Yes, we are a bit behind. Our new "Trac" system says that we are about one week behind. Not good. This morning, we met at Lynbrook to get as much work done as possible. The software guys reflashed our 2011 robot, the hardware guys tried to make a finalized version of our drivetrain, and the events guys finished up planning our trip to New York.
While all this was going on in room 612, Mr. Xie and Mr. G were giving lectures about software design. Mr. Xie went over drive train control. He talked about the differences between PID (proportional-integral-derivative) and Lead Lag control designs. Mr. G explained our current CAN Bus (Controller Area Network) system, and how information flows from the cRio to the 2-CAN, and then to the individual robot motors and parts. He also talked about our Jaguar speed controllers. Next, Mr. G went over some of the important points for newcoming programmers. This includes destroying previous commands, looking at previous years' code, and learning from experienced programmers.
We didn't finish all of the item on the agenda, because we ended up drifting to room 612 to get more work done. After a short lunch break, many of us returned to continue working. At the end of the day, the drivetrain was looking better and better. Only a few more tweaks left!
