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 be added to the app to allow for a good user interface that will be added later in future weeks. For the guideway team, the main task next week is to finish the Y-switch. A SolidWorks model is in the works that will show the new switching mechanism. For the bogie team, the bogie platform is complete as well as the swiveling connections to the pod. The focus next week is to finish the Solidworks model of the switch and its connection to the servo as well as the mountings of the servo on the bogie. The team as a whole will also look into learning how to simulate the bogie with the track together.

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 10/17/19 Progress for the week: Controls Team  This weeks progress was similar to last weeks. The controls team focused on two separate tasks. Lissette and Asmaa continued to develop the test code for the motor and ultrasonic sensors. The purpose of this code is to simulate what would happen if two bogies get too close to one another, in which case the ultrasonic sensors would detect this and slow down the motor of the bogie that is getting too close to the other bogie. There were some issues with the code last week, so this week kinks were continued to be worked out. A snippet of the Arduino code can be seen below in figure 1: Figure 1: Snippet of code to control motor speed using ultrasonic sensor  The space where the small scale team works was also searched for useful components. While Lissette and Asmaa were working on this, I (Julio) was working on the iOS app. So far I am just learning the basics of the programming language Swift by watching courses on YouTub
