- The Seniors:
This year, we have six FIRST robotics members graduating. Their experiences
here vary, and this page will provide you with some insight on the knowledge
they obtained from this program and a little more about them.
The robotics team operates as an after-school program designed to allow
students to develop and improve upon basic workplace and STEM (Science,
Technology, Engineering and Mathematics) skills. It is offered as a class,
with students eligible for credit upon successful completion of the course.
Students compete in the FIRST Robotics Competition, an international program
that challenges students to design and build a robot according to
requirements set down by FIRST. These requirements change annually, as a new
challenge is chosen each year. The competition is held as a means of
inspiring greater interest in the STEM fields, the primary goal of FIRST.
- This year's challenge is called "Rebound Rumble."
Robots must pick up balls and throw them into hoops mounted to the wall at
three different levels. Different point values are awarded, based on which
hoop the ball is thrown into. Additional points can be awarded if the team
balances on the center bridge with another robot for the end game. The video
below is provided by FIRST and offers a more in-depth explanation of the
The Robot Construction WEEK ONE
- Build Season: Week One (Jan. 7-13, 2012)
The 2012 FRC build season officially began on Saturday, January 7th. Our
team attended the Kickoff Presentation at McKinley High School, along with
other teams from across Oahu. The Kickoff Presentation is an annual event in
which the game for each year is announced. Teams from across the world tune
in and wait for FIRST to release the explanatory animation. The event began
at 5:30 a.m. Hawaii time, so we met bright and early that day.
At the Kickoff presentation, the animation for this year's game, "Rebound
Rumble," was played. "Rebound Rumble" involves robots shooting balls into
three different levels of hoops in order to score points. In addition, we
also received our kit of parts, courtesy of FIRST. The kit includes various
devices and components crucial to the construction of our robots. While not
strictly limited to the parts provided, we typically use them as a solid
foundation upon which to build other components.
As soon as we returned to the school, our team got to work organizing the
Kit Of Parts and took inventory.
We broke up into five smaller groups, a mix of all the different subgroups,
and created designs for the robot this year. As the week progressed, the
collection of brainstorms was narrowed down to a handful of designs. Each
group designed their own robot and presnted their design to everyone.
After presenting our designs, we split up into our subgroups and are working
on the final design for our robot. Our mentors come everyday to assist us in
designing a versatile robot that will be able to accomplish all our goals.
The Robot Construction WEEK TWO
- Build Season: Week 2 (Jan. 14-20, 2012)
Week 2 of the build season began with the continuation of designing the
robot that we plan on using for "Rebound Rumble". Our subteams have been
dedicating all their time to testing and coming up with different ideas for
each part of the robot.
The electrical team has made progress as far as installing updates,
researching and testing code. The cRIO's have been reimaged so they are
ready to run with this year's software. The retrieval and shooting
mechanisms are being tested as well. The Axis camera has been researched and
will be tested soon. The new controllers have also been tried. Lastly, our
team will finish the design we plan on showing to the rest of the team
during CDR (critical design review) presentation.
The System Integrations Team has been helping both the Mechanical and
Electrical Team. We have been familiarizing ourselves with the KOP in
AutoCAD as well as drawing up our prototypes in Inventor. We have been
learning how to make and assemble parts in 3D. This will help us find any
problems before building to make sure we are effectively using our time and
resources. Also by being able to move certain parts we are able to see if it
works the way we planned it to. As for helping the Mechanical and
Electrical, we assist them with anything they need like building prototypes,
The mechanical team has been creating various prototypes this week. The
shooter, retrieval system, and different suspensions are some of the things
that we have created so far. We learned about key physics concepts that we
could apply to our designs. We were able to test different torque outputs
and pushing forces for different wheel sizes.
The Business and Public Relations team has been working on the Chairman's
award essay, our team's buisness plan, and updating this year's website. We
have redesigned the button and t-shirt to match this year's game "Rebound
The Robot Construction WEEK THREE
- Build Season: Week
3 (Jan. 21-27, 2012)
For week 3, the System Integration Team has continued to help both
the Mechanical and Electrical Team. For the Electrical Team, we
practiced making drawing for the layout of all the electrical
components. In addition, for the Mechanical Team we drew 2D and 3D
drawings of the Retrieval, Shooter, as well as the Drive Train,
including our Gearbox. Since some components are not completely
finalized, we drew the basics of what they are designing so when
they tell us all the specifics we can just plug in the dimensions.
We used the drawings to make sure all the components fit together
nicely so assembly will be easier. Also, we continued to help all
the teams with any research, designing, prototyping, or anything
else they need.
This week, we continued to test the prototypes that we made to improve its
performance. While building the prototype, we noticed that the shafts that
we had were not the proper size, so we had to spin it down on the lathe. On
Wednesday, we presented our CDR design. We started adjusting our designs
according to the feedback we were given. We also did some calculations to
figure out what motors are appopriate for some of our designs. Knowing this
information will help us to fix the prototype and begin working toward the
final design during week four.
This week, we presented our CDR (Critical Design Review). Each subteam
presented their proposed design for our robot. After each presenation, the
mentors and students are given the opportunity to ask question and give
feedback that will help improve the design that they proposed.

Week three has passed and we are getting closer and closer towards
completing our robot. We have presented our Critical Design Review and
proposed our final designs and listed our goals for the rest of our season
to our teammates. Research has been conducted to better our understanding of
light for our camera tracking code. A turret has been designed and it is in
the process of being built. A code for our camera has also been tested and
we can take pictures for particle analysis. We have also made an effort to
organize our sensors and wires to increase efficiency and save time finding
things. To end week three, we have written out an agenda for week four.
This week, The Business and PR team has been working on designing
promotional items, such as the button we plan on giving out at competition.
We have also researched other promotional items, such as pens and business
cards. We finished the first draft of our buisness plan, and have started
trying to finish required items for other awards, like the Chairman's Award.
We continued to work on the website so that the player bios, and weekley
updates can be veiwed.
The Robot Construction WEEK FOUR
- Build Season: Week Four (Jan. 28- Feb. 3, 2012)
The Electrical team has accomplished most of the important goals that
concern us at this time during the build season. First of all we have
successfully finished our code for the drive station, now allowing us full
control of the robot’s movement. Next, our general turret design is also
complete. The turret’s main purpose allows our shooter to turn 180 degrees
right and left, making the mechanism more efficient in the competition. In
addition to the turret design and drive code, we’ve developed an equation
for pixel height vs. distance. Our equation estimates the distance from the
backboard based on the pixel height.
This week, the System Integration team has drawn 3D models in Autodesk
Inventor. So far, we have drawn the gearbox plate for the Drive Train and
Shooter. We are currently working on the overall 3D model for the frame,
retrieval, shooter, and the mechanism that will push the bridge down for the
end game.This week we have continued to assit the Electircal and Mechanical
teams, which we plan to do untill the end of the build season. We have also
been assisting the Business team by to organize the budget for the items
that we need to purchase. This week our advisor gave us a brief lesson on
writing a purchase order (PO).
This week, the Mechanical team finalized the design for the shooting and
retrieval system.The last design we have to finalize is the suspension
system. We finished gathering the parts list for the different components of
the robot. Part of our team has started to draw the sytems in CAD. So far we
have been working on the shooter, drive train, and retrieval components and
are almost done drawing them out.
This week, the Business and Public Relations team started to interview
members of our team for the Chairman's Award essay. We interviewed more than
half of the team, and plan on finishing up the rest of the interviews by
next week Tuesday. This week, we had a small problem with the links for the
website, however, we were able to fix all the links and get the website up
and running again. The website was updated with the new "Greek" theme and
given a new banner. We are currently revising the business plan that we have
been writing the past few weeks by adding more details and by being more
specific. We hope to finalize it by the ending of next week.
The Robot Construction WEEK FIVE
- Build Season: Week Five (Feb. 4-10 2012)
This week, the Electrical team finished programming the camera code. It is
now able to measure distance, we found the region of interest and increased
the camera accuracy. We created a wire color coding format for the final
wiring of the robot. This week, we also began to integrate all of the
different programs that were previously tested individually.
This week, the System Integration team has continued to assist the
mechanical and electrical subteams. We have a little time left and we want
everything to be finished as soon as possible. We started to draw out the
bridge device prototype that the mechanical team designed. We also drew the
shooter and retrieval systems. Those designs are almost done, we just have
to apply the finishing touches. Week six is coming and we are going to work
extrmely hard to finish drawing all the systems and assite the other
This week, the Mechanical team redesigned some of the aspects of the robot.
We had to draw out our new designs in CAD for the belt tensioner and the
retrieval systems. We worked on the bridge lowering device. We started to
build it, so that we can test it during week six. We got all of our supplies
this week, allowing us to start to put the whole robot together. We machined
parts so that could get them to the appropriate size. We plan on having
everything finished early into week six so there is time to test everything
This week, the Business and Public Relations team sent out our business plan
to be edited by various fauclty members from our school, and members of our
FIRST team. We read over all their comments and concerns, and fixed the
business plan accordingly. We finished the first draft of the chairman's
questions and essay. We had them revised and we are currently fixing them so
that it will be ready to submit. This week, we also designed more
promotional items to pass out during competition. Lastly, we continued to
update the website, getting ready to submit it next week.
This week two of our mentors, Ryan Fukuda and Malcolm Chun taught some of
our members to weld and machine. We were given the opportunity to observe
the welding technique called tungsten inert gas (TIG) welding. The type of
metal that we were welding was aluminum. Mr. Chun, is a certified aircraft
welder. He taught us how to machine parts. The process seems long, but it
was worth it becasue we machined beautiful parts.
The Robot Construction WEEK SIX
- Build Season: Week Six (Feb. 11-17, 2012)
This week, the Mechanical team assembled the shooter and finished drawing
the rest of the systems on CAD. We have started to assemble the drive train
and we are almost finished with that. We are putting together the rest of
the robot so that we have time to test the components to make sure that they
are functioning properly. Lastly, we helped with the parent presentation
with the other sub teams. This presentation will show our parents what we
have been doing for the past six weeks.
This week, the Business and PR team finished the essay and the questions for
the Chairman's Award and submitted the documents. We also finished the
website and submitted that as well. This week, Mrs. Hamada, Melissa's
mother, came to our class to teach us how to make buttons. We cut and
crimped the buttons, totaling over 400 buttons. This weekend, we have a
parent night presentation, so we prepped for that with all the other sub
teams. Lastly, our team made the videos for the Moanalua Scrimmage award
This week, the System Integration team updated and finished drawing all the
parts for our robot. Since it was crunch time, we mostly helped the
Electrical and Mechanical sub teams finish all the things that needed to be
done this week. We started a drop box account so that everyone on our team
could access our files. This week was extremely stressful, but we got what
we needed done.
This week, the Electrical team fixed some of the kinks our camera and
tracking programs had. It can now read the backboard from 20 feet away, and
can tell us the the distance of the hoop. The process is more consistent.
Overshooting the ball increases the chance of hitting the backboard. With
the massive amount of backspin on the ball, there is a good chance that it
will land inside the hoop. We prepared all the wires for the robot, so that
when the mechanical team finishes putting it all together, it is easy to
place on. Lastly, we worked with the other teams to plan and practice for
the parent presentation this weekend.
- The Mililani Robotics team does not simply compete in
the FIRST robotics competition; we also participate in community outreach
projects. Getting the public aware and involved is crucial to our success.
After all, the main goal of FIRST and our program is to promote interest in
the STEM fields.
FLL Competition: November 12, 2011
Mililani Robotics hosted a FIRST Lego League at our school on Saturday,
November 12, 2011. FLL is the elementary/middle school verious of the
competition that we participate in. Hosting this event gave us the
opportunity to work as a team and accomplish a large task.
