Triple Helix Tech Tips are an idea we’ve been mulling for a while. This is where we share our tips and tricks, which we hope will be useful especially for rookie teams. We’ve been around a while, and have learned some lessons, sometimes the hard way. Hopefully these will save you a little pain, a little time, and a little cash.
This project uses easy to find and affordable components to construct a Pulse Width Modulation signal generator that can be used to test motors and servos. The ability to bench test motors, subsystems, or prototypes without the need for RoboRIO or special software can save time. It is also a fun and and interesting project for the electrical team!
When we recruit new students, one of our favorite lines is, “Nobody who joins the team knows how to build a robot. We’ll teach you.” As an established team, we go to competitions and see younger teams, some of whom don’t have engineering mentors, struggling to learn lessons we have learned the hard way. We see our role in growing FRC as helping those struggling teams become better more quickly, so they remain inspired, and don’t fold.
Last fall our students came up with the idea of producing a series of instructional videos. These would teach our incoming rookies the skills they would need to be productive robot builders. We see this video series, and the ones which will follow, as a tool which can help educate inexperienced students on our own team as well as other teams across FRC.

Triple Helix presented at the Virginia Occupational Therapy Association’s 2018 School System Symposium. The focus of our presentation was how therapy professionals can use skills and tools of “makers,” including 3d printing, to make customized products for interventions with their patients. Our partner in this presentation was Maryland FTC team Green Machine Reloaded; this team presented on their work with the Go Baby Go program.
Abstract: “Makers” use the engineering problem solving process, and their hands, to bring their ideas to life. The competitive high school FIRST robotics teams Triple Helix Robotics and Green Machine Reloaded share the makerspace techniques to rapidly design and create assistive devices. The two teams will demonstrate the tools and technical skills used to 3D print small plastic objects as well as how to modify ride-on toy cars to create low-cost adapted mobility equipment.

Compiled by mentor Nate Laverdure in fall 2016, this document lists the top resources that have been helpful in his growth as an engineer and a mentor. They are representative of his interests and opinions, and therefore lean towards mechanical systems and fabrication techniques.
Taken together, they constitute his idea of an archive of fundamental resources (papers, presentations, videos, websites, etc) which are essential to being “good at robots” in modern FRC. The idea isn’t quite right– in truth, every team has the capability for designing and fielding excellent winning robots regardless of how well-developed their library of knowledge is. However, compiling these resources gives new FRC designers a significant leg up by rapidly exposing them from lessons learned from hundreds of people, some of them with over two decades of experience in this competitive robotics program.
The biggest thing to learn from these resources is simple: that nothing in FRC is so complex or far advanced that it can’t be understood by anyone willing to put in the time to understand it.
The crimp contacts used with the Anderson SB50 connector are sized for up to 6 AWG cable. Let’s swage them to fit 4 AWG!

After each competition, 2363 holds a “lessons learned” meeting where we discuss what we did right and what needs improving. One thing we noted was how awesome our airship pilot is. We noted that she makes better decisions than the audience. At the end of one match, our 3rd rotor was spinning, we had 4 gears needed to get the 4th rotor, and the horn sounded. Rather than waste time pulling up a gear with no value, she chose to drop the ropes instead. Of course the whole time the crowd was shouting, “Gear! Gear!” To honor her decision making skills under pressure, at our next meeting we presented her with a set of Airship Pilot’s Wings.
Has your airship pilot earned their wings?
