Project Goal To utilize a positioning system that can be used in an indoor environment and incorporate a completely web based user interface. Cory

Requirements & Specifications Environment To be used in an indoor setting Operational temperature range between -20°C and 50°C Should be of “industrial strength” for use in a typical manufacturing setting Range Cover a minimum area of 50m x 50m Cory

Requirements & Specifications Accuracy Tolerance to within a one meter radius User Interface Operational on any standard PC Able to view data for each object Positional information should be accessible over a standard network No application software need be installed Cory

Requirements & Specifications Installation Should be easily performed by in-house staff Reliability / Maintenance Will be as reliable as the network infrastructure the system resides on Indicator LEDs shall be available Mobile units must be operable for a minimum of twelve hours of battery power Rylan

Requirements & Specifications Cost The prototype shall cost no more than $1000 High volume production units shall cost no more than $500 Physical Attributes No larger than 150mm x 150mm x 300mm Weigh no more than 3kg Resistant to air particulate and moisture Rylan

Engineering Approach Design and manufacture a positioning system using wireless routers as reference nodes This method would allow us to easily deploy a positioning system using an existing WiFi (802.11) network We developed a design for a directional antenna capable of triangulating position information by calculating carrier wave intensity emitted by the routers Herb

Engineering Approach Carrier signal is very “bursty” in nature Intensity Calculations Bit error Signal strength Herb Bursty Bit error rate Intensity

Engineering Approach Employ the Chipcon CC2430 microcontroller utilizing the ZigBee protocol (802.15.4) to determine ranging using intensity calculations Lower cost Increased scalability Smaller infrastructure footprint Herb

Project Tasks Develop and test positioning routines for mobile and stationary units Design a communication interface between the Chipcon hardware and the Rabbit microcontroller (Serial Peripheral Interface or SPI) Convert Chipcon data into a manageable standard and format as extensible mark-up language (XML) Herb

Project Tasks Design and program a custom XML streaming data server Multiple TCP/IP connections Must accept and interpret inbound XML data Must format and stream outbound XML data in real-time to all listening connections Compatible with the Ethernet enabled Rabbit microcontroller Rylan

Project Tasks Develop a platform independent web based graphical user interface (GUI) Authenticate the user Establish a connection to the XML streaming data server Receive and parse the incoming XML data to be displayed to the user in real time Send commands and XML data to the server Rylan

Project Tasks Design the circuitry for the root, specialty reference, and blind nodes Design and construct printed circuit boards Install components into demonstration enclosures Rylan
