The technology has been developed by Hovering Solutions as OEM. The small robot is equipped with a fully onboard positioning and navigation system, which is why no external references or beacons are needed for the system to operate. The novel positioning unit is able to estimate the robot’s position, attitude and speed in GNSS(GPS)- and light- denied environment. The navigation unit is totally immune to magnetic field distortions produced by the metal surrounding the robot during the flight.
Total vehicle weighs less than 1.7 kg and the battery lifetime is enough to scan up to 700 meters of penstock in a single flight. With a diameter of 43 cm between motors, the robot is able to fly in autonomous mode through penstocks as narrow as 2 meters in diameter, up to a maximum of 10 meters in diameter.
The inspection operation is carried out with NO pilot, NO radio communications and NO line-of-sight, all of them are crucial factors to accomplish a successful mission in the target scenario.
The system is equipped with a new module named as H-eyes for which a patent has been recently submitted by Hovering Solutions.
This new technology provides outstanding quality on surface information data capture and is able to detect faults and details as small as 1 square millimeter on the penstock’s surface.
In addition, the new H-eyes system improves the robot’s navigation performance and reduces the overall vehicle energy consumption.
