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?
We are working on integration, and the two main issues right now are fitting all the needed components into the bottle’s bottom chamber and detecting density and uprightness. For fitting all components, we are shortening wires as much as possible, and looking into fabricating a larger chamber.
For density and uprightness, we noticed that we couldn’t attach our pressure sensor directly to the bottom of our bottle, since it is slightly indented and the sensors are somewhat fragile when bent. Thus, we plan on fabricating an adapter (as was suggested to us in the weekly meeting) to improve that. We may need more pressure plates to work on this.
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?
We will need to purchase more pressure plates, but that is well within the budget; similarly, we plan on fabricating the adapter for the sensor and a larger bottom compartment, but we have access to printers we can use at no cost.
Here’s the bottle, with mounted sensors, that we assembled this week and will use for our interim demo:
