No, i think i know what I'm saying as confusing as it may be, let me explain then feel free to correct away(i might want to pursue this idea of mine). It has already been established that this system is going to be implemented in four different treads each at a corner of the robot, my idea is to instead of having the rollers 90deg from the direction of the tread moving as shown in the picture, have them set at either a 45deg or 30deg and leave the treads parallel to the other side. My reasoning for believing that this may work is that if you imagine traditional tank treads as just an elongated and spoke-less wheel that travels in an ellipse to move its load instead of a circle, setting the rollers this way will function as nothing more than this perception applied toThese Mechanum wheels on the first page, with all the drive and other characteristics of the wheels applying to them. If this however is too confusing because my mind works in strange ways the treads will be positioned like

and the rollers positioned like

just an idea and ill try to make a more detailed drawing to clarify what i mean when i get time
