Seen here are a close-up view of the rotat-
ing floor component with the motor that drives it,
and a view looking through the side of the bin at
the floor rollers.
This angled view of the robot provides a
glimpse of the floor rollers positioned at the
bottom right of the bin.
A team member fits a foam ball against the
conveyor system which feeds balls out of the bin
to be scored in a goal.

On to Scoring
When it came time to deposit the balls
into a goal, a conveyor belt guided
them to another roller that transported
the balls. If this roller rotated in one
direction, the balls would be shot out
from low on the robot into the lower
playing field goals at a rate of five balls
per second. When the roller direction
was reversed, the balls were sent up
the rear conveyor system to a turret-
mounted camera-guided shooting
mechanism. The shooting mechanism
could fire the balls into the high goal at
a rate of three balls per second.
A conveyor belt guides the balls from the bin
to a roller system that would further transport
the balls.
An outlet at the back of the robot
permitted balls to be scored in the lower goals,
depending on the direction of the roller spin.
Once the balls pass through the conveyor
belt, a system of rollers and cords send them
either out the bottom of the robot or up to the
shooting mechanism.

No-stick Bin Design
The bin was not only physically but also
metaphorically the central part of the
robot. Its ability to store a large quantity
of balls was key to the success of the
ball collection and delivery systems.
The innovative method for stirring the
balls to prevent sticking and jamming
allowed the other mechanisms on the
robot to perform smoothly.
Although only a small team, the stu-
dents on Team 86 have consistently
produced the most creative ideas. They
followed through on their creative
solutions and designed, fabricated,
assembled, programmed, and tested
inventive mechanisms.
Team 86’s solution to the ball-storage
problem resulted from a student’s
imagination. By designing a way to
overcome a problem faced by many
teams, Team Resistance lived up to its
name and team motto: “Going against
the current.” All in all, admirable results
were produced a small, home-based
workshop.
Despite its seemingly complex design, Team
86’s robot utilizes a unique and effective way to
transfer balls.
