Project 1 -Navigation and Tracking Using Wi-Fi Signals

Sponsored by SAIC – www.saic.com

Mapping Technologies Initiative Abstract: Mapping Technologies Initiative (MTI) has been tasked by SAIC with developing a tracking system for emergency first responders using Wi-Fi connectivity to provide location data. The system to be developed consists of four primary components: a hand-held device containing a Wi-Fi module, a host application which runs on a server and does the tracking calculations, a database that stores both tracking and room status data and a website that provides the end-user with a visual representation of the tracking data in the database in real-time. This hand-held device is called the Wireless Emergency Response Transceiver (WERT). The Wi-Fi module within the WERT will receive and report RSSI (received signal strength indication) information to the host application over the building’s existing Wi-Fi network. Each room in the building will have a unique set of RSSI trends from the available Wi-Fi access points in range from which the host application will determine the current position of any active WERTs. Once the location is known, status information about that location is sent back to both the WERT and the website.

Project 2 -Pedestrian Position Tracking Using Inertial Sensors

Sponsored by CUBIC Corp.- www.cubic.com

 

Project 2 – Team 1

JAGR2 Abstract: The JAGR2 tracking system tracks a pedestrian using Global Positioning System (GPS) data and inertial sensor data. The system will determine the most accurate position by data compensation and correction. The inertial sensor provides relative data position. The GPS data will provide absolute data position. Given the fact that GPS requires an obstacle free view of the sky, indoor use of this system alone will not provide correct position information. Whenever the GPS data is found unreliable, inertial sensor data will begin to be used. The inertial sensor calculates relative position using gyroscopes, accelerometers and magnetometers which function well regardless of the environment characteristics. The JAGR2 tracking system will also transmit processed information to a computer station for data logging and display. The transmission of this information will be done by using an embedded web server which will send the information wirelessly using existing WiFi networks.

Project 2 – Team 2

GlobalTraC Abstract: This project will utilize the data from a GPS module as well as the data provided by an Inertial Measurement Unit (IMU) in order to track a pedestrian location. Relying solely on one or the other set of data can be inaccurate. A GPS unit can suffer from obstructed satellite visibility, multi-path or atmospheric effects. An IMU is limited by the accumulation of noise error in the accelerometers and gyroscopes. The coupling of these two data sets will provide for seamless tracking; relying on the IMU when GPS data is unreliable, and resetting the IMU with reliable GPS information. This portable, self-powered unit will transmit positioning data wirelessly to a host computer for real time tracking.

Project 3 – Wireless Asset Tracking

guardDog Abstract: The wireless asset tracking modules will be designed to use in a lab environment. Within the lab there will be one base and many nodes connected to the assets they are tracking. The nodes will hold information about each device they are connected to. Each node will transmit this information to the base one at a time. The base will receive information about the nodes and also tell the node when to wake up next. The user will use Lab View to communicate to the base.

Project 4 – Unmanned Aerial Vehicle

Project 4 – Team 1

AEROBOTICS Abstract: In many circumstances it is desirable to have a versatile, inexpensive, autonomous robot available to complete a task. This is most often advantageous when a circumstance presents a danger to human life or when a human is not possible` due to size or maneuverability issues. Our goal will be to create an aerial platform that will be the core for mission specific uses. These uses range from surveillance, mapping, search and rescue, security and more. Military applications are also possible and advantageous due to the low cost of the platform and the life saving possibilities of robotic warfare.

Project 4 – Team 2

AutoFly Abstract: Our objective is to program a microcontroller equipped with the proper sensory array to allow a small helicopter to take off, fly, and land autonomously. The system includes a pre assembled remote control helicopter that will be equipped with the proper sensory and processing equipment. A PIC (Peripheral Interface Controller) processor and a CPLD (Complex Programmable Logic Device) will provide processing and analog to digital conversion of sensory inputs. Infrared sensors and two accelerometers will provide aircraft with orientation and heading data analyzed by the processors. The use of a decisive and creative algorithm will collect that data and help provide feedback to pre- existing servos and motors for correction of flight parameters. The aircraft will be integrated and programmed to run autonomously in a known physical environment by flying to the end of a hall, turning around and landing at the take off location.
