Mobile interface - first version

The first version of HYPERION's mobile interface is ready and has been distributed to partners for experimentation. For now, the mobile interface communicates with the drone via a simple UDP-based protocol.

To test communications between the mobile interface and the drone, a dummy server has also been created which implements the communications protocol and gives dummy responces to interface commands.

Thermal examination of photovoltaic panels

All photovoltaic plants where examined with the use of a thermal camera in order to manually identify panels with hotsports and other problems.

Indicative color-coded thermal images of photovoltaic panels with hotspots are shown in the following photos. Yellow colored areas are areas with higher temperatures.

Desktop interface - first version

The first version of HYPERION's desktop interface has been delivered by Pygolampis and distributed to the other partners for experimentation. The current version allows entry of the photovoltaic plant's electrical circuity (e.g. which panel belongs to which inverter and which string). Ir also allows the definition of "obstacles" (dangerous areas for the robot to avoid) and the definition of preset drone poses.

The images bellow showcase some of the functionality of the current version of the desktop interface.

Mapping algorithm experiments

Initial tests of the localization and mapping algorithms were curried out in two photovoltaic plants. Data were gathered using an off-the-shelf drone equipped with two embedded PCs for online computation and a variety of sterescopic camera setups.

Indicative results are shown in the pictures bellow. More information will be provided in deliverable D3.1 (Mapping and localization)
