Re: What Pushed You Toward Mecanum Drive This Season?

Also, Mecanum Drives give you additional maneuverability to move around defenders while maintaining the same heading. (Easier to aim and keep ball)

Why kept us away from Mecanum was CoG issues. Most of the Mecanum Drives here have the majority of their robot's mass elevated over the wheels because suck a large opening is required between the wheels when climbing the bump which causes CoG to be substantially higher than most conventionally built skid steers. (6+ WD) Also, the added expense of Mecanum Wheels and the Additional Transmissions we would've needed were a factor in our decisions...
We used custom mounts which lowered the center of gravity, no transmitions unless your talking about gearboxes, but it dose eat up your cim limit.
