SEEDER RB30CR4 robotic crane system features the 4th-generation robotic pan/tilt head with T-shaped structure and new robotic chassis, with an electronic level system as standard. It delivers automated shooting as a broadcast-grade auxiliary camera system for pre-production, suitable for real-scene and AR/VR/XR/MR virtual production in studios and live events.
The telescopic arm ranges from 2.93 m to 4.11 m for flexible length adjustment to match site conditions. Operating noise remains below 35 dB to meet strict professional studio requirements. Shake-free start/stop movement guarantees broadcast-ready footage, and built-in telephoto stabilization delivers steady shots for long focal-length lenses. Powered by AI algorithms, the system generates motion trajectories with up to 16 nodes based on motion time and distance for smooth multi-point curved movement to realise complex camera motions. It tracks the frame centre automatically: when manually controlling the crane’s XYZ axes, the pan/tilt head pans and tilts to lock the frame centre, helping operators compose shots rapidly.
It supports the full lineup of Canon and Fujinon B4-mount full-servo lenses, offering zoom, focus and iris control. AI auto-focus is available during synchronous movement of the crane and pan/tilt head. The system retrieves zoom and focus tracking data via digital lens cables and automatically compensates motor tracking delay according to lens brand for precise synchronization. Adopting black-burst sync, it outputs 23-bit FREE-D tracking data exceeding 8.3 million counts per 360°. Tracking outputs include RS422 serial and directional UDP, with configurable UDP port. Compatible with Vizrt, ZD, Pixotope and UE5 virtual production systems.
Modular design enables tool-free assembly and disassembly, with full installation completed within 15 minutes. Powered by 220 V AC with maximum power of 350 W. Absolute encoders record position and tracking data; the unit is operational within 10 seconds after power-up and requires no startup calibration, making it ideal for studio and live broadcast applications. Standard TCP/IP protocol supports third-party control and automated workflows, compatible with SEEDER SeeArt, Vizrt MOSART, ROSS Overdrive and Grass Valley IGNITE studio automation systems.
Dual safety protection consists of optical collision avoidance and dynamic collision detection. Two optical sensors are installed on both sides of the arm with a configurable 20 cm detection zone. Once obstacles are detected, the system triggers an immediate stop within 20 cm. It also halts automatically upon abnormal motion resistance via dynamic force sensing. Users can set the home position and travel limits. Built-in and external control systems support fast switching, and an emergency stop button is supplied as standard.
The dedicated control software controls crane XYZ movement, head pan/tilt, and lens zoom/focus/iris over the network. It manages up to 8 robotic camera units and stores 32 programmes. Each programme contains 16 sequences, and each sequence holds 16 scenes, totalling 8,192 editable scenes. Sequences support long curved motion and forward/reverse playback. Scene files support import and export, with an independent UI for each programme for quick recall.
