Hamilton's principal function — The Hamilton s principal function is defined by the Hamilton–Jacobi equation (HJE), another alternative formulation of classical mechanics. This function S is related to the usual action, mathcal{S}, by fixing the initial time t {1} and endpoint… … Wikipedia
Cartesian coordinate robot — A cartesian coordinate robot (also called linear robot) is an industrial robot whose three principal axes of control are linear (i.e. they move in a straight line rather than rotate) and are at right angles to each other. Among other advantages,… … Wikipedia
