4 Mecanums vs. 4 Plaction/4 Omnis
Hi all!

Just curious on everyone's thoughts.

For this challenge (2014 Arial Assist), what do you all think is the best drive train? Right now, my team has a prototype of a drive train using 4 grippy plaction wheels for the center and 4 omni wheels on the outside corners. It looks like this:

-----{}-------{}------
--------[]--[]---------
--------[]--[]---------
-----{}-------{}------
{} = Omni
[] = Plaction

It's all connected with 4 CIM motors. 2 CIM motors paired with 2 Sonic Shifters. This thing is STRONG!

Our other option is a basic 4-wheel Mecanum drive.

What's everyone's thoughts on these two types of drive trains? I'm voting on Mecanum purely on the maneuverability, but other's argue that they won't be strong enough to push robots around if needed. I feel that if we are maneuverable enough, we don't need to worry about pushing robots.

Thoughts?
