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?
Currently, the most significant risk is the mechanical functionality and reliability of our sliding actuator system. Specifically, as we finalize our CAD design this week and last, we need to add components to mitigate the slider slipping when users physically run their fingers over the braille pins. We are also ready to mitigate issues with the motor in incorrect positions with a homing sequence. We plan on having a physical button/sensor at the end of the linear gear such that our code will be able to simply direct the motor to spin in that direction until the sensor is activate, which can then a reference “home.” Finally, there were not many changes to the system except for a decision between two different motor models that were ordered.
Here is an updated schedule for our team, given that our progress was behind the previous iteration:
