We demo'd our first sub-compartment to Prof. Kennings last week. We worked tirelessly the week before to 3D print the joints necessary, buy and machine the panels needed, set up a very basic version of the app, and get the communication between the mobile app and Raspberry Pi working. After some successful 3D printing we found that the joints fit the panels nice and snug with no "wiggling". Without further adieu, here's a demo of the said sub-compartment:
Last week, the mechanical team was waiting on the big PCB (V2) to confirm the fit of the front joint. In the meantime, we made some changes to the front joint to make the connectors more accessible for easier attachment, removal, and diagnosis. We have also been continuing to 3D print the back joints as the design for this part has been finalized and we will need 27 of them in total. The software team has been working hard to get the basic functionality of the item identification working on the app.
Upon receiving the new big PCB (V2), Deji found some connectivity issues and worked with employees at the 3D print center to diagnose the problem and re-make the big PCB (V3).
Next up on our mech and electrical to-do list is printing the small PCB and checking connectivity between the connection panel and the smart joint, once we have a working prototype of the big PCB. In the meantime, Helen will be hitching a tent in the WATiMake clinic in order to print the back joints we need, while keeping an inventory of the 3D printed parts we have and the ones we need. On the software to-do list is the basic initialization functionality of the app as most other functionalities will be variations of this.
