From this website (http://itp.nyu.edu/physcomp/sensors/Reoprts/QRD1114IRSensor), attempting to develop a test for the IR sensors using LEDs.

January 22nd, 2013

Worked on the planning report. (functionality part)

January 23rd, 2013

Presented our progress and submitted the planning report.

Pololu IR Transceiver Video (Not made by me)
Transmission and detection cycle more than one thousand times per second => once every 0.001s
Website: http://www.pololu.com/catalog/product/701
3 Transceiver + Shipping : $96.85 --- Not plausible/ too expensive

February 5th, 2013

Updated the blog to attempt to satisfy the requirements.
- added more pages, updated information

February 6th, 2013

Working through SolidWorks tutorial for Beacon design.
Designing Beacon to satisfy robot dimensions

February 7th, 2013

Had the design interview
Improve on blog

Standard golf balls are 1.680 inches in diameter which is around 4.2cm
Thicket must have a maximum footprint of 20cm x 20cm including all components
Have to select a motor to open/close the hole below
Have to select a sensor to detect the robot's presence
Might have to make another layer for batteries/emitter circuits
Might have to adjust height to fit the final robot design

Made a dummy beacon
Attempting to design a coordinate system for the arena

<uint8_t> array [10] [17] = {
   //as many vals as dim1 [dim0] [dim1]

  // 0 is straight
  // 1 is left turn
  // 2 is right turn
  // 4 is beacon
  // 6 is wall
  // 9 is starting point

  // 10 is not explored

Detecting Beacons through ranges of values

March 11th, 2013

Updated blog based on Wiki checklist (functionality list, expenses)
Worked on Rescue Algorithm/Ball Retrieval System
Helped with interrupts design in Arduino code
Tested Chassis with integrated circuitry on the arena
Attempting to update 2D Array Coordinate System.
