Re: Bumpers vs Frame which is better

Metal on metal causes a greater impulse, but evidently to a lesser magnitude in some cases.
That's what I was getting at. With the metal on metal/lexan the robots not only slid off each other they could spin each other better so that all the momentum transfer was not just in one direction. The lessen the impact along any given vector.

A couple other things:
If you attached your bumpers correctly they will not effect maintanence.

Bumpers will help the CG of most bots not hurt it based on what I've seen. Most have way to high a CG anyway.
