Team Status Report for Apr 20, 2024

What are the most significant risks that could jeopardize the success of theproject? How are these risks being managed? What contingency plans are ready?

The most significant risks right now include the jamming issue on the braille pad. Due to the flimsiness of the braille pins, there are cases where the braille pins are stuck while the slider slides to the correct position. To manage such failure, we are working on a reliable jamming solution where we used the builtin jam detection on the motor to actuate the slider back and forth around the target location in order to reach the target. We also faced various communication issues with wifi communication between the webapp and the arduino. To resolve this issue we are going back to our serial communication system that is more reliable and able to transfer data faster.

Were any changes made to the existing design of the system (requirements,block diagram, system spec, etc)? Why was this change necessary, what costsdoes the change incur, and how will these costs be mitigated going forward?

We decided to change the data input method on the web app from importing a txt file to manually typing the word on the web app. We decided to do so because a peer commented that txt file import reduces flexibility and requires the user to be well-knowledged in creating a txt file. This does not change the cost in anyway.

Provide an updated schedule if changes have occurred. 

No schedule changes since our last demo.
