Re: 8" Mecanum wheels and KOP wheel brackets

I will repeat what I said in another thread about this idea. I would be VERY careful about adapting the KOP wheel brackets in the manner shown in that picture. If you cut away that much material from the bracket, you are severely compromising the ability of the bracket to resist lateral forces in line with the wheel axle. A lot of testing was done with the bracket/KOP wheel assembly. If the bracket is made of thinner material, or if enough material is removed from the bracket, bad things happen. If the wheel/carpet coefficient of friction is high enough, and the impact energy is high enough, the bracket will bend and fold when the robot is hit from the side by another robot. So let me be real blunt here: don't do this. If you do, you WILL regret it.
