| Mechanical Work
- Trevor cut PVC with the bandsaw and dremel tool. Trevor also used the belt sander on PVC and an axle.
- He hopes to install the PVC next meeting, as this is essential to implementing the bapper.
| Electrical Work
- Mentor Julie, Laura, and Akhila worked on figuring out a realistic electrical configuration, thinking that the robot should built around this.
- Akhila then made a schematic in LabVIEW, as well as a diagram in Paint to create a visual of how everything would be wired.
- The electronics will be mounted on plastic panels.
- Laura will add the electronics to the CAD.
| Linear Slide and Shooter
- Braden was able to get parts of the linear slide cut and parts of the linear slide on the robot
- Josh developed millophobia as he had to mill all of the pieces to 2.5 inches.
- Despite his millophobia, Josh managed to finish all the pieces and is thankful to be done with the mill for the day.
- Nick and Laura worked on the autonomous program they started a few meetings ago.
- They decided, as they discussed before, to start with the robot flush to the wall, instead of an angle, so it would be more reliable. No one can expect the robot to be set up at the same angle every time. Now, it starts with the robot all the way to the right of the parking zone, moves forwards and turns to the angle we started at before.
- They ran into some big issues with the NXT freezing after seeing the IR beacons. With the use of sound blocks, they were able to locate the issue. Nick and Laura added different noises to different parts of the program, and determined it froze when the encoder values were read. They then tried a test program where all it did was read the encoder values, and it worked. They could use that value in a comparison without a freeze. However, if they wrote those values to an indicator, it instantly froze. The combination of encoders and indicators is causing the NXT to freeze, but, due to lack of time, they decided to move on.
- They had to take the code out of a sub VI so we would not need to use an indicator. Hopefully, the problem can be fixed at a later date.
- The parking zone autonomous now goes until it sees an IR sensor, and this works for all positions.
- CJ with the help of Mentor Julie created a autonomous program that would go along with Nick and Laura's program. The program in theory can now drive until it comes into contact with the IR, then stops within an approximate time period.
|Outreach Notebook Section
- Today, Brad worked on writing the outreach section of the engineering notebook. He added the Kids Fest from before kickoff, and the FLL scrimmage from yesterday that the entire team volunteered at.
- The outreach section of the notebook is incredibly important
