The SEEDER RB18Rail rail robotic elevating system is developed for automatic shooting of AR, VR, XR, MR or real scene in various broadcast studios, remote photography, government, education, event live and so on. Features such as anti shake technology, noise reduction technology and AI curvilinear motion technology ensure the shooting of complex motion video and meet every need of professional broadcast television studios.
Fully integrated, highly accurate, smooth motion control in all axes. Precision engineered lifting system makes it possible to raise cameras to the heights while retaining stability and smoothness of on-air control.
Tracks design can be straight or curved, and they are available in various sizes and can be customized to achieve the required min/max length. The stainless-steel materials ensure durability and cost-effective.
Modular design, tool-free assembly and disassembly, 15-minute setup. The system uses absolute encoders for position tracking — no calibration required — making it ideal for both studios and large-scale live events.
The system includes two sets of control systems, namely built-in and external, which can be quickly switched for use. It comes with an emergency operation button as standard. Seamlessly integrates with studio control systems like SEEDER SEEART, Vizrt MOSART, ROSS Overdrive, and GrassValley, supports graphic systems such as Vizrt, ZD, Brainstorm, UE5, and more.
