COMPLETED:

This week, the team came together to discuss the direction we would take regarding the small scale project. Currently, our idea for the project was to make improvements on the track that had already been built, along with refining the controls and bogie to get it all to work properly. However, after discussing with Mr. Swenson about alternate ideas that he had to the project, we debated on taking a different direction by building even smaller tracks made from laser cut material.

PROBLEMS:

There are several problems with both the options that we have discussed. Originally, the small scale track as seen in Figure 1 was created from last years small scale team. This design has many imperfections, but we already know all of them. Of course, with all those defects there must be some type of solution, but the problem with that in itself is figuring out which part to focus on first: bogie, controls, or track?

Figure 2. Alternative track

Figure 2 represents the alternate idea that we had pitched to us by Mr. Swenson. By discarding the problems from the track and sticking with an alternative design for the small scale guideway, we could focus more on the bogies and controls. There has already been designs and progress for this small scale track, but the only downside is that it would be hard to realistically scale up in the future.

We approached Professor Furman about both topics, and he gave us significant advice on how we should decide on what steps to take next. 

NEXT STEPS:

we will be holding a meeting over the weekend to further discuss the final approach we will take for the Small Scale Project. Once we have decided what path to take, we will then create a Gantt Chart and presentation, begin designing ideas using CAD and other software, as well as creating a bill of materials for future reference.

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 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 ...

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...
