Currently, the most significant risk is integrating all three of our subsystems together and achieving a high accuracy for our overall system. We have already integrated two subsystems and will be integrating the third this week. Thus, we will have about a month to test our system and make appropriate changes in order to improve its accuracy. We want to also ensure smooth user interaction with our interface without interruptions.
We have decided to stick with Arduino instead of moving to the Pi in order to stay on schedule. If we had stuck with the Pi we would need to wait a week for additional circuit components to come in.
No changes were made.
