Veracity-Steuerräder für Gimbal-Betreiber mit RC-Sendern
12 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Steuerräder verbinden sich mit RC-Transmitter-Trainer-Ports und wandeln den Dreheingang in digitale Datenströme um, die Joystick-Signale für den Gimbal-Betrieb ersetzen.
- Die Veracity-Räder fügen keine Systemlatenz hinzu, da die gesamte Verarbeitung innerhalb eines einzigen Datenpaket-Herzschlag-Zeitrahmens erfolgt.
- Die Genauigkeit von Gimbal hängt von den eigenen Sensorfunktionen des Gimbal ab, nicht von der Steuerschnittstelle, da Gimbals wie das Movi Gyro-Feedback ohne direkte Positionsrückmeldung auf Kameraachsen verwenden.
- 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.
Hängt ab von
- 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.
