2022 IRI application

Triple Helix students have proudly submitted the following application to the 2022 Indiana Robotics Invitational, a competitive and prestigious annual offseason FRC tournament in the Indianapolis area.

What competitions did you attend in 2022?

What was your best performance this year?

Triple Helix won our District Championship as the first overall pick of the event, and with a first-time robot driver. Over the season, we accumulated a 55-4-3 W/L/T record including a 27 match win streak and having gone undefeated at one district event.

Are there any special circumstances we need to know about?

Working with limited membership due to COVID, we focused on building the fastest possible Cargo cycling robot. With a simple robot design, and by devoting remaining time to practice and tuning, this strategy led to competitive success unprecedented for our team. We prioritized Cargo cycling to maximize points during teleop even during the last 30s; by ending matches with a buzzerbeater climb using an improved Everybot climber, we were able to rival Traversal climbers representing far greater resource investment and mechanical complexity.

During competition season, we selected and trained a new driver ~1 week prior to the DCMP due to an injury on the drive team. Triple Helix declined our invitation to the FIRST Championship due to travel restrictions by the school system.

Message from IIF on equal educational opportunities for transgender students

Triple Helix head coach Nate Laverdure sent the following message on behalf of the Intentional Innovation Foundation Board of Directors.

Intentional Innovation Foundation, the nonprofit operating sponsor of Triple Helix Robotics, strives to provide a safe, affirming, and professional environment for learners to explore tough, exciting problems in STEM.

We are disappointed by Tuesday’s [August 17, 2021] vote of the Newport News School Board to reject proposed revisions to Policy JB, Equal Educational Opportunities, which would have expanded the district’s existing anti-discrimination protection to the reasons of gender and gender identity. This change would have also enabled schools to implement policies consistent with the Virginia Department of Education’s “Model Policies for the Treatment of Transgender Students in Public Elementary and Secondary Schools” as required by law.

Adopting the proposed policy changes will make the school environment more reflective of the professional working environments of our employers and sponsors. This environment is one where contributions to the team matter more than identity based discriminatory factors, and it is an environment which we seek to provide to our participants. Adopting the policy changes enhances our ability to provide, at no cost to Newport News Public Schools, the high-energy competition robotics experiences which inspire our young people to become science and technology leaders.

Intentional Innovation Foundation advocates for the passage, without delay, of the proposed revisions to the Equal Educational Opportunities policy at the next Special Meeting of the Newport News School Board scheduled for Thursday, August 26, 2021, at 5 p.m. in the School Administration Building.

Be a mentor for Triple Helix Robotics!

Triple Helix Robotics is seeking mentors to help us level up our program!

Triple Helix is located in industrial Newport News, Virginia, a city where real people make real things. Ships, space vehicles, fuel injectors, photocopiers, particle accelerators– these things are conceived, built, and improved by rockstar designers, engineers, scientists, and technicians who live and work in our hometown. Our team aims to create the STEM experiences that transform students into these future rockstars.

Our team is distinguished by our two major passions: the iterative engineering design process, and good documentation. Together these two interests make us a constant and effective force in building a stronger youth STEM competition community. Our Peninsula STEM Gym, as well as the pre-season scrimmage event we run with partner teams 1610 and 5957, both provide unique opportunities for local teams to iterate on their solutions so they can be at their strongest at competition.

Our mentoring philosophies

Our team is relatively small, but our mission is large. Our core belief is that the most powerful way to engage our students in STEM is to provide a safe environment where they can experience complex problems in the form of a thrilling, challenging competition. We see our mentors as equal partners with our students as together we co-investigate those tough problems, forming awesome relationships along the way.

Desired areas of expertise

New Triple Helix mentors are not expected to know how to design and build an FRC robot– we can teach that! However, we are aiming to recruit mentors with the following expertise.

Math and physics

  • Multivariable calculus
  • Linear algebra
  • Ordinary differential equations
  • Classical mechanics

Control theory

  • Modeling of dynamic systems
  • Control of underactuated systems
  • Model predictive control (MPC)
  • Statistic filtering techniques (e.g. Kalman filtering)

Engineering and design

  • Mechatronics
  • 3D CAD (we primarily use PTC Creo and Onshape)
  • 2D and 2.5D CAM

Additional focus areas

  • Web development
  • Graphic design
  • Project management
  • Technical writing
  • Marketing

If this sounds like a group that you would like to join, please reach out to us at contact@team2363.org. Come build real cool stuff with us!

Triple Helix returns to flight with a FPV drone competition

As Triple Helix Robotics begins a new school year, our team leaders have been thinking about how we’ll accomplish the goals of the team– inspiring students with STEM– within the restrictions placed on us by the pandemic we’re all living through. In these slides, senior mentor Todd Ferrante explains the team’s current thinking in response to the continued public health crisis: this season, it’s up to us to create the spark of inspiration that will draw people– students and mentors– to participate in the team this year.

Triple Helix returns to flight by coming together to create the Tele Operated Robotics Competition– an internal tech challenge involving small bots which can be built by students at home and at the Peninsula STEM Gym, using the tools and techniques that are available to us.

How lead mentor transitions happen

One of the most critical existential risks for sustainable-minded teams (and the biggest single reason that teams “retire”) is the loss of their champion– the 1 or 2 key lead individuals who hold the whole thing together. In this presentation, head coach Nate Laverdure discusses how the outgoing lead mentors, the incoming lead mentors, the rest of the team, and the team’s stakeholder community can plan and execute a successful leadership change.

Question 309

Triple Helix’s 2019 robot used vision systems to target the retroflectors which were attached to various scoring locations around the field. Throughout that season, we struggled to find a way to use these vision systems without triggering the objection of nearby field volunteers, who found them to be too bright.

In February 2020, Triple Helix mentors posed a question in the official Q&A seeking a definition of the word “brief” as it appeared in the blue box below rule R8:

The question was deleted from the Q&A system soon after it was posted.

Our question, the original text of which is lost, was a non sequitur. We proposed the fanciful idea that since the manual describes the January-March build season as “brief” in a completely separate discussion of Vendor qualifications, then it must be acceptable to illuminate a high-intensity light for no longer than 3 months at a time.

The following email conversation tells the story of that deleted question. We share this conversation here because we think it remains an informative look into the thought processes of both the game designers and the players.

Hello Team 2363!

My name is Jamee Luce, and I am the Team Advocate for FIRST Robotics Competition. I’m writing to you today in regards to Question 309, one of the questions your team submitted to the official Q&A system.

Writing the FIRST Robotics Competition Manual is one of the most important, but most difficult, things we do as the Game Design Team. We try to balance its readability with the necessity to be very specific. This gets very challenging for us at times. As such, there are times when we use the same words to mean very different things.

In your question, the word “brief” is used in this way. In one instance of “brief”, we wanted to provide guidance to teams about how to appropriately use their vision tracking system, and in another, we used “brief” to describe the length of the build season.

We find the comparison of these two situations to be inappropriate, since most users will understand that we didn’t mean the same time frame in both instances. As authors of the manual, we need to be able to express ourselves in different ways, depending on the situation. In some cases, it’s imperative that we are very specific (how long can a team be pinned), but in others, we don’t believe our community needs that kind of specifics (have your light on for a brief period of time).

We have deleted your question, and we ask that your team please think about your questions and how it reflects on our community before your team posts again. Please remember that we are all members of this community together. Most of us are coaches and mentors ourselves, so we really do think about the manual in its entirety before we publish.

Thanks!

Jamee Luce, Team Advocate, FIRST ® Robotics Competition

Jamee, I appreciate your note and understand the group’s decision to delete the question. Thank you for personally reaching out to explain things.

I’m sorry the question was received as being inappropriate and caused you to see our team as not having a respect for the hard work of the team of manual writers. We think the GDC is doing a stellar job crafting FRC rulesets that are both clear and internally consistent. We do appreciate how exceedingly hard this is to do! Triple Helix has a deep love of high-quality documentation. We can point to the fact that there have been only a very small number of significant rule changes made this year in the Team Updates as evidence that the 2020 rules are largely well done. We also especially appreciated the decision to pre-release some limited rules sections prior to the start of the season, as this gave us time during the offseason to ponder over the implications of the 2020 bag day changes.

We are dedicated members of this community and are committed to the program’s effectiveness, especially in our local area. When we ask questions about the program, it comes from a place of wanting the program to be even better. When it comes to the particular issue we asked about in Q309, please understand that:

  1. Our team has a history with the limitations posed by the current manual language, at least as interpreted by the LRIs at our events:
    https://www.chiefdelphi.com/t/limelights-work-great-but-are-a-little-bright/350766
  2. We find that the potential for harm comes from a multiplication of two factors: intensity * exposure. As we do not currently have a method of controlling the light intensity, our strategy for mitigating risk relies primarily on reducing the 2nd factor in this equation, exposure. Ideally we can reduce exposure across both the space and time axes, by both (1) pointing targeting lights away from the eyes of field bystanders and (2) only lighting up the targeting lights while targeting the retroreflective vision target.
    https://www.chiefdelphi.com/t/limelights-work-great-but-are-a-little-bright/350766/31
  3. Although this mitigation strategy was successful in 2019, we are concerned that it will not be enough in 2020, given that:
    a. The goal is located above the opposing alliance’s driver station, putting the opposing alliance directly in the field of view of targeting lights. This takes away our ability to mitigate exposure on the space axis, leaving the time axis as our sole focus.
    b. It is reasonable for an alliance to be attempting shots on goal throughout most of the match.
    c. Even if not attempting shots on goal, it is reasonable to use lights and computer vision to employ the retroreflective target as one element of a field-relative positioning system throughout the entire match.
    https://www.chiefdelphi.com/t/anti-limelight-glasses-for-drive-team/371265/35
  4. We only sought GDC feedback after engaging with our community to the best of our ability. The origins of Q309 were in a discussion with Kevin Genson, the Senior LRI for FIRST Chesapeake, who wrote yesterday in a space for FIRST Chesapeake mentors:
    Hey everyone, just a reminder that the output of the Limelight cameras is very bright and can potentially run afoul of R8. On a recent LRI call there were a few examples of teams using the Limelight at full power and running it constantly during the entire length of the match. Please do not do this, as the moment someone complains about the brightness inspectors will be obligated to examine the light and may require mitigation. The best approach is to control the light via software. Ideally the light should only be used when targeting is happening; when the robot is facing the goal and you’re in the process of seeking the reflective strips. The Limelight software includes a lot of options and flexibility.
  5. Even if Q309 had been answered, we think it is unlikely this issue would be completely resolved, and we have a number of remaining questions about how brightness of lights will be managed in the 2020 season. For example:
    a. How can we help inspectors & field volunteers distinguish low-intensity lights from high-intensity lights on our robot?
    b. Are high-intensity lights legal if they are used (however briefly) for the purpose of locating the robot in 2D space instead of aiming a shot on goal?

In the future, how can we seek answers to these questions in a way that will demonstrate both (1) our respect for the large community of staff, volunteers, and players who make FRC work in a way that provides stellar experiences for our students and (2) our desire to seek improvements to relatively narrow aspects of the program that we believe could be improved to create even better experiences for our students?

Maintaining the important core mindset that we are all in this community together, would you agree with the idea that “the moment someone complains about the brightness inspectors will be obligated to examine the light and may require mitigation”? Do all types of complaints carry equal weight? If so, do you think teams using bright targeting lights are at risk of drawing any bad-faith complaints from opponent teams who would like to see these lights be shut off, but do not have a safety concern?

Are there ways to improve the safety of our robot lighting that you recommend we should consider?

Thank you and have a good weekend,
Nate Laverdure
