Quinn McGinley yeah the diagram is incorrect, when the top right and bottom left wheels move forward, it moves the robot up and to the left in the direction both of the rollers are facing. In the diagram it shows the robot moving the wrong direction that what it would normally
if go all time at 45º let se to NE or SW and never or very few times go to NW and SE wo the wheels in this diagonale are stoped. Dont make to much friction and destroy that wheels?
Are your mecanum wheels set up in an x shape? The most common problem is that teams will set up their wheel directions wrong, thus the vector math doesn't work out. So make sure that your setup looks like an x.
Before running any code, perhaps ensure that all four of your wheels are positioned correctly, as shown in the video. The rear left and front right wheels should have the rollers in identical orientation, and vice versa. After ensuring this, when coding, each side (left, right) pair of wheels should be counter-rotating, yet, the two individual sides should be counter-rotating inversely. For example, if the rear left wheel is rotating clockwise, then the front left wheel should be rotating counter-clockwise. However, the rear right wheel should be rotating counter-clockwise, and the front right wheel should be rotating clockwise. Ensure all wheels are spinning at an identical speed. This will allow your bot to strafe in either direction.
If you check RC cars using them, at high speed it gets extremely bumpy. Braking is putting forces on weird angles. Basically, each wheel on it own isn't really breaking, but together they manage to stop on every directions. And uneven ground is a big problem, you may want to add shock absorbers to make sure you never loose contact. Otherwise it can slide in wrong directions. Usually it's pretty bad for high torque or high speed.
Correct me if I'm wrong but I think the force diagram provided at 1:53 is incorrect.
Maybe the non-rotating wheels push the car in that direction instead of the rotating wheels?
Im not sure either...

@@juule5494 mechanically speaking, that's exactly what happens ... just that it's supposed to go the other diagonal
Yes, the force diagram is incorrect. C'mon goBilda... get it right.

now I know you cant really recreate drones in rainbow six siege
you need 4 wheels to pull the movement off
Three omni wheels mounted at 120 degrees from each other can also create a holonomic platform. ruclips.net/video/zjFmYDxpxUM/видео.html
On your site is the price for just one wheel or all 4 of them ?
3:!5 Center of gravity matters!
Do you have one that’s an inch or half an inch
Can the omni go to any direction, like 30° without turning it ? not only 45° angles and forward back right and left angles.
Yeah the omi wheels should allow you to move in any direction like a dot on a piece of paper. So wherever you move the stick the robot should go
What is that square metal framing called?
That is our Aluminum U-Channel! www.gobilda.com/channel/
@@goBILDA thanks, do you have a .sldprt file for it? I want to model before I build.
thanks a lot bro
Tak faham
Driving forwards, backwards, and turning works fine, however, I am not able to strafe sideways.

can i put macanum wheel in real car.
1. speed almost 50-55km/h.
2. does brake works?
3. does it works on gradient?
