Team Blog #20

SSST Blog 4/9/2020

Progress for this week:
Due to the recent changes that the team had to undergo, most of the week was spent refining and finilizing the new project goals.

Controls Team
Because the controls team does not rely heavily on what was available in the superway center, the scope for controls did not change much. Because time was spent adjusting and adapting, some dealines had to be pushed back and a complete physical system that incorporated the app, arduino and the two pods had to be set aside. However, both the iOS app and the arduino code will still be written so that it could work in unison to control the pods. This past week a successful table top sysetm of the motors and sensors (which include the servo motors and the pixy cam) was developed and tested. With the BLE connecting, research was conducted on how to incorporate user inputs that would send specific signals to the BLE.

Guideway Team
With out access to the superway center and the maker space the guideway team had to put a halt to manufacturing. Instead the team has decided to focus on developing a detailed solidworks assembly of the guideway along with an animation and simulations. The animation of the bogie traversing along the guideway would prove that the design is reliable and that it would have worked. The simulation would provide confidence in the design by proving that the parts would not fail.

Bogie Team
Like the guideway team, the bogie team had to revert to 3D modeling and simulations. This past week the team implemented some design changes that needed to be done on the solidworks model. this consisted of changing the location of the pixy cam. The CAM was moved from the front of the pod to the bottom after it was observed that it would make it easier to obtain a clearer reading of the barcodes that would be utilized. The team also changes some parts of the model so that it could properly fit the electrical components that would be used. Renders of the pod was made in a clear material to show how all the components would of fit into the pod.

Plans for next week:
This next week the controls team will work on implementing promps with usable buttons or text input. While the app is being developed refinement on the arduino code will also take place. The guideway team will focus on developing a working y-switch mechanism and rail on solidWORKS. For teh bogie team, work will be done on rendering the final components needed for the bogie. The small scale team as a whole wants to provide an animation of the whole sysetm along with some simulations so everyone will pitch in to research on how to do that.

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. Figure 1: Barcode recognition by Pixy2 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 ...

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...
