Blinky

October 18, 2011 (3 hours):
Attended scheduled meeting to decide on project parameters.
Vehicle Platform: Airsoft RC Electric Panzer Giant BattleTank

• This vehicle was chosen because of its size and peripherals. It has plenty of room with a size of 2.5ft x 1ft.
• It also has a moving turret already which is perfect for mounting a camera. In addition, the tank fires air soft pellets! This control can be investigated and added to the specs for the control of our vehicle if we want it to be able to fire.
• We were concerned with the speed of the R/C cars of equivalent size - a lot of them up to 60mph. In addition, their cost was ~$150 and we are anticipating having to buy 2 to compensate for tearing one apart. At such a high speed, sensors to increase the autonomy of the vehicle would be virtually useless.

Wireless Module: RN-XV module

• This module was simply chosen because of price and because it communicates through UART which is available for the Cortex-M3

IP Camera:TRENDnet TV-IP110WN Wireless N Internet Camera

• It was very hard to find an appropriate IP camera. We wanted to find a camera that didn't depend on software. This camera is on the lower end of prices (hundreds were looked at) and it should work great.
• All IP cameras have to be assigned a static IP address. This will need to be an option on the controlling website. Even if the camera was integrated, an IP update on the vehicle would still have to occur.
  

IR sensors and pushbuttons were chosen based on price. There is no need for long rang IR sensors.

October 19, 2011 (2 hours):
I did more research on IP cameras as I felt very unsure of using one. Not only did I feel like using one would be lame, there were just too many problems to deal with. One major problem is that IP cameras require that you connect to them via Ethernet and set up a static IP address for them. This would be extremely inconvenient for our purposes as every change in location would require a manual change in the camera's IP address. Also, most IP cameras require that you use the manufacturers software to access them - usually with a login and password on a browser. With time I'm sure our group could hack this requirement, but that is not really something we would like to do. (Not to mention IP cameras run ~$90 for the cheaper models)
I found a $10 CMOS camera on SparkFun, and one of the comments stated that someone had success interfacing to it with a Cortex M3! This will cause a change in our wireless transceiver as the one we chose previously would not be able to handle the throughput needed. We will be able to use the same line of transceivers, we will just have to pay more. There are many other CMOS cameras that we can choose from and this will give us greater flexibility in terms of implementation. It will be much harder to deal with the video feed ourselves, but will surely be more rewarding in the end.
Also attended VIP poster session which went really well.

October 20, 2011 (1 hour):
Found a new wireless transceiver that can potentially handle the data rate for the video feed and has i2c and well as other interfaces. More details on this later as I dig into the datasheet. Also created groups that we will break up into for project development and updated all of my research on this page: Research
