Absolute silence is required

The universally usable camera robots in the 320 square-metre studio are based on a very powerful six-axis industrial robot made by the company Stäubli. The solution for the broadcasting organisation enables the director to choose from an almost limitless variety of camera shots in real-time use. The ceiling is 7 metres high, whereby the three robots are suspended at a height of 3.50 metres above the ground. To keep the noise of camera movements to the low level required, the linear rails as well as the steel beams to which the axes are attached must be extremely rigid. "Apart from the absolutely quiet movement of the cameras, the avoidance of vibrations that could affect the picture quality must also be ensured at all times", says Dipl.-Ing. (FH) Fabian Kaiser, the responsible project engineer of Camerobot Systems GmbH, in clarification.

In order to guarantee functional reliability over the long term, shielded control cables which come from the chainflex® product range of igus® and are suitable for energy chains are used in the camera robots as well. This is because a primary aim is to avoid shield wire breakages that can lead to short circuits or reduce the shielding effect. This is prevented by, among other things, the tough braided shield of the chainflex® cables, which have been specially developed for use in energy chains. The shield also protects the twisted-wire binder against torsional forces.
 
The requirements for the production of news programmes are very high in Germany. The camera robots from Camerobot Systems make an indispensable contribution towards correct and appropriate presentation of the contents. The energy supply systems from igus® safeguard the long-term operational reliability and safety of the robots, while also ensuring quiet operation at all times.
