[L’industrie c’est fou] Boston Dynamics’ four-legged robot Spot becomes construction inspector

It is often said that the dog is man’s best friend. It could well become that of building professionals. On the site of a real estate program developing 86,000 square meters of floor space over 10 hectares in St-André-lez-Lille (North), the Spot robot, designed by the American company Boston Dynamics, evolved among the workers during a test phase. He had been seen on an oil platform in Norway, here he is now going for a job interview. Overcoming obstacles, climbing stairs, walking on welded mesh … so many challenges that the quadruped has met with flying colors, according to Bouygues Bâtiment Nord-Est.

Ultimately, the goal is “To integrate the BIM model into his program and let him walk the site in complete autonomy to 3D scan the structures. These readings will make it possible to monitor the progress of the site in real time and with great precision ”, explains the company, which worked in collaboration with the teams of the Construction 4.0 industrial research chair, which combines the Ecole Centrale de Lille (Nord) and Bouygues Construction. The idea is also to carry out 3D scans of spaces that are difficult to access or dangerous for staff, as well as to detect faults thanks to its numerous integrated sensors.

Programmable inspection missions

The robot can take 360-degree photos and videos, and collect information in 3D data that can be linked to digital twins. Autonomous missions can be scheduled. Capable of carrying payloads of up to 14 kg, it is also capable of carrying out topographic surveys.

In Canada, in 2020, a construction company started using Spot. “A robot that will move around the site to take photos at predefined locations with a camera connected to HoloBuilder, a documentation platform that allows comparisons to be made with virtual design and construction software”, explained at the time Pomerleau, which also intended to take the opportunity to assign its teams to tasks with higher added value. Tests had already been carried out in Japan.
