Re: Another Drivetrain Idea - "True Octanum"

Interesting, now I want someone to build it to test how it performs compared to a standard mecanum drive.

Unfortunately though, I don't think that the added weight/design complexity would be very worthwhile. If I am understanding this design correctly, any gains you get in the strafing direction will come at the expense of the forward backward direction.

For example, under a normal 4-wheel mecanum setup, top speeds might be something like 10fps in the forward direction and 5fps in the strafing direction. With the same reduction in your setup, my guess would be that you would see more along the lines of 7fps in both the forward and strafing directions (whichever directions you so choose those to be).

I suppose that if you wanted the robot to handle more like a swerve drive than standard mecanum, this setup could help. I know our driver did not like field-centric code with mecanum wheels since his max velocity was dependent on which way the robot was facing.
