I can't believe that who would be able to make this one, it's incredible .Super nice
Its just a start of robotics we should dreams about achieving more in future i hope👍
Very cool design. I really enjoy Mecanum wheels, although they can be a hassle when they slip. I've only used them on relatively clean surfaces.
Are you using encoders on your motors?
Mecanum wheels can be used off road. They just need a closed loop drive system. You need to be able to able to monitor the speed of each wheel.
@@ddegn Yeah, I use encoders. Specifically, I worked the kinematics so I could navigate quite accurately while making pretty much arbitrary maneuvers, but as soon as a wheel slips the gig is up. I spent a lot of time trying to ensure floor contact was flat and pressure even across the 4 wheels to prevent that. Probably not a big deal if you're not relying on the odometery for navigation.
@@ddegn mecanum wheel's oval rollers bearing will clog up in off road scenarios though...
@@TheRealMRS It depends on how the wheel is designed. I think there are ways to make the wheels such that they would work as well as skateboard wheels and other wheels with bearings.
It's my intention to makes a Mecanum wheeled 4WD skateboard. I am worried about all the bearings I'm going to need. I might not be able to drive the skateboard off road but I'm hoping it will work OK driving down a paved road.
Vex makes some good Mecanum wheels. I have a couple videos showing my Mecanum wheeled robot on my channel in case you're interested. You can also search my username on Hackday IO to see my Mecanum wheeled robot project.
I think your mecanum wheel eskateboard is a good idea!

@@ddegn in offroad scenarios there are rocks and small debris on ground (e,g, mud or rocky road), no matter how you design the mecanum wheel, fundamentally mecanum wheel's design has gaps between each rollers, which will clog up when debris jammed between the rollers.
Not to mention dirt,mud and moisture, etc affecting the roller bearings.
Even industrial grade mecanum wheels can not guarantee to work in offroad scenario.
VEX's mecanum wheel are not really rated for heavy load, I dont think they are good either, imo it is more like a plastic toy grade component....
----
I used metal mecanum wheels like this in the past, each wheel is rated for 20kg load, might be helpful for your application:

I would recommend using stepper motors for the robots configuration
Absolutely amazing !
wow Pringles made such a nice robot!
Very cool concept and design.
However, I wonder if it could be made better by instead of using a rigid outer body like this design has and instead replace that with a semi-rigid yet flexible internal structure.
Sort of like a spinal cord.
That way it could make tight or gradual turns even while in small spaces.
The reason I bring this up is because I would have to imagine that if it came to a 90 degree turn that was shorter than the length of each segment of the body that it would be incapable of taking that turn.
Whereas if it had a rigid yet flexible structure as its core it would be able to, in a sense, snake its way through that turn.
Think of something like flexible electrical conduit.
Nature is the greatest inventor of all time.
Why not follow suit?
Best of luck to you in the future and keep creating.
its not weight balanced. Bad for mecanum grip / aspalt friction.
true but when in the U shape both wheels have equal pressure (not other shapes)
also i think it is meant to be used in pipes and on factory floors wich will be flat enough for mecanum wheels to work
@@harrysarso nope, in the U shape it will be imbalanced to one side due to the connecting beam, unless the other side is made heavier as well
the location of the batteries makes the counterweight internally, genius
@@harrysarso even on flat surfaces the weight needs to be evenly balanced
Where did these wheels come from? are the motors inside those same cylinders?
I got these mecanum wheels from AliExpress. I then took the them apart a used the rollers in my own wheel design which has been 3D printed. The Wheel has an internal gear which is driven by the motor inside the wheel.
Good design awesome
MASHAALLAH khub valo video
Awesome
Does anyone know a RUclips channel where they teach you robotics. I really wanna learn more about it
What's your current experience?
@@MatthewHoworko zero...
Well, there's 3 main areas to learn for robotics. Hopefully this can point you in the right direction:
Electronics - Start with buying an Arduino Uno board. This will let you learn how to use sensors and motors together. You can find all kinds of sensors and Arduinos at websites like SparkFun or Adafruit. There are lots of RUclips channels about Arduino. Some good channels: EEVblog, Robert Fernec, GreatScott!, element14 presents, ForceTronics, DroneBot Workshop.
Mechanics - You can learn software like Fusion 360, FreeCAD, Inventor, and SolidWorks to draw/plan your mechanical design. Pen and paper works too for some things. You can find all kinds of motors and mechanical prototyping parts at websites like ServoCity, Studica, etc.
Software - There will be programming in the electronics part, but learning how to program computer software in languages like C#, Python, Java, etc. will let you control & configure your robot remotely.
@@MatthewHoworko Thank-you.
@@MatthewHoworko hey does you know yt channel where they teach odometry and pid ?
On top !!!
Now design this with the wheels at least 2x bigger and program it to climb stairs by flipping end over end..
That would be of no use you moron READ what its for. Robots are simple and crap atm they are made to do one job or maybe two similar ones. how about you detach your arms and legs then just stay there until someone kicks you.. why not? not designed for it huh.. well i'm you do it anyway cos i'm Dumb and don't know how things work.. and dont understand why your being mean.. because that's the way i was made
@@Nick-jf7ku okay sourpuss...just because YOU have zero imaginative capability, has no bearing on the ingenuity and willingness of others to tackle a problem. Enjoy your misery.
@@glutenfreegam3r177 excellently put
@@Nick-jf7ku wtf
@@Nick-jf7ku I'm pretty sure making a robot flip end over end to climb stairs is one of the simpler solutions to the problem
Impressive😍
Hereafter, there is no more need for any other Robots!
This "Macaroni' will take care of every other thingamagics!!
How can I make one? Can anyone help.?
@jamesbruton You seeing this?
I could see this being broken up into 6 different sections instead of the 3 you see here. More flexibility and independent steering of each wheel.
much wow. doge love it
Nice
Make more vedios like this
how well does it work on loose sand, or grass? On a hard surface like that, regular wheels seem more optimal. I don't see this winning any robot battles.
“Nuclear decommissioning robot”
Yeah but since when you can make a 90 degree turn with a standard wheel without having to move forward ?
@@whosayink9026 you know those wheels that swivel? the ones on the legs of your desk chair? those wheels can go any direction. Just put the driver wheel on a 360 degree rotor, and bam, any direction. Well, any direction along the surface.
@@brocksamson3282 It is not that simple. Try it on an office chair and you will see there is a noticeable resistance difference when you try to turn. It will cause unstable or unpredictable motion as you rotate them 90 degrees. It is important because the angle of the wheels will have to change a lot. On the other hand omnidirectional is smooth, reliable and hustle free. But if you insist then make a robot and send a video of it. Let me now if you accept the challenge or not.
@@brocksamson3282 And by the way not every robot is made to win a battle.
Super
Me encanta
cool idea but i guess its not good on uneven ground
This robot would do very well exploring lavatubes in the moon and mars
Mass center is the weakest part of this construction
Wow
so this is pretty much a mecanum drivetrain but:
servos can make it a stick or an l
servo rotates arm up
arm has a servo on it like a turret
turret has camera on it
high school robotics teams do mecanum drivetrains every year, and im sure it wouldn't be hard to add that stuff
still looks nice tho, not to discourage you lmao
maravilha
Ok I came here to say that's such a stupid design... Until it moved horizontally in the U form. But I have to pull your funding, nuclear decommissioning doesn't pay the bills. How can we apply this to warfare?
Woa🤔🤔🤔🤔🤔
I feel like an ftc team could make something better
Meet the STUTTER BOT lol
ikr?
