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 (?).

| (...) 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. (...) (22 years ago, 15-May-03, to lugnet.robotics)
