A system for robotic construction of a marine vessel includes a gantry and a robot interface connected to the gantry, the gantry configured to transport the robotic interface in at least two directions. A robot configured to perform a construction operation is releasably coupled to the robot interface. A robot controller is disposed on the robot and is configured to operate the robot. The robot controller remains with the robot when the robot is removed from the gantry. A controller is operably connected to the gantry and the robot interface, the controller configured to position the gantry and to attach and release the robot from the robotic interface.
