The LEURRE started in 2002, the aim is to create mixed groups of cockroaches and robots and to see whether the robots can control the insects. Researchers have to isolate the cockroach pheromones and spray them on to a "dress" which covers the robot. Their task is to make the robot's chemical "dress". With this smell, the robot will be accepted by the cockroaches as one of them. Once the robot is chemically dressed with the pheromones sprayed by the researchers, it is placed among ten males in…

Experience of two model hurricane merging. Second phase : experimental generation of two hurricanes. Laser allows to visualize the flows in 2d and 3D. The engineers use a stick to plunge a string covered with fluorescein - coloring agent which allows to trace its evolution on the surface (2D) and below (3D) - in the tank. The hurricane vortex is generated by the gradual opening of two flaps. Researchers study the impact of the Coriolis force effects - a geophysical force generated by the earth…

A researcher experiments the vortex dynamics in a thin-layer fluid. The laboratory experiment consists in pulling a disk in thin-layer fluid to produce a vortex. The coloring agents allow to visualize the movements of cyclones (red) and anticyclone (black). The experiments are used to improve the meteorological and climatic forecasts.

Standing above the Coriolis turntable (14 m in diameter, 1,2 m high, weighing 150/300 tons, 0 to 3 revs/min.), an engineer studies the simulated formation of a hurricane with digital imagery which allows to take precise measurements. Laser allows to visualize the flows in 2D and 3D. Researchers study the impact of the Coriolis force effects - a geophysical force generated by the earth rotation - on atmospheric turbulences with this world's unique rotating platform.

A researcher makes a cockroach and a robot meet. The robot isn't yet dressed with its chemical envelop on which the researchers will spray cockroach pheromones. The LEURRE started in 2002, the aim is to create mixed groups of cockroaches and robots and to see whether the robots can control the insects. Researchers have to isolate the cockroach pheromones and spray them on to a "dress" which covers the robot. Their task is to make the robot's chemical "dress". With this smell, the robot will be…
