hen school started in August, the Upper School computer lab was unrecognizable. Once a dark room filled with rows of computers, it now houses pieces of plastic, chunks of metal, tinkering teenagers and the robots they’re creating. Most of the equipment sits on tables scattered around the room. Student engineers loom over them. They talk about their robot, how to make it better, or an upcoming competition. Since time is fleeting, they move quickly. They run with sharp objects, mildly shock their fingertips on cut electrical wires, and sometimes accidentally break precious objects they designed and printed on the 3-D printer. A sign on the wall reads: “Shoes OFF. Goggles ON. Get to Work.” Two robotics teams call this room home. There are 10 students per team. The upperclassman robotics team, the Motorheads, has eight members, six girls and two boys. The underclassman team, Viridian, has two girls and six boys. Although they are not too competitive with each other, building robots side-by-side does lead to rivalry. “I’m biased, but I think my robots better,” said freshman Andrew Glick, Viridian lead designer. At competitions, teams of two compete in a game similar to Whirlyball. Robots race against the clock to toss wiffle balls into tubes of varying heights. Meanwhile, the student engineers hope all the programming is right and none of the pieces fall off. They figure it out as they go and take everything in stride. The team is made up of builders, programmers, a lawyer, and a marketing representative. Builders construct the robot. Concerning the electrical system, they must know how to distinguish between wire looms and grommets, how to place a ferrule on the end of a wire, and how to crimp the correct wires to operate the robot. When asked how they keep all this information straight, they’ll laugh and tell you this is just the basics. When some hear the word “robot,” they think of a futuristic, human-like figure that can clean your room or do your homework. These robots do not resemble humans. More often they are 18”x18”x18” boxes made up of metal rods and four wheels. Inside are two green and black scissor-lifts that move the machine up and down. The robots are built for functionality, not style. “It’s not meant to look fancy,” said junior Kevin Gonzalez. “Functionality is always top priority.” The programmers design the program that allows the robot to operate. They write the program in Labview, the computer software required by First Tech Challenge (FTC), the company that hosts the competition. The student lawyer, junior Raven Breitfeller, is responsible for knowing competition regulations. “She’s in charge of knowing the rules in and out and telling us what we can and can’t do and possibly coming up with ways to exploit them,” Kevin said.

can to raise money for the team. Juniors Madhuri Deo and Ruchita Iyer emailed local restaurants such as Smoothie King and Fuzzy’s Taco Shop to raise money that would go towards building the robot. In December, they plan to make a pitch to Texas Instruments (TI), for $2,000 towards competition, travel fees and robot parts. Madhuri and Ruchita must know the game rules and how the robot is built well enough to make a convincing pitch to potential sponsors. According to junior Tanvi Shah, captain of the Motorheads, one of the biggest challenges the team has faced so far is lack of time and experience. “I don’t know much about mechanics and pulleys and wheels and 3-D printing, and that is really hard. Especially when I’m in a time crunch,” Tanvi said. Kevin said he also feels that a lack of time and experience works against them. “What we really need is a lot of time. With [school], we just don’t have enough time. Four hours a weekend is a lot, but that’s all we can spare,” Kevin said. The students meet for hours on Saturdays and work on their own time during school. Students passing by see the room packed throughout the day. Kevin said he feels this time is necessary for the team’s cohesion as they build their robot. “We regroup because there’s a lot going on at the same time and sometimes information doesn’t get across. We make sure everyone knows what’s happening, what the game plan is,” he said. Robotics teams that have competed for longer often have more sponsors or help when building their robot, an advantage the Motorheads team is lacking. “There are groups that have been [around for] a much longer time so they potentially have more sponsors already,” Kevin said. “[Sometimes] they have professionals helping them,” Tanvi said. Tanvi became interested in robotics when Ms. Suarez, her advisor, brought up starting a team. Tanvi asked her friends to join. Kevin participated in a robotics team in Middle School and has good memories of his experiences. The robotics teams can compete in three levels of competition: regional, state and national. They can enter any regional competition but must qualify for state and national. They can win in several categories: performance in the game itself; best presentation in front of judges; best engineering journals; best team spirit. The journal is where they record their engineering process building the robot. “This is the first time and first year we are competing as a team. We don’t know what we’re doing most of the time. [We] really just feel it out, work our way through it,” Kevin said. The Motorheads team is preparing for a regional competition on Jan. 17 at University of Texas at Dallas. story by Madison Goodrich graphic by Anurag Kurapati data collected from Forbes and The Boston Globe
