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
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
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.
Parts
Nokia E62
Gumstix with BT
connectivity
(on its way)
ThingMagic’s Mercury 4

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