[Industry research] SIRB DL : 0: In this paper it is studied the dynamics of the robotic bird. The system performances are analyzed in terms of time response and robustness. It is study the relation between the angle of attack and the velocity of the bird, the tail influence, the gliding flight and the flapping flight. In this model, a bird flies by the wind beat motion or using its tail down. The results are positive for the construction of flying robots. The development of computational simulation based on the dynamic of the robotic bird that should allow testing strategies and algorithms of control.

[Industry research] BiologicalRobot DL : 0: This paper presents the development of computational simulation and a robotic prototype based on the dynamics of a robotic bird. The study analyze the wing angle of attack and the velocity of the bird, the tail influence, the gliding flight and the flapping flight with different strategies and algorithms of control. The results are positive for the construction of flying robots and a new generation of airplanes developed to the similarity of flying animals. Some highlights are given about the fist implemented architecture of the structure of a robotic bird. This platform consists on a body, wings and tail with actuators independently controlled though a microcontroller a radio transmission system and batteries are used in order to avoid wired connections between the computer and the robot.-This paper presents the development of computational simulation and a robotic prototype based on the dynamics of a robotic bird.

[Industry research] EMFII-lecturenotes DL : 0: Electromagnetic theory is essentially a study of some particular field. We define a field as a function which specifies a particular quantity everywhere in a region. If the quantity is a scalar (or vector), the field is said to be scalar (or vector) field. Examples of scalar fields include temperature distribution in a building, sound intensity in a theater and electric potential in a region. The gravitational force on a body in space, the velocity of raindrops in the atmosphere and the velocity of fluid particles in a fluid motion are examples of vector fields.

[Industry research] 04177616 DL : 0: In this paper, sliding mode (SM) observers are proposed to replace expensive sensors used for the measurement of tires forces, vehicle side slip angle and vehicle velocity. These estimations are done for two important purposes: The ﬁ rst is for the estimation of the forces and parameters needed for vehicle control, while the second is for the diagnosis preview based on the safety region for each parameter and state.
