Zero moment point is a concept related with dynamics and control of legged locomotion, e.g., for humanoid robots. It specifies the point with respect to which dynamic reaction force at the contact of the foot with the ground does not produce any moment in the horizontal direction, i.e. the point where total of vertical inertia and gravity forces equals 0 (zero). The concept assumes the contact area is planar and has sufficiently high friction to keep the feet from sliding.

Famous quotes containing the words moment and/or point:
“Here is what sometimes happened to me: after spending the first part of the night at my desk—that part when night trudges heavily uphill—I would emerge from the trance of my task at the exact moment when night had reached the summit and was teetering on that crest, ready to roll down into the haze of dawn....”
