Can anybody explain to me what a "Centroid" is?
I know what a COG is, here in this groups it means a robot that moves the
center of gravity to hold the balance when walking (?).

I presume you realise that COG and centroid are only equivalent for a body
of uniform density?

hi ppl

are we using COG TLA cause we like TLAs
or because we differ COG and centroid?

I used it because it is commonly used here, and because it is short.

Besides, Mario and Giulio Ferrari use the term in their book, so it is
good
enough for me :^)

btw i like TLAs so COG is cool

(...) Centroid and COG (center of gravity) are at the same location if you're considering an object of uniform density. This is usually the case so the two terms get used often to describe the same thing, and their definitions become the same. (...) (21 years ago, 15-May-03, to lugnet.robotics)
