This week, the SmartLockers team developed sketches for some new concepts and ideas to integrate into our existing design for the purpose of making the lockers more modular. The team met this week on February 12 to discuss these lockers’ new design; the sketches and brainstorming are shown on the image to the right.
The idea is to add hinges on the inside edges of each locker to make them easier to set up and put away. In other words, this would be a “fold-able” concept. This idea surfaced when it came to stability. One team member pointed out that by placing rod-type of design on each edge, the lockers would be placed in one space and would not be able to move once set up. Additionally, a wooden locker prototype was also shown and discussed upon among the team. Lastly, this week the team also focused on designing a poster and presentation for the IEEE expo on February 18.
After creating a draft for both items, it was then presented to Dr. Julia Thompson during the following class hours. Using Dr. Thompson’s constructive criticism and feedback, the team worked on polishing the project presentation while spending time during class to finish the project poster. This included editing text, creating new image concepts, and striving to make the poster look more appealing. After working on it later that night, the team sent the poster to Dr. Thompson to be printed. To the right is the final poster creation that will be shown and demoed at the expo.
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.
Thanksgiving has come and gone and Christmas it just around the corner. With the year coming to an end, the Smart Locker team would like to remind everyone to stay warm, hydrated, a wish everyone a happy 2019.
Below is a draft of the Front-end UI flow chart on what we expect the screen will show for the advance locker system. Our team software engineer will be using Adobe XD to create the UI. The backend will be running on a Raspberry PI with a touch screen as interface.
A mock up of what main screen can be seen below. The UI will be touch screen so anyone that has experience touch screen smartphone will have a easy time navigating the menus.
Our software and computer engineer are still working out the bugs of the system. More to come.
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.
