Week 8

This week, I worked with Luis on developing some pseudocode. Therefore, we tried to understand the Processing software that was used by last year's team first. We were able to download the code that they had written, but we did not have the correct XBee device that would allow us to access the graphical user interface. Therefore, Luis and I would have to wait until next week in order to fully understand last year's team's code.

 I also helped test the sensors that would be used, which included: Magnetic reed switch sensors, Ultrasonic sensors, and RFID sensors. All sensors worked perfectly fine, but it was decided to have the RFID readers placed on the podcars rather than on the track. This was decided because placing RFID readers at each station would require at least one microcontroller and one XBee device per station, which would require a lot of wiring and extra complications that are simply unneeded. Instead, the RFID tags would be placed at each station so that each station would have its very own identification code and allow us to know exactly which podcar reached which station without the extra wiring. The only downside to placing the RFID reader on the podcar is size constraint, but that is an issue that could be solved.

We are a slightly behind on our schedule, but we are starting to pick up a lot of momentum in our progress. I am confident that Luis, Chris, and I will be able to create a successful prototype by the end of this semester.
