The Kraken - drone based data aquisition

Drone technology has been rapidly emerging. However, in the commercial sector where drones tend to operate with a payload of one sensor at a time only, there is a need to enable multisensor surveying. To reach this versatility, we introduce the ultimate heavy lift capable drone “The Kraken“ octocopter drone.

The Kraken is a redundant and customisable multicopter with a maximum thrust of 100kg produced with all 8 motors combined. The Kraken is completely designed with state-of-the-art CAD (Computer-Aided Design) programs, CNC (computer numerical control) machined with the strong and light weight materials, and assembled completely in house with skilled engineers and technicians to the highest precision. 

The Department of Exploration at the Helmholtz Institute Freiberg has specialized on drone based data acquisition with various payload categories. The Kraken is made for multi-payload survey missions and has been deployed in 2020 for various field works in Germany and abroad, with various sensors, e.g. hyperspectral camera, magnetometer, infrared thermal camera, short wave infrared camera and a few more sensor that are currently being tested.
