Re: paper: Mecanum: we can't even agree on pronunciation?

What is the "this" being referenced? Are you proposing that this statement is true or false?
I'm assuming you are talking about the italic bold part. This was supposed to be interpreted as a 2nd voice that the paper is trying to persuade. After reading your post and re-reading the section I agree it is poorly connected to the previous part (sorry). the "this" you referenced should read:

Quote:
ThisA force of 10lbs in the plane of the wheel would imply that a mecanum wheel creates MORE force than the same size regular wheel. You could even put a regular wheel in contact with the mecanum wheel but at a 45 degree angle to increase the amount of torque. Since they are the same diameter wheel you get more torque at the same angular speed which equals more power.
Let me try and re-state and see if that helps:
if 2 identical motors put out identical torque to 2 wheels of the same diameter, but 1 is mecanum, then the mecanum wheel translates this identical torque to a larger force than the regular wheel. If you mount them as stated this larger mecanum force would translate to the regular wheel. If the regular wheel is then put in contact with the floor, the REGULAR wheel would now be translating the larger force to the floor.
(so far all correct--here is the incorrect parts in italics)
Since both wheels have the same radius, they will rotate at the same speed. More force at the same speed equals more power

clear as mud now??

***because of these problems I've just updated to rev3 and added another picture
