Challenges for Expeditionary Robotic Manufacturing Systems

The ability to manufacture spare parts, complete repairs, and carry out other important manufacturing activities is a major concern for users in expeditionary environments (battlefields, remote research stations, or disaster relief areas). The challenges that arise include a limited source of energy, security concerns, an unreliable supply chain, poor local infrastructure, harsh weather, and urgency not typically encountered in regular manufacturing environments. This article developed a conceptual model for the challenges encountered in expeditionary manufacturing, with a focus on applications that use robotic systems to complete or assist in the fabrication. A case study was completed to demonstrate the concepts for a realistic scenario. This work is useful for designers and system planners who wish to use robotic systems (including CNC machines and 3D printers) to support manufacturing activities within an expeditionary environment.
