Gorgeous and sunny again today!

Krista was out sick again today. Brad worked with Fara and Erika to fix the Trash-Collector robot code used to sort the colored cups. He also created more sound files for the Trash-Collector to call out the names of the cups. For the Racing activity, Brad disassembled the race car and verified that the race car model in the LDD is completely accurate. He also improved the commenting for the gyro code and worked on determining which of two different methods should be used to control the robot.

Reza commented the Predator/Prey codes and filled the Teacher and Students folders with the correct codes. Chris continued documentation on the Predator/Prey robots.

Fara and Erika worked on the line-following and sorting codes for the Trash-Collector robot. They changed some of the intensity values for the line follower and determined one of their previous blockers with this code to be due to the differing amount of light in the room at different times. By moving the test track to a more evenly-lit area, they were able to achieve 100% repeatability for the line-following code. They tweaked the sorting code so the robot now places each colored cup in approximately the correct location, and returns to the search area to find another cup. The only blocker they are still experiencing is that the color sensor only recognizes the yellow cup half of the time. This might be due to the grabber, and the fact that it does not grab the cup in precisely the same place each time.

Fara and Erica focused today on the writeups for their robot. They were fixing the code that allowed the robot to follow the line, which is now blue to the black square at the end.

Reza and I(Chris) worked on commenting the code for the predator and prey bot. The intro for each of the sections are now finished, the code now needs to be removed for the students, and the activities need instruction.

Brad came in, in the morning, and worked on more documentation as well
