NBC Camera Robotics System

Ray Lowe

The robotic camera-control system described is based on XY tracking, which solves the problems of cable management and positional feedback. A compact, lightweight scissor mechanism controls camera height, permitting the full range of height movement of a standard pedestal. The system is designed for single-operator control of four cameras. Fluid-damped joysticks position and trim the cameras. A data tablet allows the operator to control the system by pointing with a pen. The cue computer provides rapid system configuration from a floppy disk and reconfiguration via user-friendly menus. Safety problems were solved by use of a multilevel system that includes a surveillance camera, infrared proximity sensing, and current limiting of motor drives. Future expansion will allow interface with other automation systems. A computer, controlling robotics, cart machines, switcher, and graphics devices, gives the potential for single-operator management of an entire show from an event list. Automatic talent tracking and framing devices, which will enhance the system's use in more complex show formats, are being developed.
