Abstract

Based on the mathematical curve named rational circular cubic [2] and on its animation, it was conceived an original mechanism generating this curve. The mechanism has an additional kinematic chain that provides the drawing point of the curve as the center of a variable length straight segment. There are given the successive positions of the mechanism and the drawn curve, as well as the similar curves obtained at different positions of the fixed vertical straight and the driving's element joint. Such a mechanism can be used in textile machines, as a toy, in kinetic art, etc.
