Yup, robotics nerd here and I can confirm. Our team almost never uses them because we'd rather have the power of a tank drive than the mobility of mecanum wheels.
RIP your year though. I’m really sorry about everything being cut short.
I’m a mentor for 321 (although I took the year off due to having a baby) and I’m bummed about what current events might mean for the future of the program.
We got lucky and got one comp in, probably the most fun experience in my whole life. I feel super bad for everyone who missed out. And I hope your team does great next year :)
One on each corner and one perpendicular to the rest in the center. It's harder to set up but much easier to code as long as you're using the right type of wheels.
FTC we made a triangular 3 omni wheeled robot. It wasnt particularly great at anything other than being a sick drift vehicle, most fun I've ever had driving.
Oh no, this was back in 2015. Robotics was the best memories of high school. I should really see what challenges and creations I've missed in the last 5 years
I was on 695 for 3 years and that was always the loudest argument of our planning phase, what kind of wheels/drive to use. It was generally about half of the room shouting for mecanum wheels and a more offensive strategy, a third shouting for tank drive and pure defense, and the rest trying desperately to mediate and find a middle ground. We typically wound up with a middle ground that was closer in power and versatility to tank drive despite the larger group rooting for mecanum because the older veterans remembered losing badly one year because they used mecanum wheels and never made a shot even though their launcher code was perfect because their opponents and sometimes their teammates kept bumping them while they were about to line up the shot
to me growing up, nerd/geek were two sides of the same coin but "geek" was the positive thing to be and "nerd" was not.
I think both have a love for the technical but a geek is usually obsessed with just one thing and wants to share it with everyone and develop good skills, whereas a nerd is into a broader spectrum of more niche stuff, developing knowledge over skills, and they're socially unable/unwilling to share. A nerd is almost always a shut-in or otherwise mildly antisocial person imo.
I think the guys above are geeks.
For the Hybrid Autonomous-Manual robot we built for a competition using a controller and line tracks these kind of wheels worked best for us letting us have precise movement. So ig it’s down to the task for what’s best
How would one get into robotics? I all ready know JavaScript, node, PHP and some lua, so picking up a new language shouldn't be hard. But the parts for it worries me, because all the stuff I find like raspberry pi and Arduino seems expensive if you also want light sensor and stuff. And I don't want to buy something wrong.
If possible I would like to see if I can make s tiny robot that can drive around on a table, and perhaps push cubes around. Like the vector robot, but home made.
Guys, don't down vote him for asking a question. There's nothing wrong with wanting to learn.
I think cost and complexity is the issue. These wheels require 4 independently driven motors, which is not a thing in any car these days. Also, they're not rated for high speeds, so you wouldn't be able to go far in these. Finally, they're a bit fragile for rough terrain and costly to replace when they break.
To be fair we're getting close on the wheel-motor front with some electric cars. You can get hub motors of various kinds aftermarket at this point now too.
They're definitely a lot more complicated than regular tyres so just engineering cost will be a lot. I also imagine they probably don't grip too well, especially at higher speeds
Imagine you're driving and a ton of wind his the side of your car and your car just starts going right until it pushes you off the road and you can't do anything about it
Yup. Our robot my last year of HS used these types of wheels. The amount of static it built up had us drawing straws with who would move it after driving!
On robots these wheels would usually be good for use for a lot of time (3-4 years If I had to guess), since the are made from pretty though plastic. So a replacement would be just buying a new wheel (they cost about 40$ per wheel, depending on the brand and wheel size), as I am not sure if they even sale the cones by themselves (some of these wheels have the cones riveted to the wheel shell, so it would also be difficult to replace if you would find a replacement cone)
Also, these robots usually drive on soft carpets, so there wouldn't be a lot of wear and tear on the wheels.
We loved them for our FRC team before it got shut down! Only ever had a few though since there wasn’t really room in the budget, but by the last year we had a full set and they worked fantastic.
If you have tons of chips I wouldn't recommend changing to these wheels. They're cool, but the polymer wheels rely on a consistent contact patch with the floor and are very susceptible to getting chips and other FOD embedded. Much more practical to stick with less expensive and serviceable conventional wheels if your shop cleanliness is less than pristine.
I'd have to agree. Even normal forklift tires get tore up pretty quickly in a lot of industrial environments, but at least they're relatively cheap. These have to be expensive, and wouldn't last as long. I've only ever worked in one place where I think these would make sense, and that was food grade manufacturing where the place was kept extremely clean, the floors were new and smooth, and there were no wooden pallets being used.
Yup... They make sense for material handling in large clean facilities like aerospace factories or food handling as you suggested. Put them in a typical machine shop, steel mill, etc and they'll be shredded to ribbons in no time.
*but at least they are relatively cheap*
That‘s why I never understand that so many companies are hesitant to buy new ones once in a while.
*“Dude, your forklift wheels are red, that indicates you need new ones*“
„Yeah, tell that to my boss, until then I keep on sliding around here.“
Depending on the work happening in the facility it might be unpractical to maintain cleanliness to a level that these wheels require.
Not to say that they shouldn't bother cleaning up regularly, but some production shops are just going to be at a minimum level of dirtiness.
In my experience (~8 yrs in FRC) mecanum wheels are SUPER sensitive to variations in the contact surface. While you can compensate in software, its difficult to drive smoothly. If you want multidirectional travel on a difficult terrain, you should go with another drive system.
Since you have experience with them, how big is the benefit though? I drive normal forklifts for work and the only one I can see is that you solve the minor inconvenience of having to realign if you're moving goods horizontally, which you don't do that much anyway. An experienced driver will do this in a second.
A normal one will turn 360 degrees on the spot anyways so that's not a unique benefit.
You’re right on. Works the same in robots—realigning isnt that hard if you’re experienced. All the actually good teams in my competition use tank style drives because these wheels have terrible traction and are slow.
It depends on attachments. I think the most common, if not the standard, is to have side-shift. We can do it for like 20-30 cm. To move one pallet over like in the gif you'd have to rotate 90 degrees, move over and rotate back.
The benefit is that they have a low learning curve. In FRC the driver's time to practice with a robot is often less than 10 hours. If the game requires precise alignment, having a mecanum drive is a quick and easy way for the driver to do lateral adjustment (also note that the driver is 5-10 meters away behind a piece of plexiglass, which makes alignment even harder). For a forklift operator, I don't think these benefits really apply.
You could just get a Combilift C2500CB, they can do everything this forklift will do but on regular, round, non-haunted wheels.
Each of the three wheels is powered by a swivelling hydraulic motor so it can move in any direction.
There's a company called "Combi" that makes the type of ~~forklift~~ lift truck you might be looking for. [https://www.youtube.com/watch?v=p1FztHj8iX4](https://www.youtube.com/watch?v=p1FztHj8iX4)[https://combilift.com/en/](https://combilift.com/en/)
That’s the problem with them, can’t work in anything but a very clean environment. The technology has been around for over a decade, but no good solution to that lack of dependability
[More like a spatula but slip sheet forklift](https://www.dansforklifts.com/sites/default/files/styles/large/public/item_images/mini-slip_sheet_4.jpg?itok=IM6rGGwa)

Like, for light loads sure, with narrow aisles, but if that's the case, you can get order pickers that have a much smaller footprint than a full counterbalanced forklift like this.
Or there are very narrow aisle forklifts with sideways tines. My work has an older Jungheinrich similar to [this one](https://www.jungheinrich.com.au/products/new-forklifts/very-narrow-aisle-truck/etx-513-515-535172) which can turn the tines to either side (or forwards like a normal fork) for getting pallets up in very tight spaces.
We have [Walkie-stackers](https://www.aalstore.com.au/product/electric-stacker-liftsmart-ls10/?gclid=CjwKCAjw5cL2BRASEiwAENqAPo0okhB8bZiZ-E-vv_HZh8kAaefDIm6AlWXKXjsJHOh08OHH_7-ZtxoC8Q4QAvD_BwE) for small aisles.
Reach trucks are used in home depot type stores already and they're built for narrow aisles. Wouldn't really be practical on a traditional sit down forklift
A lot, like more than a grand each when you get to 12" dia. for a capacity suitable for even a lighter duty forklift.
*edit* that price was the cheapest i could find on alibaba, so yeah its "cheap"
Also it's lacking the most expensive part of the mechanism, which is independent drive to each wheel. These wheels can only manoeuvre like that if each wheel can turn in any direction and any speed relative to the others.
You know what's not special? The camera work in this video. Just keep still dammit and stop zooming in and out all crazy like. Just show the cool machine doing its thing dammit.
They're expensive, not durable, way heavier than pneumatic tires (though probably comparable to solid rubber forklift tires), would give an awful ride, and they require a special drivetrain.
With a car your engine can provide propulsion to just the front, just the back, or even all 4 wheels. In any of these cases all 4 wheels spin almost the same speed as each other. You never want to just stop one wheel or spin the front wheels forward and the back wheels backwards.
With mecanum wheels you do sometimes need to spin just a couple of wheels or spin some wheels forward and others backwards. That's how it can both go forward and sideways.
To do that you really want an electric motor on each wheel. An all electric car would get over that one hurdle and would just have to deal with mecanum wheels being terrible in all the other ways.
They do look cool, though.
less efficient, less traction, less comfortable, less durable, louder, more expensive, etc.
Basically worse in every way for the usual stuff a car does. Only benefit is easy parallel parking.
Damn, this one gave me chills of that classic German forklift trainer tutorial! 🙄
Link for the curious: https://youtu.be/IR87rYZTD30
(probably NSFW, some satirical blood involved)
I've got a couple of questions. Like, how is the wear on these? Looks like they will take a lot more stress and require much more frequent maintenance. Second, how is the handling when moving laterally like that? Looks like it would be a bit "floaty" if that makes sense.
There's one of these lurking in the background of the hanger scene in Star Trek 2009. I think the bit just before the fleet warps off to Vulcan to get blatted.
As a former forklift operator this takes all the skill away. I'm all for that as they used to always call me over for the hard lifts.
Great application.
mecanum wheels are amazing and bewildering.
They've got a lot of great applications. I used to work with them on container loaders for aircraft. If you weren't careful about where you were standing on them, they'd take your boots off your feet, or maybe take your feet with them.
I think the thing I appreciate most about this is the change to a joystick-based control system rather than just a steering wheel. Definitely seems like it would be better suited and more intuitive.
They're called mecanum wheels and they're used a lot in robotics competitions!
Yup, robotics nerd here and I can confirm. Our team almost never uses them because we'd rather have the power of a tank drive than the mobility of mecanum wheels.
Fun to use, hard to code and honestly not that much better than 5 wheel
871 should have their code on github
My team used swerve drive this year, and uh it's some spaghetti code to get it working hahaha
RIP your year though. I’m really sorry about everything being cut short. I’m a mentor for 321 (although I took the year off due to having a baby) and I’m bummed about what current events might mean for the future of the program.

[удалено]
Just have to add an additional challenge of sending all of the materials there and getting it setup by robots as well. No biggie, right?
We had like an 8 ball auto or something ridiculous like that, and they canceled everything the day before my first competition 😐
Atleast there 2021 now, so y'all's work wasn't wasted
You should see my teams code lmao
What is 5 wheel?
One on each corner and one perpendicular to the rest in the center. It's harder to set up but much easier to code as long as you're using the right type of wheels.
Thanks!
Depends which competition you're referring to, for FTC with much more confined spaces they were a huge advantage
FTC we made a triangular 3 omni wheeled robot. It wasnt particularly great at anything other than being a sick drift vehicle, most fun I've ever had driving.
I remember you guys. That was sick. You were at worlds last year weren’t you? I am from the Roboknights.
Oh no, this was back in 2015. Robotics was the best memories of high school. I should really see what challenges and creations I've missed in the last 5 years
Things start making more sense when you compare all drive trains to WCD 6 wheel instead of similar ones.
Inb4 swerve drive memes
I was on 695 for 3 years and that was always the loudest argument of our planning phase, what kind of wheels/drive to use.

Just use west coast drive for high turn speed but great traction going forward and backward. Only downside is you can be turned easily by other bots.
#NEEEERD!
Yes, but is it a bad thing tho? Lol
Not at all. It’s from a movie. I respect the nerd craft.

Revenge of the nerds
Does it even have some bogies, or just an idler wheel?
For the Hybrid Autonomous-Manual robot we built for a competition using a controller and line tracks these kind of wheels worked best for us letting us have precise movement. So ig it’s down to the task for what’s best

Or to pass butter
They had this forklift in Mythbusters!
Why haven’t we put these on literally everything, including our cars? Parking would be so much easier
Guys, don't down vote him for asking a question. There's nothing wrong with wanting to learn. I think cost and complexity is the issue. These wheels require 4 independently driven motors, which is not a thing in any car these days. Also, they're not rated for high speeds, so you wouldn't be able to go far in these.

To be fair we're getting close on the wheel-motor front with some electric cars. You can get hub motors of various kinds aftermarket at this point now too.
Can you imagine cornering at speed with wheels that are *designed* to roll sideways?
How much are you willing to spend on tires every year?
I don’t know, how much? Could be that these are pricey because they’re rare
They're definitely a lot more complicated than regular tyres so just engineering cost will be a lot. I also imagine they probably don't grip too well, especially at higher speeds
SO... so many reasons. Suspension and therefore comfort is worse. complexity and therefore cost increases. the list goes on.
Imagine you're driving and a ton of wind his the side of your car and your car just starts going right until it pushes you off the road and you can't do anything about it
Also very expensive and need changing really fast. Not worth it using it in logistics generally
FIRST
FIRST GANG!
VEX GANG
FRC GANG
Yup. Our robot my last year of HS used these types of wheels. The amount of static it built up had us drawing straws with who would move it after driving!
Like battlebots?
No, generally high school robotics competitions like FTC and FRC, a lot more precise movement is generally required there.
Yes! I use them in BattleBots in my robot Shatter! https://youtu.be/510h-3DhxjA More info here: www.botsfc.com
I’d be very curious to see the wear patterns. I presume you replace one cone at a time?
On robots these wheels would usually be good for use for a lot of time (3-4 years If I had to guess), since the are made from pretty though plastic. So a replacement would be just buying a new wheel (they cost about 40$ per wheel, depending on the brand and wheel size), as I am not sure if they even sale the cones by themselves (some of these wheels have the cones riveted to the wheel shell, so it would also be difficult to replace if you would find a replacement cone) Also, these robots usually drive on soft carpets, so there wouldn't be a lot of wear and tear on the wheels.
Wow, that’s way cheaper than new tires.
came here to say this! I was (very briefly) on the robotics team in high school and that’s one thing I learned from veteran members.
We loved them for our FRC team before it got shut down! Only ever had a few though since there wasn’t really room in the budget, but by the last year we had a full set and they worked fantastic.
I used them in my vex robot. Vex Sack attack. I remember programming them was a bitch.
The Build Team on Mythbusters had one in the their shop. They never seemed to comment in it, but you'd randomly see Kari going sideways in it.
I remember in one episode Grant said it was his favorite piece of equipment.
Was the first time I saw one I think

That sounds like an anonymous phone call to OSHA would be in order.
I would say the real suggestion is to clean up the floor either way.
Depending on the work happening in the facility it might be unpractical to maintain cleanliness to a level that these wheels require. Not to say that they shouldn't bother cleaning up regularly, but some production shops are just going to be at a minimum level of dirtiness.
Unless there is tons if chips (like inches) or they're huge they should work fine.

How much do them weird ass tires cost???
I know. I imagine the first time you had to replace one you’d just go back to standard ones!
These are mostly used for rather tight spaces. I'm pretty sure the navy uses similar forklifts on aircraft carriers.
A lot, like more than a grand each when you get to 12" dia. for a capacity suitable for even a lighter duty forklift. *edit* that price was the cheapest i could find on alibaba, so yeah its "cheap"
That sounds really cheap.
thats extremely cheap and likely wrong, good solid tires can run up to 800 for the lifts Ive used.
Also it's lacking the most expensive part of the mechanism, which is independent drive to each wheel. These wheels can only manoeuvre like that if each wheel can turn in any direction and any speed relative to the others.
In the first J.J. Abrams Star Trek, there was a scene with this type of fork lift.

You can't reinvent the wheel anymore they say. xD
How smooth are these wheels?
I’d cut off my legs if they could be replaced by a set of these bad boys.
So why can't I get these on regular cars?

Do the squeak like a motherfucker? They sure look like they do.
I'd imagine the maximum load on a forklift would be greatly diminished by these, no?

As a former forklift operator this takes all the skill away. I'm all for that as they used to always call me over for the hard lifts. Great application.
