Flyability Elios UAV


Carrying its own protective frame, the Elios from Flyability is the first collision-tolerant UAV (drone), designed for the inspection and exploration of the most inaccessible places. This means you can access the tightest spaces without any risk of crashing. No need to focus on avoiding obstacles, Elios bounces off and rolls on them to find its way. You can fly close to or even in direct contact with humans without any risks of injuries.

*An SFOC is not required for indoor operations.  The new 900 series Canadian Aviation Regulations do not apply to indoor operations. Once the new CARs come into force on 1 June 2019, there won’t be any new requirements for operating your drone indoors.

OVERVIEWElios, expand your reach

Discover the first collision-tolerant drone, designed for the inspection and exploration of the most inaccessible places. Allowing for the first time to fly in complex, cluttered or indoor spaces, Elios unleashes the potential of UAVs in numerous applications where their use was previously too dangerous or simply impossible.

Elios is made to be dust and splash resistant, operational in environments between 0°C and 50°C, and mistake tolerant so that it can be easily piloted by everyone. Operational after a few hours of training, your personnel will quickly get up to speed with their piloting skills. Designed to fly indoors where few or no drone regulations apply, Elios will be smoothly integrated into your workflow.


Improve Safety

By enabling remote visual inspection in any indoor environments, Elios prevents the need for workers to enter hazardous places or face dangerous situations.

Reduce Downtime

Elios is deployed and ready to gather visuals within a minute. Performing an entire inspection is no longer a matter of days but hours.

Lower Cost

Scaffolding, rope access, or crane are no longer needed to perform visual inspections. Elios gathers visuals of the most complex and cluttered spaces for you.



Inspired by the ability of insects to keep their stability after an in-flight collision, the flight concept of Elios is the result of hundreds of millions of years of natural evolution. Using a unique and pragmatic approach, Elios solves the biggest challenges of flying drones indoor in complex and confined spaces or in contact with humans: the risk of collisions and injuries. Prioritizing tolerance to collisions over the attempt to sense and avoid obstacles, Elios provides the level of reliability that is expected by professionals operating in environments where failure to operate is not an option.

Protective Frame

Carrying its own protective frame, Elios is collision-tolerant. This means you can access the tightest spaces without any risk of crashing. No need to focus on avoiding obstacles, Elios bounces off and roll on them to find its way. You can fly close or even in direct contact with humans without any risks of injuries.

The protective frame of Elios is no ordinary one. It is decoupled on three axes from the inner frame – the drone – using a gimbal mechanism. This ingenious decoupling mechanism is what allows Elios to remain stable in the event of a collision.

Patented by Flyability, the protective frame is a unique and pragmatic approach to flying indoors, in complex and confined spaces and in contact with people. Discarding the need to sense and avoid obstacles, you can start inspecting and exploring – without waiting – the hardest places to reach.

Elios' protective frame is made up of carbon fiber covered with a soft coating. It can sustain collisions, evenly, all around the drone at a speed reaching up to 4 m/s.

Built with modular subcomponents it eases the maintenance process and offers openings large enough to fit one's hand and access the battery container or SD card compartments.

Spherical, the protective frame comes in one size only. With a diameter just below 400 mm, it is slightly smaller than the smallest standard manhole.

Full HD Camera

Elios two-thirds shot, right

When flying in contact with a surface, Elios can gather close-up images with a sub-millimeter resolution of 0.2 mm/px.

The camera video stream is recorded on board, on an SD card housed in the payload head. It is also streamed to the pilot at a lower resolution.

The Full HD camera offers a resolution of 1920 x 1080 at 30 frames per second and performs well in low light.

Automatically corrected by default, the Exposure Value (EV) of the captured images can also be remotely adjusted, from the ground station.

Thermal Camera

Seeing beyond what a human can see may be crucial in many cases. Detecting a crack that is invisible can help to anticipate potential major degradations. Detecting a body in very poor lighting conditions can simply save lives.

Flexible Vision

Mounted on a rotatable head the cameras can capture images looking above and below the drone. The full HD camera offers a total field of view of 215º and a horizontal field of view of 130º while the thermal camera offers a total vertical field of view of 42º and a horizontal field of view of 56º.

On-Board Lighting

When inspecting and exploring pitch dark environments the onboard LED lighting system becomes very useful. Preventing the need for any additional external lighting, it lights up the scene in all the directions you may be looking.

The intensity of the 5 arrays of high-efficiency LEDs providing even lighting in front, top, and bottom of the robot, can be adjusted remotely using the ground station.

When changing the pitch angle of the camera head, the light beam is adapted, always providing the right lighting.

Worker holding EliosWireless Communication

Elios is equipped with a cutting-edge wireless communication system that provides a live video feedback allowing the pilot to bring the drone to the most inaccessible places up to multiple hundreds of meters beyond line of sight.

The wireless communication system offers a robust digital, bidirectional, long range signal transmission which includes a video and data downlink – from the UAV to the Ground Station – and command uplink – from the Ground Station to the UAV. Thanks to a partnership with DJI, Flyability has integrated the Lightbridge 2 to the drone and can rely on state of the art transmission technology.

Using the 2.4 GHz frequency band, the wireless communication system does not require any special authorization to operate and preserve its high-quality even in the most complex and confined spaces. For example, it is possible to fly Elios over 100 meters above the ground in a closed boiler with the pilot safely standing outside next the entrance manhole.

Ground Station

Elios Ground Station is composed of a remote controller, a tablet and a purpose designed ground control application providing the pilot with live telemetry data, an SD live video stream captured by Elios, and the information and controls that you need to operate it efficiently and safely.

In addition to displaying the live SD stream received from the drone, Elios Cockpit displays live telemetry data, gives you access to a detailed status of your drone and let you adjust settings right from the application.
