Get Started We'll tell you all you need to know to start evaluating and working with this product. Help find your solution with the Automotive Compilation documentCréation le 24 Novembre 2007 Dernière mise à jour le 8 Aout 20008 I made a software to configure the UAVP under window CE instead of using a laptop. This software called UAVPsetCE, is available at the end of this web page.

Dossier quadrirotors
Préambule : Ce texte est tout public, mais contient des références au modélisme. Des connaissances de base en modélisme sont donc nécessaires. La théorie Un quadrirotor est un appareil volant comportant 4 rotors pour sa sustentation. Les 4 rotors sont généralement placés aux extrémités d'une croix, et l'électronique de contrôle est habituellement placée au centre de la croix. Afin d'éviter à l'appareil de tourner sur lui même sur son axe de lacet, il est nécessaire que deux hélices tournent dans un sens, et les deux autres dans l'autre sens.Qu’est-ce que c’est ? Un quadrirotor est un appareil volant comportant 4 rotors pour sa sustentation. Les 4 rotors sont généralement placés aux extrémités d’une croix. On peut aussi placer les rotors aux extrémités d’une structure en forme de H, mais le principe de base consiste à placer les 4 rotors aux 4 coins d’un carré, sur un même plan horizontal. Le Contrôle Il existe plusieurs solutions pour contrer et contrôler le mouvement de lacet :

ChRoMicro - Cheap Robotic Microhelicopter HOWTO
A number of inexpensive microhelicopters are now available to RC model hobbyists: Ikarus Piccolo, MS Hornet, Carboon, Dragonfly, Honeybee, Hummingbird, Tiny, Aerohawk, Blade CP, Sky Lark... These are essentially scaled-down versions of regular model helicopters, made possible by advances in battery technology. Some models have a rotor head with fixed collective pitch (FP), while others have both cyclic and collective variable pitch (CP).Ever since the PS3 platform was released (Japan: 2006-11-11; USA: 2006-11-17; Europe: 2007-03-23) there has been speculation as to whether its wireless controller, dubbed " SIXAXIS ", could be used in non-gaming applications. It is already known that the SIXAXIS operates as a regular HID device in USB mode. Since it is being marketed as a Bluetooth device, it was fair and legitimate to expect it to also work with any Bluetooth-compliant computer, just like the Wiimote. This document explains how to configure Linux to recognize the SIXAXIS as a Bluetooth HID device.

the Robotics Toolbox for Scilab/Scicos
This is a collection of slides presented at the first HeDiSC Workshop On Open Source Software for Control Systems , which took place in Lugano (Switzerland) at SUPSI-DTI, at the end of June 2009. The presentation consists of two parts and it aims to illustrate features and usage of the Robotics Toolbox for Scilab/Scicos. The first part of the presentation addresses the general problem of rigid motions representation in ℜ³ and also provides detailed examples of how robotic manipulators can be modeled in Scilab.[APP]Pocket GForce [Source code released in p20] Here you go the 1st program to measure how hard you stump against a wall.

Dans le plan, il existe plusieur façon de repèrer un point. Repérage cartésien : on muni le plan d'un repère orthonormal , à tout point M de ce plan, correspond un couple unique (x ; y ) de réels tels que = x + yFlight dynamics
Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space . [ 1 ] It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time. [ edit ] Aircraft Axes to control the attitude of a plane This section focuses on fixed wing aircraft. For other kinds see aircraft Flight dynamics is the science of air vehicle orientation and control in three dimensions.La conception du châssis du Sphéniscoptère doit satisfaire plusieurs critères : Etre le plus léger possible Supporter les vibrations des quatre moteurs et les contraintes de vol Embarquer et protéger l'électronique et les accumulateurs Supporter, orienter et protéger la caméra Servir de support d'atterrissage Plusieurs études ont donc été nécessaires afin d'obtenir un châssis optimal. Chaque composant ou pièces mécaniques ont été pesés.
