This week, the focus of our team is to finish building the mechanical part of the system and continue the testing process. Currently, our team has completed wiring the motors and combined all attachments on the board. The motor on the screw rod works well and RPi can interface with the web application. Moreover, after we received the DRV8825 motor driver and tested it out with our NEMA 17 motor, we found that the speed of erasing also improved. After testing the latency of erasing and maximum power consumption together, we also spent some time together completing the slides for the final presentation and recording a video for it.
Individually, I have also conducted the web application usability testing with one professor and one student, and they both gave the feedback that the website is succinct and not hard to use. However, the professor mentioned that it would be great if there could be a instruction to help users get familiarized with every functionality and the nav bar can be more clear, so I will also work on that and add this to our website.
Based on our schedule, I’m mostly on schedule except that we are still recruiting more participants for our final functionality testing. We will try to reach out to more professors and students and get it done before next Wednesday. I will also polish the user interface of our website based on feedback. Moreover, if I have extra time, I will also spend some time investigating how to the web application with Canvas so instructors do not need to manually enter the student ID (which is a post-mvp goal).
