Open House 2011-12-17-Saturday - DC FTC Qualifier - Washington, DC Matlab Logo
[Renee] On December 17, 2011, we jouneyed up to Washington D.C. The Washington D.C. qualifier was held at H.D. Woodson High School from six in the morning until about seven at night. We worked with Mrs. Denise Lewis and Mr. Bill Duncan to volunteer for this event. We spread the word to the Robobees and one of the mechanical mentors volunteered as an inspector. Our whole team volunteered for this event when we learned that they were low on volunteers. At about seven that morning, Erik and I were asked to debug some problems with 5081's robot. It wouldn't move its servos. The problem was the servo wires being plugged in backward. The teacher then asked us for help with LabView. He didn't know how to program the robot for the match. He was using the LabView tester to test the motors and the servos. We could't figure out how to do that so we asked around the teams in attendance until we learned that there was nobody that could help the team. I then asked to borrow a different team's copy of RobotC. I wrote a quick tele-op program for their robot. This allowed the team to compete. One of the other teams there, 2912, came with just a metal frame. They asked for some some help and I worked with them. By the end of the day, they had a baseframe up and running. They were able to compete in the last of their matches. The kids on this team weren't even on the FTC team. They were members on the school's FRC team. They were asked to fill in that morning or the night before. Their compiler version of RobotC was old so I borrowed 5083's compiler again and gave the same program I gave 5081. They were very happy to finally drive the robot. Earlier in the day, 5083 had asked for some programming help as well. They had some questions on autonomous and teleop programming. I went over things with them. One time when their robot wasn't driving and their Samantha wasn't working, I noticed that their Samantha power cable was unplugged. When I held it up, they stared at it and then scrambled to fix it. Both of these problems were because of wiring. The data cables were in backward. During the whole day, I was known as the lead software help. I wasn't the only person helping though. One mentor from a different team showed up and was able to help teams with some of the LabView problems. Both of us were busy the entire time. Even during some of the finals matches, we were busy helping those teams. Daddy and Allan were telling people to go and find me if they needed help. This wasn't my only job though. I aslo helped Daddy with FTA-ing. During software inspection, the music was loud enough that the teams couldn't hear Daddy over it. I was told to relay Daddy's instructions to the teams. During the final matches, the FCS didn't work well. It would drop teams and joysticks. One match it dropped all of the red joysticks and both red robots at the same time. Daddy called a re-match even before the score had been counted. He moved the teams to the other field. Even before the match started on this field, the FCS didn't work right. Daddy told the FCS operator to shut down everything and then re-boot it. This seemed to work and the matches went on as planned. On one of the matches, three of the four robot's brains locked up. They all locked up during the last part of teleop but not all at the same time. Daddy would then go check the robot as much as he could. Allan, the FCS operator, and I were all watching the robots and the FCS during those matches. During one of these matches, Mrs. Jo-Ann Halloran was talking with Mommy. They were discussing brain lockups. Mommy remembered that I had written a program that locked the brain everytime that it was run. This occured because the program was looping too fast. Mrs. Halloran was very interested and asked us for the program. We said that we would send her the program. This discussion was caused by the match three brains locked. Mommy remarked that the lockups might have been caused by the RobotC bug. She had us ask the team what compiler they were using. Two of the three teams was using RobotC. This was not a definite conclusion that RobotC was at fault. It did let Mommy have a good data point for basing other conclusions. During the final matches, Daddy needed another trained FTA to help so Allan went over. He left me in charge of scoring. He showed me how to use the software and we worked together entering scores. I was in charge of the timer for the audience's display. I was supposed to start the timer when Mr. Duncan said go and continue it at the beginning of teleop. I was then shown how to enter the scores and how to display them. This allowed me to see how well the robots were performing. After the matches were over, we entered the award winners into the software. While clean-up had occured, someone had turned off the projector. Daddy and Allan finally got it to display the award winners. It worked until the Inspire winner was announced. It wouldn't display the winner at all. We worked quickly but we never got it to work. The software's logs were then given to Mrs. Jo-Ann Halloran to take back to FIRST for their records.
