The Aerial Robotics Cooperative Assembly System (ARCAS) is a EU funded robotics project that develops autonomous flying robots to perform tasks too dangerous or otherwise difficult for human workers. It will be the first cooperative autonomously flying robot system to be used to build and disassemble constructions.

In this first year, new aerial robots (helicopters and quadrotors) with multi-joint arms have been developed, and the first control methods have been implemented.
