Roues de commande de véracité pour gimbal opérateurs utilisant des émetteurs RC
Il y a 12 ans. Le matériel et les prix ont peut-être changé depuis.
Ce que le fil a révélé
- Les roues de commande se connectent aux ports d'entraînement d'émetteurs RC et convertissent l'entrée rotative en flux de données numériques qui remplacent les signaux de joystick pour le fonctionnement gimbal.
- Les roues Veracity n'ajoutent aucune latence du système parce que tout le traitement se produit dans un seul paquet de données rythme cardiaque.
- La précision Gimbal dépend des propres capacités du capteur gimbal, et non de l'interface de commande, puisque gimbals comme le Movi utilisent la rétroaction gyro sans retour de position directe sur les axes de la caméra.
- An open-loop system like the Jimmy Jib cannot maintain precise wheel-to-camera relationships because there is no feedback about actual camera position or movement, only torque limiting.
- Achieving exact wheel-to-camera axis relationships requires closed-loop servo systems with encoder or resolver feedback mounted directly on individual axis drive trains, which are heavier and more expensive.
- The Veracity design prioritizes precision through hand-machined wheels instead of off-the-shelf components, adjustable counterweights for balance, and high-resolution encoders to create better operator feel.
- Sensitivity adjustment knobs on individual wheels scale output independently, and a zero button allows wheel offset to match the RC transmitter's zero reading.
Dépend de
- Gimbals like the Movi cannot provide the same precision coupling between wheel and camera as high-end heads with direct encoder feedback because they lack position feedback on camera axes.
- System latency varies by RC transmitter model, ranging from as low as 10ms to much higher, which affects overall control responsiveness.
- The Veracity system was designed for operators who prefer traditional geared head feel over RC joystick operation and will perform differently depending on gimbal type and settings.
- Comparisons to other third-party systems like Hurricane wheels and Bartech focus interface systems were mentioned but not thoroughly evaluated in the discussion.
