After much work, the parts have been assembled and the SmartLocker is complete. There are a few QA points that need to be looked over and additional testing to be done. Once all those are complete, the team is planning to schedule a time to deploy the system to the Gilroy Compassion Center.
Each locker has a power outlets and USB charger. All the units are set on top of a wood platform.
The units are riveted together
The lockers will run through a tip over test to see how much force is need to tip over the system as well as a heat test. The plan is to also brace the locker to the wall to avoid the system from falling over in an earthquake.
The SmartLockers team discussed ideas for the concept folding locker. The goal of the locker is to have a set of folding locker to accommodate for pop-up camps and field events. The design will allow for quick deployment and take-down. The idea was a brain child of our community partner Ehb Teng from AtHack, inc. A few CAD drawing were made to further develop the design.
Regarding the main design. There are a few tasks that need to be completed. The first task is to test the prototype’s heat dissipation, tilt safety and current draw to ensure design verification of the locker. The team is scheduled to test the prototype next week before meeting with GCC to validate the design. The second task is to get feedback from the Gilroy Compassion Center to validate and verify the functionality and design of the prototype locker. A meeting has been scheduled to meet with the GCC. The third task is to integrate the user interface software with the locker and test its usability. Once these tasks are approved and verified, our last task would be to send the design to a outside machine shop to build a set with the specified materials and dimensions. A Prototype was made using a thinner gauge sheet metal to get an idea of the dimensions.
Additionally, the team presented at the IEEE Expo in February. The expo was in partnership with San Jose State University and Santa Clara University to show of community projects from both schools. A handful of participants received grants funding to expand the scope of the projects. The project that received funding for SJSU EPICS include, Team Aquaponics, Underwater ROV team, and the SmartLocker Team.
Winter break is over and Spring semester 2019 is starting up. For spring, the Smart Locker team will be working on the prototype and refining any problems that arise. The local chapter of the IEEE will be hosting an event at San José State University on February 18. The Smart Locker team will be attending and will be getting feedback from the community and partners.
During winter break, the design was revised to accommodate for manufacturing. The unit will have three major unique parts. A door, side panels, and top-bottom panel. This minimize the number of different parts while still be able to manufacture. The team is currently working on camus shops as well as local sheet metal shops to develop the process to bend sheet metal effectively.
Thanksgiving has passed and Christmas is around the corner. Fall semester is winding down for winter break and the Holidays.
Because the EPICS senior project course is partially an elective course, some of the members of the team may not be returning for next semester. We would like to bid farewell and good luck to Sabrina Miller, Irina Tabor, and Prabhpreet Singh. Their input into was vital to the progress of the project.
Here are the current drawings and dimensions of the smart locker system. Each unit is 13 by 13 by 17 inches. These dimension were chosen to allow a 15-inch notebook computer to fit.
After a number of group meetings and the valuable feedback from the design review, the group is working on clearly addressing the modularity of the lockers. It was found after a Monday team meeting and a Wednesday class breakout session, that the idea of modularity was not consistent between team members. The issue was addressed in a discussion and the mechanical team is now drafting methods of attaching the three types of locker door units: the large one door unit fit to hold two full backpacks, the two-door standard locker size, and the slimmer electronics charging lockers. Additional feedback from returning design review guests and former EPICS students helped guide the goal for this task. At least ten different attachment ideas are to be created and examined this week as well as the decision of whether or not the module aspect of this locker project would overcomplicate and set back the deliverables. Already, nine sketches for a module design were sketched during the lecture’s breakaway. The full list of module ideas as well as the team’s thoughts on their applicability will be posted after the group’s next team meeting.
