welcome to Eurobricks! After you build the wheels and place it on your vehicle, please post your creation so that people can see it!
June 4, 201113 yr I plan to, at first it was just going to be a forkift (the mast was a nighmare), but after seeing this <Video> I knew what had to be done. P.S. as someone who spends all day driving forklifts, I have to wonder why this company ever went out of business
May 6, 201212 yr [bUMP] Look at the SIZE of the Lego Mecanum wheels on this Lego Mindstorms creation (from AFOLCon 2012/The Lego Show, as photographed on domhodgson's Flickr photoset):
May 6, 201212 yr Pretty cool. I'm guessing it can move in any direction, and the nxt mounted low like that acts as a weight that keeps the motors from going around inside the wheel. Maybe I'm wrong....I dunno.
May 9, 201212 yr .What does it even do? tim It can move in any direction. Each wheel has its own motor and Eric (the builder) can make it do some magical things.
May 10, 201212 yr [bUMP] Look at the SIZE of the Lego Mecanum wheels on this Lego Mindstorms creation (from AFOLCon 2012/The Lego Show, as photographed on domhodgson's Flickr photoset): Wow - that is an amazing machine - I'd like to see that in action!
May 24, 201212 yr there is a youtube video of the mecanum wheels in action are there any instructions for the smaller wheels seen on the NXT vehicle??
May 24, 201212 yr When i saw the video on Youtube i was amazed! the huge wheel works beautifully. tim
May 24, 201212 yr WOW!!! That video is very impressive! I had never seen anything like this. At first, I could only wonder how it works... I thought that after seeing it in action, I would get a better picture of that... But no, I'm just as perplexed as in the beginning. Some other awesome creations in that video by the way. Thanks for the link.
May 24, 201212 yr @ VASH321: At the 2:48 portion of you mentioned above, it says "Improved design from Jernej Kremlj" (who is "ZBLJ" on this forum). His Vector Racer Mecanum wheels are found in his Brickshelf gallery (complete with Lego Digital Designer (LDD) .lxf Building Instructions file). His YouTube video shows the in action:
May 26, 201212 yr when you look at this at 0:27you see that the kinda look like the third design from ZBLJ but smaller?
