We present an algorithm which, taking as input positions of features (corners) in every single frame of an image sequence and the sequence itself, will generate an image of a three dimensional object optimally textured. Optimally means that for each constituent triangle of the created mesh, the texture of the best resolution will be chosen. The spatial shape of the object shown in the video sequence is calculated using a factorisation method and the best texture selection is a solution proposed by the authors.

The paper discusses development work related to the gait synthesis of walking machines prototypes. The problem of the influence of the leg posture on the leg-end/ground interaction is presented. It is shown that, by the choice of leg posture, the expected ground friction coefficient which prevents leg slippage can be controlled. The design of tip-over motion is shown.

The object of our research is electromechanical controlled biped walking robot. The purpose of the work is to develop numerical parametrical optimization methods for control of walking robot by taking account of transient in the circuits of electric drive. The criterion of optimization is the minimum of electromechanical work. With classical variational control methods, for the simplest model of overturned mathematical pendulum, analytical solution of optimization problem on the fixed interval of time is constructed. Power consumptions under the walking control of multi-linked walking robot are analyzed.

Path planning for an underwater vehicle can be formulated as a multi-criterion optimization problem that can be solved by genetic programming. Two underwater vehicles are compared. For assessment of an underwater vehicle trajectory, three crucial criteria are used, a total length of a path, a smoothness of a trajectory, and a measure of safety. Some rules of genetic programming are described.

In this paper, a new hybrid network; FLN-ANFIS (functional link net-adaptive neuro fuzzy system), is proposed and used as a controller for robot path tracking purposes. The advantages of the ANFIS controller along with fast learning rate of FLN are combined to propose a new methodology for controlling robot arm movement. Furthermore, a classic PID controller as well as the intelligent controller such as NN, fuzzy and ANFIS are developed and their performances are compared both by simulation and implementation. A 5-bar linked robot is chosen as a test system for implementation. Simulation and implementation of different controllers under various conditions are carried out on this robot. Results show that the designed FLN-ANFIS network for robot control can provide very good performances through a wide range of operations by improving dynamic operations of the system.

The theory of modelling and control of airships was mostly imported from the fields of science and engineering of underwater vehicles. However the main hypothesis of rigidity of the structure may be improved to take into account the flexibility of the hull of an airship. We present an approach for analysing dynamic elastic deformable airships in an ideal fluid. Our model uses the updated Lagrangian method in combination with a large displacement and small deformation (Green) strain tensor formulation. Analogy is made with classical structural dynamics. The description of the behaviour of the airship consists of a continuous differential equation that is solved using a Rayleigh-Ritz technique combined with the finite element method. The method proposes also to take into account the coupling between the rigid body motion and the deformation as well as the interaction and coupling with the fluid surrounding.

This paper discusses discrete sliding mode control for two-link rigid robotic manipulators with uncertain modelling. The discrete sliding mode control problem is formulated. Necessary and sufficient conditions of stability along with the effect of sampling are stated. The discrete controller is shown to lead to a stable closed-loop system. Simulation results are presented to illustrate the features of the control scheme.

In this paper we propose a method to model the spatial uncertainties of the B-spline surface patch and consider the effect of work object localization uncertainties. The spatial uncertainties are analysed by studying the error covariance matrix: eigenvalues in the direction of the eigenvectors. The methods are tested with an actual robot system and Monte Carlo simulation. We also give results from the behaviour of the system when the level of input noises are changing and study the resulting uncertainties.
