1. Smart Kitchen Mid-Semester Demo March 2nd, 2006 Suppakrit Forbes Chatchayanusorn Charles Christopher Onyeama Nachiket Shelgikar Saravana Sivasankaran http://www.ece.cmu.edu/~ece549/spring07/team6/index.html

2. Project Concept System – Smart phone/ PDA with Docking Station – RFID reader reads tags off the products and updates the ‘status’ of the kitchen. – Smart phone/ PDA generates a shopping list based on ideal stock and current kitchen status Assumptions – All the products will be RFID tagged replacing currently used UPC Barcodes

3. Architecture Block Diagram RFID sensors detect the tags using RF and sending data to CPU via Ethernet interface CPU shall handle the database immediately CPU shall wait until the device requests data and starts synchronize via Bluetooth interface

4. Status Update We finally found a RFID reader and an antenna to work with (phew!) Able to communicate with the reader through a laptop. We can get the information we want. Developed a simple Phone GUI. Not synchronized to take files received through Bluetooth. But the file can be read as a document in the phone.

5. Parts Sensormatic Antenna * ThingMagic’s Mercury 4 RFID Reader * Gumstix with BT connectivity (on its way) *Thanks to Burcu Akinci for letting us borrow the kit Nokia E62

6. Mid-Semester Demo Antenna reads products Send data to reader Transmit tag id and other data via Ethernet Transmit list via Bluetooth

7. Next Steps Get the gumstix soon (fingers crossed) Work on implementing Bluetooth connectivity via C. Get writeable (smaller) RFID tags Look into possibly getting another RFID reader to keep track of things that are disposed in the kitchen.

8. Software Architecture

9. Lessons Learned Be weary of projects that require expensive equipment. (Unless..) Don’t believe everything on the box. (Range issues) Tech support are some of the biggest helps you can get. Some things just don’t work together (quite literally)

10. Tentative Schedule WeekMilestones Mar 2 nd – Mar 9 th Look into possibly getting another RFID reader Mar 10 th – Mar 16 th Spring Break! (Brainstorm on an 18-549 logo) Mar 17 th – Mar 23 rd Start programming on GUMSTIX Mar 24 th – Mar 30 th Edit tags to store information we want Mar 31 st – Apr 6 th Develop GUMSTIX application that sorts grocery lists Apr 7 th – Apr 13 th Improve on Phone GUI Apr 14 th – Apr 20 th Automatic and manual synchronization between phone and GUMSTIX Apr 21 st – Apr 27 th Work on any remaining unsolved issues Apr 28 th – May 4thPrepare for final demo!
