With a spherical cage protecting propellers from impacts, Elios 2 remains always stable through lightning-fast corrections on the propellers’ speed and direction of rotation. The entire payload is mounted on a retractable structure that protects it from damages in case of frontal shocks.

With an overall dimension just below 40 cm (15.7 in) Elios 2 fits into standard manholes and can enter any space where an inspection is needed. It can safely and easily be flown into assets without any human access needed; at no point do workers need to enter the space during the inspection.
