Then a kind of motion model is designed and an instance of Vega class is created to manage the device, through which the specified device is introduced in the scene simulation application based on Vega.

This paper introduces the methods to define user defining motion model (UDM), and steps to realize UDM in Vega.

Three locomotion modes are presented,i.

This paper discusses the three typical locomotion modes of biological snakes, and describes the development of a snake like robot with three dimensional mobility.

This paper expounds the motion principle of snakes in the view of biomechanics, presents a design of snake like mini robot and gives a basic motion pattern of the robot.

Maneuvering target tracking algorithms should estimate target motion mode and eliminate influence of glint noise at the same time.

In tracking maneuvering target,target state and target motion mode must be estimated at the same time,and parameters or structure of filtering function should be modified according to estimation results,so that it can reduce the difference between filtering function and target motion mode,and increase tracking accuracy of maneuvering target.
