Progress for this week:

Controls Team:
To become more familiar with the Pixy Cam several tests were conducted throuhgout the week. After the team decided to switch over to barcodes for the stations the team saw that this method was better. A sheet of the 10 barcodes was then printed out and the team tested how accurate the pixy cam was at ientifying the different codes. The team will is now working on trying to develop a test which will incorporate the arduino along with the other electrical componenets.

Guideway Team:
The guideway team made progress on determining how the track will be supported and what materials we will use to build it. The team setteled on using mdf wood with a thickness of .25". The laser cutter cuts the wood accurately and precisely at the maker space, however, the space is only available during the week days from 10am to 6pm. The supporting stands will use 3ft long zinc threaded rods with nots and washers to clamp down onto the base of the track. All the material can be bought at home depot.


Bogie Team:
Four more parts of the pod were printed and assembled. Upon the assembly of the pod it was sound that some alerations to teh snapfit designs would have to be made. Although the team managed to assemble the pod, some parts of the snap fits fell off, and dissasembly was found to be difficult. To fix this the team will have to make some minor adjustments to the pod. The team has also continued to  work on a gearbox design that fits the bogie platform.

Plans for Next Week: 


For controls, more progress has to be made toward the BLE connection with the app. Also, the pixy cam should be integrated into the master Arduino code to recognize all station barcodes. Prior to integrating the pixy cam into the code, some barcode tests will be done in different lighting to address some concerns. The bogie team will make minor adjustments to the pod and print a second pod with the corrections. For Bogie, good progress should be made toward designing the gears and the snapfits on the bogie will also be adjusted. By next week, parts of the pod with the corrections should be printed. For the Guideway, manufacturing should proceed where the team previously left off. More progress should be made toward a completed CAD model of the track.

Team Blog #25

SSST Blog 5/13/20 Progress for the week: Since this is essentially the last blog for the 2019/2020 academic year, and the last major thing that was accomplished this week was submitting the report, there is not that much individual subteam work that was completed. Rather, everyone came together to work on the final report throughout the entirety of the last week. The remainder of this blog will be dedicated to showcasing the final results through images of each of the subteams and also of the Small-Scale as a whole. Controls Team  The final design of the controls team was two separate iOS apps, one allowing to connect and to send data to BLEs to activate the master Arduino code and another solely for a pleasant and informative UI experience. Although ultimately a keyboard was not able to be implemented successfully into the BLE testing app, a slider was added so that depending on its position, different 8-bit unsigned integer values (within a range specified in Xcode) can be ...

SSST Blog 3/26/2020 Progress for this week: The Small Scale team met this week to discuss our plan moving forward with our project after the recent changes that are going on. The team decided to continue meeting online via Zoom or Google Hangout to discuss our progress. The meetings will be happening every week. This week we also met as a class with Dr. Furman. We explained our plan with him and explained our schedule that is shown below in figure 1. The schedule shows the main goals of our team for the rest of the semester. Plans for next week Next week is spring break, but the team is still planning to meet to encourage ourselves to meet the deadlines that we set. For controls, the Arduino code will implement the switching mechanism servos. By adding this, the Arduino code will be complete and ready to be used along with the iOS app. The next step for the iOS app is adding a text box that allows the user to type data that can be sent to the BLE. More thing is planned to...
