Title
(EN) APPARATUS AND METHOD FOR LOCATING AN OBJECT
(FR) APPAREIL ET PROCEDE DE LOCALISATION D'UN OBJET
Abstract
(EN)
A number of examples of apparatus for locating an object on a platform. Such apparatus is useful in automated manufacturing equipment. In each example, the platform is arranged to secure objects and is mounted for vibration. Inertia quantities are calculated from inertia measurements and used to calculate the orientation of the object. In the preferred example, a platform (35) is mounted for vibration about an axis (15) and driven into a set of rotational positions by a motor (27). Vibration frequency is measured in each position and used to calculate an inertia quantity. The position and orientation of an object on the platform are calculated from the inertia quantities.

Plusieurs exemples sont décrits pour localiser un objet sur une plate-forme à l'aide d'un appareil. Un tel appareil est utile dans une installation de fabrication automatisée. Dans chaque exemple, la plate-forme est agencée pour fixer des objets et est montée de manière à vibrer. Des quantités inertielles sont calculées à partir de mesures inertielles et sont utilisées pour déterminer l'orientation de l'objet. Dans l'exemple préféré, une plate-forme (35) est montée en vibration autour d'un axe (15) et est entraînée dans un ensemble de positions de rotation à l'aide d'un moteur (27). La fréquence des vibrations est mesurée dans chaque position et est utilisée pour calculer une quantité inertielle. La position et l'orientation d'un objet se trouvant sur la plate-forme sont calculées à partir de quantités inertielles.
