Robot Group (Nick B, James, Thomas, Nick C)

• Next Meeting: Monday at 8pm
• Tasks
  • Design robot
  • Decide how to divide work of building robots
  • Build robots
• Completed:

                      Two bots, each travels in one dimension with the motor in PORT_A.
                      The bots have a sensor tower with four compasses at the 'Front'
                      and the motor at the 'Back'. The compass pointing towards the
                      'Front' is in PORT_1 and the rest go clockwise. So the one to the
                      'Right' is in PORT_2 and so on.

Software Group (Nick M, Sam, David, Dylan)

• Next Meeting: Tuesday 8:00 AM (Communicating via email)
• Tasks
  • Due ASAP: Magnetic Mapper code v1.0
    • Make start coordinates and Room ID passable by argument as an alternative to standard input
      • Right now they must be reinput every time the code is run
      • Compass IDs and expected headings can also be argumentized, but it is less straightforward because of a potentially variable number of compasses
    • Look at code for other potential improvements and document them in the wiki

• Old tasks (done)
  • Respond to key input (done)
    • This is not implemented ideally. Currently one press starts the robot moving and the next press stops it instead of the robot moving only while the key is held down
  • Implement motor functionality (done)
  • Collect data
    • Sensor IDs (done)
    • Timestamp (done)
    • Room ID (done)
    • Coordinates (done)
      • (x,y) by tile (done)
    • Expected Sensor Data (done)
    • Actual Sensor Data (done)
  • Using Brad's function, write data to CSV file. (done)

Testing/Automation/Refactoring Group (Aaron, Nick C, Dylan, Brad, Gil)

• Descriptions: Testing, Automation, Editing/Refactoring
• Next Meeting: Tuesday @ 6:00
• RESULTS of TESTING
  • First in magmapper.py there is a call to get_type( ) but there is no get_type( ) defined.
  • Second we need a better incorporation of calibration of compasses, so that it happens as often as necessary( however often that is).
  • Third the bot has trouble staying in a straight line with current controls, as the stopping method is very sudden and causes the bot to unbalance and wiggle.
  • Fourth moving the bot manually is faster and more precise than using the interface.
  • Fifth it would be nice to know when the data collection was done. At the moment it says "Recording data..." but doesn't tell you when its done.
• Tasks
  • Test magmapper.py
    • Due Date: Tuesday at 8am
    • Owner(s): Dylan
    • Subtasks
      • Make sure documentation is clear (DONE)
      • Write a script to ensure each line of code in magmapper.py is tested
  • Test nxt_common.py
    • Due Date: Tuesday at 8am
    • Owner(s): Aaron, Dylan
    • Subtasks
      • Make sure documentation is clear (DONE)
      • Write a script to ensure each line of code in nxt_common.py is tested
  • Test record_data_lib.py
    • Due Date: Tuesday at 8am
    • Owner(s): Dylan
    • Subtasks
      • Make sure documentation is clear (DONE)
      • Write a script to ensure each line of code in record_data_lib.py is tested
  • Compass Sensor Calibration Test (DONE)
    • Due Date: Monday at 8pm
    • Owner(s): Dylan, Gil
    • Purpose: Do compass sensors calibrate differently? NO Are some more likely to calibrate inaccurately or imprecisely? NO
  • Compass Sensor Interference Test (DONE)
    • Due Date: Monday at 8pm
    • Owner(s): Gil
    • Purpose: Do compass sensors interfere with each other when placed close together?
    • Results: Placing the sensors as closely as possible to each other, Gil found no interference.

Environment Preparation Group (Brad, Patrick)

• Next Meeting: none
• Tasks
  • Determine Room Dimensions
    • Due Date: Tuesday at 8am
    • Owner(s): Patrick
    • Results
      • D128 - 22 x 28 (EW x NS)
      • D129 - 13 x 15 (EW x NS)
      • D124 - 24 x 28 (EW x NS)
      • The origin is the big cross in the center of the room. North is marked with a diagonal arrow. North is positive on the Y axis and East is positive on the X axis.
  • Mark off origin, quadrants, and regular periodic difference
    • Digitally make note of "unreadable" tiles, i.e. ones with something immovable on them
    • Due Date: done
    • Owner(s): Patrick

Data Collection Group (Michael, Tristan, Gil)

• Next Meeting: Tuesday at 8am
• Tasks
  • Data Collection Howto

Data Synthesis Group (Brad, Patrick)
