Kin Chin Chua - Design Notebook
Week of Sept. 05, 2011
Sept. 07 (Wed):
- attended kick-off meeting
Week of Sept. 12, 2011
Sept. 16 (Fri):
- attended weekly meeting
Week of Sept. 19, 2011
Sept. 21 (Wed) ~1.5 hour :
- participated in teleconference with HKUST
Sept. 23 (Fri):
- attended weekly-meeting
Week of Sept. 26, 2011
Sept. 28 (Wed) ~1 hour:
- attended group meeting:
- Designed and drew a block diagram for the control system.
- Discussed about some processors and TI microcontroller.
Sept 29 (Thurs) ~1.5 hour:
- Looked over the TI microcontrollers with Arm cortex M3 processor suggested by Scott and Jason
- Searched online for other microcontroller board such as Arduino Fio.
- Found a webpage introducing a similar project (WIFI Robot) and thought it might be a good reference
~ Instead of internet, the robot was controlled by the user by connecting a laptop to the router mounted on the robot wirelessly.
~ It also has video feed, so that the robot can be controlled even it is out of sight.
Sept. 30 (Fri):
- attended weekly-meeting
Week of Oct. 3, 2011
Oct. 6 (Thurs) ~2 hours:
- attended group meeting
- Designed a draft of poster for VIP poster session
Oct. 7 (Fri):
- attended weekly-meeting
Week of Oct. 10, 2011
Oct. 14 (Fri):
- Search for some network cameras that might be useful such as: (~1.5 hours)

~ http://www.brickhousesecurity.com/vivotek-pt7137.html
~ I found that some cameras are not bad but too expensive.
- attended weekly-meeting
Week of Oct. 17, 2011
Oct. 18 (Tues) ~3 hours:
- attended group meeting
- decided to take a tank as the vehicle platform as it has more space for us to put things on
- decided on wireless transceiver
- decided to use push buttons and IR sensors to counter the situation might happen when there is a delay on receiving video.
- some difficulties are encounterred while deciding to use an IP or network camera such as:
~ it is difficult to feed the video to our server since specific software or webpage is required for most of the IP cameras
~ ip address of an IP camera has to be assigned manually
- We also tried to program the microcontroller board and we managed to print our names on it.
Oct. 19 (Wed) ~2 hours:
- met with the group to set up a lab bench in EE63
- attended VIP poster session
Oct. 20 (Thurs) ~ 1.5 hours:
- Read the reference manual of the microcontroller board we are using
- Read more about the terms like A/D, PMW, SPI, UART, etc.
Oct 21 (Fri):
- attended weekly-meeting
Week of Oct. 24, 2011
Oct. 25 (Tues) ~3.5 hours:
- attended group meeting
- tried to search for some useful cmos cameras
- realized that the transfer rate of a cmos camera is too high (about a few Megabytes/s)
- task: try to find for cmos camera that would output M-JPEG or M-PEG
- wrote a list for all possible peripherals and interfaces which would be needed for the project
Oct. 28 (Fri):
- tried to search for cmos camera that would output M-PEG or M-JPEG but didn't find anything useful. There are quite a few IP cameras that output M-JPEG though. (~1 hour)
- attended weekly-meeting
Week of Oct. 31, 2011
Nov. 2 (Wed) ~ 45 minutes:
- continue working on the draft of the list for design review made by Scott and Chris
