The robot preferably comprises a plurality of navigation sensors providing signals for enabling the robot to navigate over the surface, and one or more detectors adapted to detect the presence of deposited material on the surface and provide signals indicative thereof. The navigation sensors may include one or more collision sensors and/or proximity sensors. The collision sensors may include one or more lateral displacement sensors arranged on a peripheral sensor ring to provide 360° collision detection, and/or one or more vertical displacement sensors. Utilising a generally circular shape together with a control regime which scans for the best direction of escape after the robot has become stuck (say in a corner) is especially advantageous. Furthermore, it may be additionally advantageous to detect the angle of any collision, in order to optimise the robots subsequent angle of movement away from the obstacle. 1, record 1, English, - collision%20sensor

Afin d’aider un robot à se localiser, celui-ci est muni de capteurs. En robotique, deux catégories de capteurs sont identifiées, soit les capteurs proprioceptifs et les capteurs extéroceptifs. Les capteurs proprioceptifs perçoivent les déplacements du robot d’un point de vue local à celui-ci et ne font pas usage de repères dans l'environnement, comme un accéléromètre, un gyroscope ou un odomètre.

Gyroscopic precession ... When force is applied to a gyro, the device reacts as if the force had been applied at a point 90 degrees from the point of actual application, in the direction of rotation. Precession affects propellers, which act like gyros, and gyro instruments. Its principle effect is on the heading indicator, which tends to drift over time. 8, record 23, English, - precessional%20motion
Record number: 23, Textual support number: 2 CONT
A gyroscope will not only resist being moved out of its vertical position, it will also generate force as it attempts to travel in large, circular patterns. These patterns are most easily seen with a spinning top. As the top begins losing its energy, it never simply spirals straight down in the same direction that it was originally spinning. As it destabilizes, it will always begin slowly rotating or precessing in a slow, even circle that is in the opposite direction to its normal spinning motion. These circular patterns are known as "precessional" motions, and they are another aspect of a gyroscope's movement that will occur either in air or in a vacuum and can be used to overcome gravity. 9, record 23, English, - precessional%20motion

Indicateur de virage et d’inclinaison latérale. [...] Le principe de base gouvernant le fonctionnement de l'indicateur de virage est la précession gyroscopique. Le rotor est monté sur un cardan. Lorsque l'avion effectue un virage à droite ou à gauche, le rotor «précesse» autour de son axe de rotation et fait rouler le cardan. À son tour, le mouvement rotatoire du cardan fait bouger l'aiguille sur le devant de l'instrument. Un ressort renvoie le gyroscope au neutre lorsque l'avion cesse de virer. L'indicateur de virage indique le «taux» de virage et non «l'amplitude». Le taux standard, ou virage au taux 1, est égal à 3 degrés par seconde ou 360 degrés en deux minutes. 3, record 28, French, - indicateur%20de%20virage

Quand elle tourne face au vent, l'éolienne agit comme un gyroscope, et la précession essaie de faire faire volte-face en avant ou en arrière à la turbine. Chaque pale est soumise à une force de précession maximale lorsqu'elle est verticale et minimale lorsqu'elle est horizontale. Ces changements cycliques de pression sur les pales peuvent vite fatiguer et casser la base des pales ou fausser l'axe de la turbine. Dans l'optique de réduire les contraintes dues à la précession, les éoliennes modernes ont trois pales, de sorte qu'une seule pale est soumise à une précession maximale à la fois. Le défaut historique majeur des éoliennes était d’avoir un nombre pair de pales, de sorte que deux pales étaient verticales en même temps.

Plutôt que de tourner autour de son axe horizontal, comme le fait l'indicateur de virage et d’inclinaison latérale, le gyroscope est incliné d’environ 35 degrés. Ainsi, lors d’un mouvement autour des axes de roulis et de lacet, la précession fait rouler légèrement le mécanisme du gyroscope. Le cardan est relié à un avion miniature sur la face de l'instrument.

The single-axis inertial platform... The angular motions of the controlled member are sensed by the single-axis gyro. The output signal of the gyro is electronically processed and fed to the torque motor (TM) of the stable element and to the torque generator (TG) of the gyro. The problem is to determine how to do the electronic processing so that the controlled member maintains its orientation in spite of disturbances. The voltage across the output signal generator (SG) of the gyroscope is proportional to the integral of the angular velocity of the controlled member about the gyroscope's input axis. Consequently, this signal is fed to an amplifier and then to a motor, which drives the controlled member in the proper direction to null the ouptut of the gyroscope. 1, record 46, English, - output%20signal%20generator

Rigidity in space. The gyroscope resists turning. When it is "gimbaled" (free to move in a given direction) such that it is free to move either in 1, 2 or 3 dimensions, any surface such as an instrument dial attached to the gyro assembly will remain rigid in space even though the case of the gyro turns.

L’inertie gyroscopique, appelée aussi effet gyroscopique, constitue la propriété fondamentale des gyroscopes.

(Par exemple, les occupants d’une voiture sont projetés vers l’avant quand celle-ci s’arrête brusquement parce qu’en raison de leur inertie, les corps continuent leur mouvement vers l’avant même si la voiture s’est arrêtée.) Lorsqu’on parle d’inertie gyroscopique, on fait allusion à l’inertie que possède un corps qui tourne. Tous les objets tournant autour d’un axe ont tendance à maintenir une orientation fixe, c’est-à-dire une direction de rotation et une position fixes, si aucune force n’intervient.

[The] Precession/Nutation Card ... provides the digital logic for spin sectoring, precession commands, active nutation control and engine mode selection. The spin sectoring portion receives a sun-centered pulse from the PAS and an input from the spacecraft clock. With this information available, the spin period is divided into 128 parts. The current sector status (position) is maintained and updated throughout each spin cycle. This logic information on the spin status is interfaced with both the precession command logic and active nutation control logic. In the precession logic the current sector status is compared with a ground command consisting of three parts: sector ID to start firing a precession thruster, sector ID to stop firing a precession thruster and the number of consecutive spin cycles during which the precession jet will be fired. 2, record 61, English, - precession%20command

The Two Frame Gyroscope. When the rotor is spinning and the spin axis is in a horizontal plane a definite resistance will be felt owing to gyroscope inertia, at the same time the spin axis will begin to precess in a vertical plane and will continue to do so with sufficient power to lift light weights until all the gyroscopic inertia disappears due to the rotor slowing and stopping. The Three Frame Gyroscope. If the base of a three framed gyroscope is held in the hand with the rotor spinning and turned about any of the three axes, the rotor will continue to point in the original direction in space. This property is known as gyroscope inertia. 2, record 63, English, - three%2Dframe%20gyroscope

L'analyse des données provenant des trois encodeurs optiques du gyroscope démontre sans doute qu'au moins un des axes s’est bloqué très tôt au cours du vol. Le gyroscope n’ étant plus libre de pivoter sur trois degrés de liberté, des forces de précession sont probablement apparues, causant des rotations aux axes libres qui ne correspondent pas à des mouvements réels de la fusée en vol. Comme le gyroscope a pu être récupéré, un examen de la structure a été effectué après le vol. L'équipe du Gaul a pu constater que le gyroscope a subi des dommages importants : les cadres externes et internes sont très déformés, l'axe des cadres brisé, plusieurs fils sont rompus et l'encodeur de l'axe des cadres présente une grande résistance à la rotation. 2, record 63, French, - gyroscope%20%C3%A0%20trois%20cadres

A universal joint is a positive, mechanical connection between rotating shafts, which are usually not parallel, but intersecting. They are used to transmit motion, power, or both. The simplest and most common type is called the Cardan joint or Hooke joint... It consists of two yokes, one on each shaft, connected by a cross-shaped intermediate member called the spider. The angle between the two shafts is called the operating angle. It is generally, but not necessarily, constant during operation. Good design practice calls for low operating angles, often less than 25°, depending on the application. Independent of this guideline, mechanical interference in the construction of Cardan joints limits the operating angle to a maximum (often about 37½°, depending on its proportions. 3, record 69, English, - Hooke%20joint

Horizon sensors [are] the primary means for directly determining the attitude of a spacecraft relative to the Earth ... The attitude of spacecraft relative to Earth is one of the most important aspects of attitude determination and control, particularly for communications (TDRSS), weather (GOES), Earth resources (LANDSAT), satellites, etc. Earth cannot be treated as a point source like the Sun, especially for near Earth satellites for which Earth covers about 40% of the sky. Therefore, merely detecting the Earth is by no means sufficient for attitude determination, even for the most crude attitude determination requirements.

Ainsi les axes plate-forme resteront toujours alignés sur ceux des gyros. C’est la notion de plate-forme stabilisée. 7, record 79, French, - plate%2Dforme%20gyrostabilis%C3%A9e
