Researchers in Germany are developing a submarine robot with specialist sensors (writes Nick Flaherty).

The Bionic RoboSkin project, supported by Germany’s Ministry of Education and Research and led by EvoLogics, is developing a compound fabric that is fitted with sensor elements and water-resistant connectors to supply the sensors with power and transmit the data to the water’s surface.

Researchers from Fraunhofer IZM are integrating sensor modules so that the AUV, modelled on a manta ray, can detect the proximity of objects and ‘see’ and analyse their surroundings.

The permeable and therefore pressure-neutral fabric skin is fitted with touch, flow, motion and position sensors. This textile skin is then pulled tight over the robotic fins.

The case itself works as a conductor by creating the mechanical and electrical contact with the sensor skin itself. Tiny hooks on the sensor module itself snap together to form an easily detachable/attachable interface. The resulting system is modular to allow easy reconfiguration.
