Flying construction robots face first real-world tests

Flying construction robots are undergoing their first tests outside of the laboratory at the DroneHub, based in Switzerland at the Swiss Federal Laboratories for Materials, Science and Technology.

Aerial Additive Manufacturing Research

The research is focused on the use of drones for mid-air material deposition, a process known as Aerial Additive Manufacturing (Aerial AM). Early-stage demonstrations of Ariel AM have showcased capabilities such as rapid on-demand repairs and modular assembly techniques.

The technology is still in its infancy. Challenges impeding further advancements include material durability, localization systems for outdoor environments, and coordination among multiple aerial units. Research to date indicates that the technology can improve productivity and environmental sustainability, providing access to elevated heights, hard-to-reach areas, or hazardous locations, while minimizing waste and energy consumption.

Unlike conventional construction techniques and ground-based robotic systems, aerial robots operate in an unrestricted work envelope. This capability allows them to construct in greater heights and challenging terrains that are inaccessible to ground robots.
