Prepurchased mecanum wheels

[techedguy]

My points on this matter are these:

1) Designing, manufacturing, and running your own wheels is a great experience in the processes, design, and skills needed to fabricate just about anything. But if you custom make something, you can't reuse it later on.

2) COTS wheels, while not as good, are COTS so you can use them again. In a competition relying on fundraising for a budget, COTS parts can be recycled and repurposed...huge advantage.
