Abstract

Multi-agent systems can be a viable choice for realizing self-organizing systems consisting of reconfigurable software components. We present a real-world system consisting of heterogeneous air and ground robots whose behavior and coordination is orchestrated by a MAS in a decentralized manner. The system is able to cooperatively transport largescale measuring equipment and is used for environmental observation, such as in-situ measuring of temperature.

Description

We successfully took part in ScaleX 2016, a geographical measurement campaign, were our system was used to cooperatively carry a fragile fiber optical cable for distant temperature sensing (DTS)

First measurement results

The following figure shows the measurements of the DTS system, i.e. the temperature measured along the glass fibre, during a single flight. It is possible to clearly distinguish the measurements before takeoff, during flight and after landing. During flight in roughly 20m height, the temperature decreased by 2-4° compared to ground level.

The figure below shows the measurements of the "cube" module on each quadrocopter. A similar ground-air temperature difference can be observed, although the initial temperature is a few degrees higher. This can be caused by sun radiation which heated up the cube modules.
