    Research & Development

 

 



With the BMBF-funded research project TAMMOS, topocare and FHDW  are exploring new forms of mobile flood barrier construction. The results are already forward-looking in many areas.

Due to the professional exchange with the Fire Brigade Association Rhineland-Palatinate, which set up the project related Advisory Council for Flood Protection, knowledge and practical experience with the river Rhein and Mosel is available for the project.

The project is part of the research program Research for Civil Security of the Federal Government, where solutions for mitigation and crisis management are developed.

Autonomous flood protection

The aim of the project is the creation of systems and procedures for mobile flood protection in high-risk areas, which are under threat of flooding.Machines should be capable of  driving independently into the risk area and build up a protection wall with the help of sand-filled geotextile hoses, the topotubes.

In order to achieve this, we are developing a machine for semi-autonomous laying of geotextile tubes (topoRobo). Furthermore, small logistics units are developed, which bring the sand to the laying machine and feed it continuously (topoAnt).The general procedure for laying the flood protection tubes is as follows:

  • The topoRobo drives to the starting point of the installation
  • As like an ant colony, several topoants move back and forth between the sand and the depot to provide the topoRobo with sand

  • The topoRobo builds the topotubes with the sand from the topoAnts

In order to enable an autonomous process, which is supervised by the operations center (therefore: partially-autonomous), some preparation work beforehand is necessary, which are presented below.


Step 1)


3D-Mapping mittels Drohne

The deployment environment is little known as opposed to autonomous driving on roads. To gain precise environmental data, the area is first explored with a drone. Using photogrammetry, the terrain profile with its highs and lows can be captured, resulting in a 3D map of the area of application.

Photogrammetry is remote sensing in which photographs can be used to depict a three-dimensional shape of the landscape. For this purpose, the drone flies in a grid formation over the reconnaissance area, where photographs are taken at regular intervals.

Due to the overlapping of the photo recordings and shifted viewing angles of the individual photo positions, a three-dimensional map can be calculated.
