The US Department of Homeland Security and Robotic Research LLC of Maryland, are building a library of compatible 3D parts that can be used for search and rescue robots. The objective is to have a system in place so that parts can be quickly made to suit any disaster scenario. So when a bot needs to replace a gripper arm with a cutting arm in order to work its way through fallen debris, the arm can be quickly built and integrated into an existing bot.

Two main prototypes have already been developed as part of the program: a small rolling bot called TOSR (Throwable Orientation Switching Robot) and a hexarotor called RAPTR (Remote Aerial Payload Transport Robot). Both bots were 3D printed with the same kind of durable plastic used for interior car parts. They also share core components that are interchangeable, so motors, sensors and controllers can be easily swapped out.
