What is center of gravity?

There are two correct answers to this question; The average position of the robot s weight. and The average position of the robot s mass. When an object is at the center of gravity, it is equal on all sides. The center of gravity can vary depending on the object.

Take for example a ball, like a basketball. The center of gravity would be in the middle because the weight is equal on all of the sides of the balls. When it comes to humans, our centry of gravity would be above our ways, because the top half of our bodies outweigh the bottom half.
