What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?
The first potential risk was putting together the pseudo-golfball. Since the Alibaba order we originally planned no longer fits our budget requirements, we have to ensure that the 3d-printed ball screws and unscrews properly. If 3D printing is not a viable option, we have identified plastic shells that we can glue together to create the ball.
The second risk is getting the BT functionality appropriately integrated with the RPI. Currently the Bluetooth was successfully paired with an iPhone app meant for Bluetooth developers, however, the Bluetooth from the IMUs will need to be paired with a raspberry pi. The raspberry pi utilizes the BlueZ open source python framework to manage Bluetooth devices. We have done some research on this and how to park it with our IMU but we will try to implement it in the upcoming week. The IMU remains the most complicated and important part of the success of our project.
Our final risk is the course itself. Early next week we hope to build the frame and actual putting green itself. He have located all of the necessary materials for this except for green felt to give the course a putting green style. The course is a necessary piece of the system so there are not contingency plans, however, the build is quite straightforward.
Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward?
Some of the current CAD designs we have for our screwable golf ball are the following:

We will try printing each of them and test how well they work while attaching the IMU and RFID chip next week.
Other than this, there have been no other outstanding changes.
Provide an updated schedule if changes have occurred.
No schedule updates at the moment.
