1. Software

Changes

Several files were changed to test Joystick controls. Additionally, files were cleaned by deleting unnecessary comments, grouping variables in better ways, and simplifying import statements.

Decisions

All files were test rebuilt using Kotlin (for .kt files), but then deleted as it was decided that they weren't too necessary or worthwhile at the time being.

2. Hardware

Summary

Today we worked on getting all the pneumatics hooked up. The brackets for the 6 ballast tanks were installed, the tubing laid out, and the solenoids hooked up. The pressure sensor was also installed. We pressurized the system, put a hook at the end of the climber piston, and tested the climb. The robot climbed the wall successfully, and the arm motor was able to level the robot while it was hanging, like we had expected.

Changes

Short standoffs were moved from the top of the plates to the middle, inside the belt. First hook created.

Decisions

The ballast tanks will use the pre-drilled holes on the chassis.

Concerns

Ballast tank mounting brackets were designed to be completely contained in the chassis. It is unknown whether they will withstand wear and tear partially outside the chassis. The tanks do stick up two inches, but it doesn't look like that it actually matters much. There were some major leaks, but they were fixed on the spot. Our next step is to finish the second hook and create the mounting mechanism (arm).
