Microcopters And Ground Robots Used To Save Earthquake-hit Italian Churches

By

In late July the EU-funded project NIFTi successfully deployed a team of flying and ground-based robots in Mirandola, Emilia-Romagna, Italy, upon the official request by the Vigili del Fuoco, the Italian national rescue organization in charge of disaster response and recovery. The NIFTi team was tasked to assess the damage to local churches only 20 kilometres away from the epicentre of the series of earthquakes that hit the region in May and June 2012.

When the NIFTi team started their mission, the inner city of Mirandola was still sealed off by the military and nobody could access the area without authorisation. The conditions were very dangerous, and two fire fighters had been killed there before by a collapsing roof.

The robots entered badly damaged buildings, scanned the area and produced 3D map reconstructions and high-resolution videos to report on structural damage to ceilings, arches and aisles in the largely destroyed churches, which date back to the 13th and 15th centuries, and on the state of cultural artefacts such as paintings, decorations, tombs and altars.

The team of robots and people had to work in harsh conditions, with no electricity, using a power generator, and flying the aerial robots in the dust, with almost no visibility, in temperatures of 36–40 C. The ground robots were hindered by piles of rubble.

NIFTi deployed a team of seven people, two tracked ground robots and two microcopters. The NIFTi team received essential support from members of the Vigili del Fuoco. Five microcopter missions were flown at the Chiesa di San Francesco d’Assisi and four at the Duomo in Mirandola. T

he ground robot entered the Chiesa di San Francesco d’Assisi twice, to provide video and a 3D reconstruction of the western gallery. It also ran several missions in the Duomo (two in the eastern aisle and one at the top of the western aisle). The ground robot was operated by a five-person team from a remote command post, involving a pilot, mission specialists, and an in-field observer. At the Duomo the microcopter’s tasks included flying over the inaccessible main aisle.

All the robots used during the mission were developed by the NIFTi project. It is a concrete example of human-robot teamwork in complex deployments.

The assessment team was co-led by DFKI (Saarbrücken) and the University La Sapienza (Rome), with the support of the Italian Ministry of Culture.
