Intake.java BallManager.java

Before brainstorming and designing possible intakes, a few goals were established:

1. Consistency: all balls ingressed (regardless of ball position, wear, or inflation) should take a similar path and end up in the same place.
2. Vector balls towards the center of the robot for easy indexing (if possible without sacrificing item 1 or item 6)
3. Simplicity and easy in-house machinability
4. Packages well with existing mechanisms, particularly the tower
5. Either be floppy or rigid enough to handle strong impacts and retain function
6. Intake balls at a rapid drivebase speed

Initially, many concepts were brainstormed, but majority fell into one of two categories:

1. An “over-the-bumper intake (OTB)” in which cargo passes over the bumper into frame perimeter
2. A “cutout intake” in which there is a cutout in the bumpers for cargo to pass through

Based on our design constraints (especially items 1 and 6), we concluded that a decision between these two concepts could not be made without testing in accurate conditions. Thus, we decided to design and develop prototypes for both of these concepts in parallel and compare results.
