Woodie Flowers submission 2019

Triple Helix students are proud to publish this Woodie Flowers Award nominating essay for our mentor Nate Laverdure.

Nate Laverdure joined Triple Helix six years ago and took on the role of head coach the following year. As a cryogenics mechanical engineer at Jefferson Labs, he is extremely valuable to the team as a whole, serving as the primary coordinator of Triple Helix activities in the community. As head coach, Nate has transformed the team’s structure to put students in leadership positions and has moulded the atmosphere into an incredibly friendly and inclusive environment. The relationship he has with students is respectful and comfortable, so much so that students refer to him by his first name. The amount of time and work he has dedicated to Triple Helix is inspiring to mentors and students alike.

Nate emphasizes the mentality of continuous improvement by organizing team meetings before and after competitions in which we reflect on the positives and negatives of our team’s performance at events. He also introduced System Integration Meetings, in which students from different subteams communicate their progress on team projects during the build season. These meetings maximize communication across the team and encourage students to communicate consistently in work environments. “Nate keeps everyone on the same page with emails and on slack, he leads the team in meeting about competition and makes sure everyone understands what’s going on,” says Sigrid.

Nate encourages learning by asking students to brainstorm how they would solve a problem rather than giving an outright answer. He motivates students through guided problem solving and ensures that students take on most of the projects and are recognized for doing so. “Nate makes the whole challenge and competitions less stressful by focusing on solving current problems instead of just winning,” said Eric. He also prioritizes assisting other teams in and out of competitions, sending pit crew members to other teams in need of a helping hand as well as collaborating with local teams in the off-season. To address the lack of practice space, Nate founded the Peninsula STEM Gym as a place where local teams can practice and collaborate.

At the start of each season, Nate presents the team with a list of priorities that need to be respected, including self, homework, and robotics. The purpose of this exercise is to establish a team mentality of balancing personal health and extracurricular activities. By impressing upon the students the importance of a balanced life, Nate encourages us to refrain from physical and mental overexertion, in the shop or at home. Nate serves as a model for students to emulate, as well as a resource, often teaching students physics and helping with other homework.

He’s influenced the team culture in a truly unforgettable and incredible way, provided a safe space for students to be completely expressive, and helped the team culture grow from that of a workplace into a family. Nate is not only our mentor, he is our friend.

Method for Arcade Drive input scaling

“Arcade Drive” is a popular joystick control method for skid-steer robot drivetrains, where one joystick axis controls the “throttle” (speed forward and back) and the other axis controls the rate of rotation of the robot chassis.

We provide a method for scaling the [-2, 2] range of (throttle command + turn command) down to [-1, 1] for use with an arcade drive.

This scaling is applied smoothly with no discontinuities anywhere in the input range. There is also no loss of information– both outputs (power/speed commands to motor controllers on the left and right sides of the drivetrain) always depend on both inputs (the driver’s throttle and turn joystick commands).

The Peninsula STEM Gym is ready for Deep Space
As a result of a special collaboration with FRC team 122 the NASA Knights, the Peninsula STEM Gym is now stocked with all the materials needed to build mockup wooden field elements for the 2019 FIRST Robotics Competition game Destination: Deep Space!

Attention woodworkers among us: we are seeking volunteers who’d like to use their building skills to help the local FRC teams by constructing these mockup game elements with us! Please contact us if you’re interested in joining the project.

Founded and operated by Triple Helix’s operating sponsor Intentional Innovation Foundation, and established with the generous assistance of a Community Knights GIFT Grant, the Peninsula STEM Gym is a place for student robotics teams to develop competition robots and have real-world engineering experiences that will inspire a lifelong interest in science and math. Our gym features a 75%-sized FRC field and a complete 2018 FIRST Tech Challenge – Rover Ruckus playing field sponsored by Newport News Shipbuilding. These resources are available for community use.

Thank you to the Community Knights
Triple Helix wishes to share our deep appreciation of Community Knights, Inc, which in December awarded our team a $2,000 GIFT Grant towards the purchase of a replacement metal lathe. In turn, our existing lathe will be passed to another competitive youth robotics team on the Peninsula, or moved to the STEM Gym to become a community resource.

Triple Helix students have the opportunity to learn how to safely use lathes to create high-quality robot parts. In this video we published over the summer, we document how our students use our current lathe to cut grooves for snap rings: small clips which retain components axially along a drive shaft.

Triple Helix earns another offseason win at Rumble in the Roads!
In early November, Triple Helix continued to prepare for the upcoming 2019 FIRST Robotics Competition season by competing at (and volunteering to help run) the Rumble in the Roads at Heritage HS in Newport News.  Triple Helix was ready to make a strong comeback in the elimination rounds after being bested in 5 of 6 qualification matches in early play.  We were selected by Team 836, the captain of the 3rd alliance, as their 2nd pick, and together with Team 623 we proceeded through three tough rounds of play to WIN THE EVENT!  This was Triple Helix’s fourth elims teamup with our friends at 623 in three consecutive seasons, and this time we finally came away with the win together.

Thanks to all who were able to visit and watch us on the live webcast– it was great to be cheered on by so many of our alumni, parents, and friends!

5th annual Rumble in the Roads a roaring success
In partnership with our friends at FRC teams 1610 and 5957, Triple Helix hosted the 5th annual Rumble in the Roads on Saturday, November 3.  Located at Heritage High School in Newport News, the event is one of the FIRST Chesapeake region’s premiere offseason FRC robotics competitions.  The event featured 31 high school teams from VA, MD, and NC who competed all day with their 140-pound robots.  Feedback from the event has been overwhelmingly positive, and we look forward to running an even better event next year!

The Rumble in the Roads is made possible by generous sponsors including Newport News Shipbuilding, Christopher Newport University, Canon Virginia, Swisslog, Community Knights, and Jefferson Lab.  The event is produced in partnership with FIRST Chesapeake, Newport News Public Schools, and Intentional Innovation Foundation.

Converting Festo’s flow rate spec to Cv

Festo gives the flow rate through their solenoid valves in terms of “standard nominal flow rate”. What does this mean? How does it compare with other valves on the market?

Here’s a spreadsheet that converts the specified flow rate (which is actually a mass flow rate even though it’s in units of volume/time) into a flow coefficient or Cv. This lets you directly compare the size of the valve to other vendors’ stuff.

What is the Peninsula STEM Gym?
Founded by Intentional Innovation Foundation, the Peninsula STEM Gym is a place for student robotics teams to develop competition robots and have real-world engineering experiences that will inspire a lifelong interest in science and math.  By enabling our students to better practice their sport in our Gym, we increase the likelihood that they can “turn pro” upon graduation.

We are excited to announce that the Peninsula STEM Gym now features a complete 2018 FIRST Tech Challenge – Rover Ruckus playing field sponsored by Newport News Shipbuilding!  This field was used last night for a scrimmage of 5 local FTC teams, organized by the Spegonauts at Hines MS.

How you can help
Community members wishing to contribute financially to the Peninsula STEM Gym are invited to sponsor a chair!

We are also recruiting a volunteer resource scheduler for the Peninsula STEM Gym.  This person would manage time slots for the key resources at the STEM Gym (currently, the FRC and FTC fields, and perhaps other users as the scope of the facility expands).  This role can be done mostly remotely, but will occasionally require visits to the facility to give a local team access to the space or check up on the status of the equipment.

In less than a couple months, we are also looking for volunteer field element builders who can use their woodworking skills to help the local FRC teams!  Using drawings that are published by FIRST during the FRC Kickoff in early January, these volunteers will construct full-scale wooden mock-ups of the major elements of the 2019 Destination Deep Space FRC field.  Here’s a past example of a field element that we would need to build.
