A lot of the parts came in this week, so David and I tested the parts out together. We were able to check the battery output, buck converter output, Pi camera connections, as well as motor functionalities. In terms of personal tasks, I was able to create a rudimentary card dispenser model, and also 3D print it with the rollers so we could start calibrating the amount of pressure we might need on top of the cards, as well as making sure we could dispense one card at a time. We figured out that with smaller designs, the 3D printer was struggling to get precision, meaning I should insert more tolerance into the design starting from the next design. Also, I have started preparing for the design presentation, as I will be presenting this time.
With the modified schedule, I am still on schedule. Instead of doing the lower body integration this week, I have been designing the upper body/card dispenser, scheduled to take about a week, which is what I have finished. This coming Tuesday, we will be ordering screws and some other missing parts. Once all of these arrive and have the gears 3D printed, we can start motor testing on the lower body while still prototyping with the dispenser which takes about half a day to print. I would like to get the lower body to turn by the stepper motor by the end of February according to the schedule.
