Progress for this week:
Controls
This week the controls team continued learning about hoe to integrate the BLE into the the project. This consisted of watching many videos and reading several indepth tutorials. It should not take much longer to be abel to successfully integrate the BLE into the iOS app. Another task which the team has been working on is testing the new stepper motor that arrived. From the testing that was done, it was concluded that modifications may have to be made to either the code or the circuit to properly use the driver board.

Guideway Team
The Small Scale Guideway Group focused on modifying parts of the track to fit the required dimensions. The overall size of the track will be 96 inches long and 48 inches wide. Straight parts of thr track will be in increments of 16 inches while the curved parts will be modified to adjust for the inner and outter curvature of the track. Overall, the model will consist of pieces that will fit onto one another using a layered cake design. Each piece will be overlapping one another and then snapped together using a connection that can be easily removed.

The CAD models for each piece of the track are currently being constructed, with hopes that we will be able to waterjet the pieces using 0.5 inch thick plywood from the Superway building at the Makerspace. If the plywood does not stay consistent, we may look further into buying a higher quality grade of plywood, such as multi-plywood, or using other techniques such as laser jet cutting.

Plans for next week:
Over the weekend the team will get together to make further progress on the project and to organize the next team presentation for the class. By next week the small scale team should have successfully implemented the BLE into swift and the guideway team will be starting on fabrication.

SSST Blog 10/17/19 Progress for the week: Controls Team  This week for the controls team, Asmaa continued working on combining the two main Arduino codes which we have so far. One of the codes was the one which implemented the ultrasonic sensor to get the motor to slow down if the ultrasonic sensor detected an object too close to it. This mimics what we want the bogies and pods to do once they are fully operational, it is essentially collision prevention system to where if a pod gets too close to another pod, the ultrasonic sensors will detect the proximity, and get the motor to slow down. The other Arduino code which we have is for the BLE. Using a pre mad app to test if the BLE works, Asmaa wrote a code to enable the Arduino to turn an LED on and off depending on the input of the user on the app. If we typed 1, the LED would turn on and if we typed 0, the LED would turn off. Asmaa combined both of these codes into one, with the slight difference that once we have our own iOS ap

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 sent

SSST Blog 3/4/20 Progress for the week: Controls Team: The controls team this week made significant progress with the pixy cam. The cam is now integrated into the main arduino code with the BLE, ultrasonic, and motor. The program waits for an input from the BLE then looks for the corresponding bar code, as shown in Figure 1., using the pixy while running the motor. It stops when the bar code is found.  Figure 1:  Bar codes that the Pixy cam will recognize as different stations.  The blog man who wrote the guide to connect the iOS app to the BLE also responded back to Julio, giving useful tips to try to fix the connection issues. These tips will be used in the upcoming week to help run the app smoothly.  Guideway Team: The outer loop of the track was assembled onto the base. Most if not all of the nuts, washers and rods were used, as well as the straight and curved pieces. More of these pieces and parts will need to be bought or manufactured in the Makerspace. The same
