November 2nd, 6th and 9th

This is David and Alex. On the second of November, we worked on nothing but the robot. We worked on the house mission, and got it to the point where we can almost always gather all of the items. We tried to get the light sensor to work, but it was very difficult and we did not choose a very good line follower program.

That was pretty much all that we did on the second, but in between the second and the sixth, we found a new line follower program. On the sixth, we worked on the house mission again. We still couldn't get the light sensor to work so, we found yet another line follower program.

On the ninth, we tried the new program. It worked much better at the beginning, but then we decided to revise our plan and not raise the house or open the window. Now, we have decided to work on the directional arrows and the floodgate. We have a very good idea for how to set up the arrows. It's also very simple, but the only problem is that it takes up a lot of memory on the NXT. It shouldn't be that big a problem, but it could be. In any case, we'll do it and see where it gets us. While we worked on programming, Nic and Cheyne built a duplicate robot. They decided that the best way to differentiate between the robots was to make the second one as luridly colored as possible. So, all the arms are yellow, green, red, or other unconventional colors. And, they're not put on in any kind of pattern or style. So, we know which is which.

We also did a teamwork challenge, where we had to make two pillars to hold a yardstick up over a box, and then build a cradle for a pool ball to stand on top of the stick. It was difficult, but we got it all done in time.

That's all that we did for those last three meetings.
