Team Blog #20

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.

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 iO...

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 ...

Blog 2/6/2020 Progress for this week: Controls Team: The iPhone application code is being developed to work with a Bluetooth module. During this process other BLE modules are being considered as well. A bench model that includes all of the electronic components is also in the works. Once this is completed, the electronics will be integrated into the bogie for further testing.  Guideway Team: The original plan was to waterjet the unused plywood in the Superway Design Center; however, plans have slightly changed. We will be using a laser cutter instead of waterjet to manufacture components of the guideway. The laser cutter in the Makerspace is more accessible and does not require supervision during use. On the other hand, the waterjet requires supervision by staff members when they are available. To speed manufacturing, laser cutter as shown in Figure 1 was determined to be most efficient. Figure 1. Laser cutter in Makerspace. Figure 2. Plywood from Design Center cut b...
