Tasks Performed
G.R.O.B.I. Project
• Finished Python tutorial (Eldridge)
• Finished accelerometer test board (Kristi)
• Designed cell phone user interface for
GIZMO truck (Eldridge)
• Worked on final circuit board design for
GIZMO truck (Kristi)
G.R.O.B.I. Project
PCB Design
• Made custom device
libraries for bluetooth
module & ATmega164p
• Through-hole
components => mostly
routed on the back (blue
traces)
– Also reduces problems
due to no through hole
plating
• Stacked bluetooth
module & microcontroller
to save space
• Uses modular
accelerometer board
• External clock source
Python for S60
G.R.O.B.I. Project
• Write Python applications for cell phones with S60
platform
• About S60 Platform:
- Allows software on cell phones to run
- Provides full-color user interface
- Includes software to combine features
of a mobile phone and PDA
- Examples: e-mailing, browsing,
calendar, data transfer

Python for S60 (cont.)
• Advantages of Python:
- open source
- object oriented
- extensive standard library
- modules can be extended using C or C++
- applications can be written quickly
• Additional Advantages of PyS60:
- can create standalone applications
- additional modules to access cell phone functions
like camera, audio, and Bluetooth communications
G.R.O.B.I. Project
Example Python Applications
Creating menus
Reading user input
Drawing canvas
Detecting key press
