2. Current Tasks Work on Microcontroller Code Receive Parts
Get in machine shop with Mechanical Drawings

3. Data Transmission Protocol
All message packets will be 6 bytes in length
Message packets include:
ON: Indicating sensor is activated
OFF: Indicated sensor is not activated
ACK: Simple acknowledgment with multiple uses
Checking to see if a message was received
Checking if a message has finished processing
Checking if still alive
I: Requesting state of sensor
M: Indication that arm is moving
R(-)XX.X: Indication to rotate XX.X degrees

4. Data Transmission Protocol (cont.)
When a cell is about to be tested, ‘R(-)XX.X’ will be sent to the turntable to tell it to rotate to a specified angle. When it has finished rotating, it will reply with an ‘ACK’ packet.
‘I’ will be sent to turntable to ensure that sensor is deactivated before testing
‘M’ will then be sent to turntable to indicate that it should start monitoring the sensor. If the sensor is activated within 3 seconds of receiving an ‘M’, the turntable will reply with an “ON” message. If not, reply will be “OFF”.

5. Tasks Completed Last Week
All GUI code implemented:
Allows for manual control of arm and turntable
Allows for all possible motions of one cell to be tested
Allows for full testing grid to be tested
User can export results as text file or as spreadsheet
User can export detailed results as text file, including results of specific arm motions within a single cell

6. Tentative Schedule
