The collision-tolerant drone for indoor inspections

ELIOS is specifically designed for difficult inspections inside industrial plants and other complex environments. With its innovative protective frame, ELIOS can be used for inspections even in areas which are almost impossible to access, such as tanks, boilers, pipelines, vessels or Silos.The indoor drone can enter a DN400 manhole to deliver images up to 0.2 mm/px.


The flight system is completely manufactured in Switzerland and is particularly suitable as a working tool for applications in cramped parts of industrial plants that are hazardous to humans. By combining a high-resolution camera with a thermal imaging camera, ELIOS can quickly and easily locate damaged spots.

The ELIOS flight system is ideal for professional inspections of industrial plants, energy systems and other technical buildings. It allows cost-efficient and safe inspection flights in areas that are hardly accessible. Providing flight times up to 10 minutes, ELIOS is highly suitable for complex inspections. Batteries can be exchanged within seconds with the result that the UAS is ready to fly again immediately.


The protective frame made of carbon fiber facilitates the inspection even of narrow pipelines, tubes or sensitive surfaces without causing any damage.

ELIOS is manufactured entirely in Switzerland. The flight system is available in an economical ready-to-fly package and can start and land in almost any environment. Thanks to its light construction, ELIOS is easy to transport.


ELIOS is equipped with a high-quality full-HD camera for photo and video recording as well as with a FLIR thermal imaging camera. Even in complete darkness assisted by a LED lighting system ELIOS delivers pin sharp images. The integrated thermal imaging camera facilitates the identification of damaged spots.



Light weight, very stable, safe: The spherical housing makes ELIOS a robust tool that can fly very close to structures.

DN 400


ELIOS is able to access tubes even with diameters of only 400 mm. This makes it possible to inspect difficult to reach parts of industrial buildings without any risk to humans.



ELIOS’ LED lighting system delivers high-resolution images even when used in complete darkness.
