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: 1) item.taobao.com/item.htm?spm=a230r.1.14.61.72e216fbyQIOyl&id=564774142068&ns=1&abbucket=8#detail 2) item.taobao.com/item.htm?spm=a230r.1.14.19.4f1433f5iuRH73&id=538854272067&ns=1&abbucket=8#detail ====

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.

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

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 KZfaq 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 ?

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

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.

ikr?
