Doubt it. And not enough connectors to make a complex PVC "ball" to grab either, unless wood is involved.
I'm going to assume the PVC is EITHER for yet another goal with fingers pointed up, or else up to 12 "rungs" on a ladder with wooden sides. Holes in the wood and the caps nicely act as retainers for a ladder. You also have enough plywood again for a 4x4' by two layer base again, to form a static version of last year's rolling goal.
Note that the only significant steel in the BOM is the four washers (item 14).
Their 2" diameter would nicely work with the magnet.
One possibility is that the washers are mounted in various positions on the static item, and that the magnet is attached to the box, making a grabbing "token" that can have up to four separate positions.
Another interesting thing to note is that you can EXACTLY cover two sides of the plastic box with the four washers (two per side), to make a box that can be easily PLACED onto the magnet by the robot.
I HIGHLY doubt that the magnet goes on the robot. A good use for it would be to have either Hall Effect sensors or Reed Switch in the kit, and DETECT the magnet with the robot.
But, I'm pretty sure that the washers and the magnet do go together.
Hey... You could make a "magnetically selectable" device of some kind with four detent positions! Imagine a "selector switch" for three alliances and Zero, that robots would have to "set" to determine who would own the points in the goal. (Probably not that much fun though... You'd be fighting over the "switch", or hovering over it.)
Since there is no chain included, the ANSI 35 link is probably a "poor man's coupler/hinge", to add a degree of freedom to something small on the assembly.
BTW... Does anyone here think that the quantities of the 4-40 and 10-24 nuts are misprinted?? There are (5) 4-40 screws and (2) 10-24 screws, but the OPPOSITE quantities of nuts for them.
