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 most significant risks are the components we are able to find and afford in terms of size and power. Our main issue is the small spacing of each braille cell from each other. However, we have found at least two backup plans of actuators we can assemble ourselves in case the sliders don’t work.
• 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?
There were changes made to the block design and implementation approach as referenced above. We have shifted to a more elegant and simpler design approach which address our power and size concerns for now. The 3D printed sliders will have engravings that at different positions engage each unique combination of 3 pins per each braille column. This eliminates the need for small actuators for every single pins.
• Provide an updated schedule if changes have occurred
There have been no changes to the schedule so far, since we shifted and caught up this week. We will observe our progress this following week and adjust the schedule then, if necessary.
