Using Microsoft Project we developed a plan, created a working
schedule and were able to assign tasks based on their priority
level.
Our team contributed to a highly mobile robotic system design that
consists of a perimeter protection surveillance system, analysis
software, and engagement subsystems.

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.

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.

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.
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).
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.
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)
SWOT Analysis for Infrastructure identifies internal and
external factors to help specify objectives for the project.
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.
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.
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.
