Today we had to do our presentations on our robots we made. I was nervous all day. I got to school at 2:30pm to meet up with my partner to finalize our powerpoint. There were 8 groups; we were the 5th one. Somehow I managed to keep my cool for the most part during our presentation. On retrospect, I did forget to mention a few things, but I can't change that. It was essentially our last day of actual class. Tomorrow is just reorganizing and putting things away. Below is our Powerpoint
I've put the footage at the end of these slides.
And this here is the video footage of our robot at the competition. I would like to remind you that the robot became stuck in a loop due to a small error in the programming.

Day 16: Pre-Presentation Presentation
Apparently, there are no more classes involving new material. Today the teacher discussed, in full detail, everything there is to know about presentations. Well, actually just the presentations that we are all going to have to do tomorrow. It would be easy except that it needs to be at least 10 minutes long. To the right is the Rubric. We spent the class brainstorming and creating our powerpoint presentations.
Saturday: Robot Competition
Today we were to have our competition. I showed up at 10:30am roughly, and my partner was already there. He had added to our code the previous night and was doing more troubleshooting before the competition started. It was a continuation of Thursday and Friday, what with the sensors all being on the fritz. When the competition time came, we had to keep our fingers crossed. Unfortunately, that wasn't good enough, and our bot just went in circles. We tried to do an emergency reprogramming, and managed to do so, but it still wasn't good enough. We couldn't get the properly colored can. On the other hand though, almost all of the other teams shared our fate, save for one, which by some miracle, actually did what it was supposed to. Here's what our bot did.

Day 15 & 1/2: Troubleshooting Sonar, Line Sensor, and Color Sensor
Today was more hurry up and wait. We were getting close to perfecting our bot when we discovered that the color sensor no longer registered efficiently at all. Its range was reduced to less than an inch plus it had trouble recognizing the color red. Most of the day was spent trying to get it to work, but our efforts were wasted. The sonar was acting up as well, with the range also reduced. More interesting, my line sensor was acting up too. I checked the emitter and it seemed just as bright, yet the debugger showed that the sensor was getting poor values. We returned the next day with the intention of fixing these problems, and spent that day continuing the troubleshooting. We had to make compromises and were unsuccessful in restoring the sensors' former reliability.

Day 12: Vex Bot Sensor Adjustments
Today was pretty slow. We worked on getting the sensors rigged to the Vex Bot, and to see if they were working properly. My partner managed to finish his color sensor too, so we hooked that up as well. Today was mostly troubleshooting, and nothing very notable happened except that somehow the programming I'd made had gotten all messed up. Nothing had changed in the code, but the bot wasn't operating properly. I wasn't able to figure out why.
