1 Raytheon is one of the technology leaders specializing in defense, homeland security, and other government markets throughout the world. With a history of innovation spanning 90 years, Raytheon provides state-of-the-art electronics, mission systems integration, and other capabilities in the areas of sensing, effects, command- control communications, intelligence systems, as well as a broad range of mission support services. Our team contributed to a highly mobile robotic system design that consists of a perimeter protection surveillance system, analysis software, and engagement subsystems. By working together we applied Systems Engineering methods to ensure the total system would be functional, producible, affordable, and easily acquired by the customer(s). As interns we learned how to bring a project from concept through design stages culminating in a presentation of our project to Raytheon staff. Our design model incorporated aspects of systems, electrical, and mechanical engineering to develop a system marketable to multiple customers. The presentation of our project includes CAD models, a physical model, and a computer animation to showcase the functionality of the system. We would like to acknowledge the National Science Foundation and MESA programs for providing this opportunity and the MESA staff, Rafael Alvarez, Theresa Garcia, and Eric Pamintuan for all their guidance. We would also like to thank our Raytheon mentors: Randy Cremer, Phong Bach, John Harmon, Phil Benham, Mark Lambert, Rafael Batlle, Tony Pamp, and everyone from our respective units. SDCC NSF Grant # DUE SDSU NSF Grant # DUE Forms of communication were established through multiple trade studies based on factors including signal strength, reliability, cost, and suitability. We then began to categorize inbound and outbound network traffic for the system and sensors into categories based on the priority of the information transmitted. Each category was then assigned to a line of communication based on its given priority.

Describes the characteristics of the proposed system from the viewpoint of a user. It is used to show the flow of communication and system operation. Using Microsoft Project we developed a plan, created a working schedule and were able to assign tasks based on their priority level. A length of fiber optic cable will be our primary communication line between the vehicle and the infrastructure. Fiber optic cable is inexpensive, secure for communications, can span long distances and handle high bandwidths. Multiple secondary forms of communication will also be used (i.e. wireless, line of sight propagation) Based on a Motion Sensor Trade Study, the Piramid XL2V-WC was chosen because it has a dual camera, microphone and is tamper resistant. It also has a large operable temperature range and an adjustable mount. The drawback to this model is the short detection range (90 feet) and the size constraint of the vehicle. Applying similar technology to what was first patented in 1907, our project will be propelled by an electronically controlled linear synchronous motor. To stay within the magnetic scope of design, we also planned for the vehicle to levitate using Maglev technology (i.e. Transrapid train in Germany). Riding on a cushion of air created by a magnetic field and propelling electronically will greatly reduce noise pollution from the vehicle as well as reduce maintenance by removing many traditional friction elements such as wheels and bearings. Unistrut track construction: Two 3 section wide Unistrut tracks, each at 20’ long, with a support bracket every 10 ft. Utilizing consumer off the shelf (COTS) Unistrut and the concept vehicle constraints, we decided that a dual vehicle system running on two separate 3x Unistrut tracks would maximize surveillance abilities. The track will house Maglev electro magnets on the two outside sections of the track while the centre section will conceal fibre optics for infrastructure communications. The vehicle design, incorporating part of the Maglev and linear synchronous motor components, will operate as a base for a multitude of sensors and effectors. Separate power will be supplied to the vehicle by battery pack and capacitor. Regenerative braking and a solar panel, mounted on top of the vehicle, will keep the power-storage devices full. The capacitors will allow pulsed power to be delivered when rapid acceleration is required. The main goal of the final design will be a system that is lightweight, power efficient and cost effective. Stemming from our Operational Concept and research of possible technologies, we compiled a list of system requirements to meet the end user’s needs. These needs drive the project to determine the robot’s performance and capabilities. The system is not complete until all of these requirements have been met. Cumulative scores based on individual features ranked on a scale of 1-3
