This week, I worked with Ashira on finalizing our Final slides and presented. I also tested with a temporary RPi after ours was damaged. In addition, I debugged the SSH connection issue with the help of a friend, allowing our team to SSH into the RPi and develop more easily. On the hardware side, I discovered that a possible reason our original RPi got fried was due to an improperly soldered ground on our voltage regulator. I resoldered the connections as needed to fix this. I also helped solder the motor driver protoboards and began incremental testing with Ashira—starting with 1, then 2, 3, and 4 motor drivers. Eventually, we got 6 of them to behave as expected.
I made updates to our GUI to improve user experience by allowing some outputs to function concurrently. I also tested the dispensing mechanism and continued integrating our system toward a fully functional vending machine.
Next week, I plan to complete more testing, paint the vending machine, fine-tune functionalities, submit the poster, record the video, finalize the paper, and prepare for the demo.
