Prototypes Prototypes Prototypes
After finishing our prototype session for the water gun and deciding on an aiming system,
we are looking forward to the skeeball shooter. Since we do not yet know the exact dimensions
for the skeeball shooter, we want to be a module as possible for the design. We are splitting
Task Force into 3 teams, one will work on a flywheel (Audrey, Isa), one will work on an extending
arm (Jessica, Richard), and the final will be working on a crossbow design (Erin, Via).
Flywheel: The flywheel will be a wheel attached to the motor, close to a solid wall. As a ball
is fed through, it will be shot ahead by the wheels. We like this idea because there are lots of
examples of it from FTC, and it's pretty easy to build.
Crossbow: The crossbow design uses a spring to shoot the ball. The ball will be loaded in, and the
spring slowly cranked backwards until it's ready to shoot. This idea looks good because it should
be very consistent with every throw, and we have a lot of modularity with a single design by changing
the size of the barrel, and the spring.
Extending Arm: The extending arm would be paired with one of the other two designs. It will extend
beyond the initial measurements of the boat to accurately deliver the balls.
All of these designs need to be compatible with the hull, in terms of power consumed as well as size.
We need to finish up these prototypes as soon as possible. A finished product will be given to the Navigation
team so they can begin to plan for and program the aiming system. This week we plan to have a CAD model for
each of the designs, and order any required materials.
