The polar moment of inertia of a closed orbit curve of a point under one-parameter closed planar motions was studied by H. R. Müller, [1]. We study the polar moment of inertia of the enveloping curve of a line under one-parameter closed homothetic motions of planar kinematics. AMS Mathematics Subject Classification (2000): 53A17, 53A04

In recent years among developers of robotic software formed a direction of the development of individual solvers. Such solvers are designed for specific hard problems. In this paper we consider an approach to design of an efficient solver for the problem of placement of visual landmarks. Mathematics Subject Classification: 68T40
