The linear slide bucket works with the catcher mechanism to score minerals in the center lander. Throughout the season, the design of the bucket has changed significantly, going through several designs and prototypes. (see picture below). All versions were designed using TinkerCad and made on a MakerBot 3D printer.

   The first prototype (red) had solid walls and inward sloping pyramid ramp.  The ramp was to separate the minerals to prevent blockage, however, it proved to be too large. The second prototype (orange) had a flat bottom and a notch in the front for the catcher to rest in. This bucket was somewhat successful however, the lack of ramp caused the minerals to land on top of each other and fall out of the bucket.  The third prototype (yellow) had a ramp that sloped from one side to the other. Like the first prototype, the ramp in this design was too heavy for the robot. The fourth prototype (green) had hexagonal holes in the walls to reduce weight, however, this resulted in an overly heavy floor.

   The final design of the bucket (blue) includes hexagonal holes and a ramp. It is lightweight which reduces the amount of stress on the Servo motor that controls it.
