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?
One of the biggest risks as we get close to finalize the 3D printing is ways to prevent jams and smooth transition between different braille patterns. To mitigate these possibilities, we are experimenting with different sizes of braille fonts as Ziyu is testing with different dimensions of the braille caps and sliders on his 3D printer and to complement that, Samay is looking into more motors and ordered a variety of them with different stepping levels and ranges. In terms of the software, the testing has reached 100% with grade 2 braille and is ready to be implemented to the whole as soon as the hardware is finalized.
• 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?
Even though we are switching through motors, the price changes were minimal and not causing any changes to our planned budget. The schedule remains the same from last week where we had made changes to expedite software testing and 3D printing process. We are sticking to this schedule and it is our current priority to have the braille actuators and 3D design run smoothly by the start of the next week so we can put it together with the software.
