- 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 lifting mechanism for the door is an open feedback loop. Careful testing is required.
-We are concerned about not having enough time to do testing on the full system.
- 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?
The servo is changed to a DC motor because neither the servo nor stepper motor would cooperate. The DC motor will share the 12V power supply with the solenoid. The motor was given to us for free because it was a spare part for a Build18 team.
