Continuing to prototype the shooter, we were met with increasing levels of success. In the second test, we used expansion springs, allowing the motors to stretch the springs rather than compress them. Varying the number of springs in the tube, we were able to successfully launch the ball nearly to the ceiling, as well as into the goal from various distances. To test more combinations, we experimented with springs of different lengths and force constants. After reviewing our data and videos, we decided that the optimal design was with four six-inch springs that were used on Andy, our 2010 robot. Using these springs, we were able to shoot from a distance of 18 feet into the top goal. Later, we attached a potentiometer to the gearbox on our shooter to calculate the pull-back distance of the springs. This will be used to identify the exact expansion of the springs so we can optimize our shooting.

We finalized the design for our drivetrain and sent the CAD drawing to one of our sponsors, Gaum Inc., to machine some elements of our design. They will be machining the rails for our drivetrain in duplicate so that we can construct a practice robot alongside our competition robot.

The software team worked on coding various PID controllers.  We used a PID controller with a potentiometer to control the angle of an arm and another to control the pullback on a spring. We reprogrammed last year’s robot, Athena, to use a PID with a feedforward term to control the shooter.

The Nemesis marketing team has worked vigorously thus far in the month of January.  With the business plan in an acceptable state at the moment, the team has turned to focus on its newly-launched website.  Aside of the webpage, the marketing team now works to create and distribute new and improved promotional items..

Though the website is now fully-functional and updated with biographies, links to other social media sites and information regarding robots, many other features will soon be implemented including pages dedicated to spreading the FIRST message and directing fans to competitions.  The site now hosts numerous articles regarding team progress, outreach and success, allowing the elaborately-descriptive yet simplistically-interfaced webpage to generate togetherness within the Nemesis community.

Our team hosted their annual Robotics Discovery Day, an event where second through sixth graders worked with team members to create robots on December 7th and 8th. We had ninety-two camper’s gather at the technology lab excited to build a robot and drive Nemesis’ 2013 champion robot, Athena.

The younger campers were participated in a Ping-Pong Ball Challenge. Campers created remote-controlled robots that launched ping pong balls as far as possible. Students Ava Blando and Ruhi Dua designed the winning robot that launched a distance of 78.5 inches. Experienced campers completed the NXT LEGO® Mindstorms Basketball Challenge, building robots able to carry and shoot pin-pong calls into a basket using ultrasonic and touch sensors. With a time of 1.17 seconds, campers Luke Delcampe and Gurveer Grewal won the challenge.

We had a great turn out, a fabulous review from parents and the campers can’t wait to come back again.

December 9th-15th, 2013 saw Computer Science Education Week, an annual event dedicated to sparking an interest in computer science in kids K-12. It also marked the official launch of Code.org’s “Hour of Code”, in which the organization asked teachers to dedicate one hour of class time to learning about computer science and programming. With the help of Microsoft and Apple and support from President Obama and House Majority Leader Eric Cantor, over 15 million students participated in the online programming tutorials, 51% of whom were female.

This program came just in time, too, for according to Rip Empson (writer at TechCrunch), 9 out of 10 schools in the U.S. don’t offer computer programming classes. A need for more accessibility to coding and computer science is just one of the reasons Team Nemesis works tirelessly to spread awareness of STEM education.  At the team’s annual Robotics Discovery Day, kids in grades 2-6 not only construct their own robot, but learn to program their creation using LEGO Mindstorm technology. In 2012, New Jersey Senator Linda Greenstein and Assemblyman Daniel Benson issued Nemesis a Joint Legislative Resolution, recognizing the team as a program that spreads STEM education throughout the community.

Luckily for member of Team Nemesis, the local high school offers a wide range of Project Lead the Way, technological design, and computer science classes to students in all grades. In fact, Robbinsville High School has been nationally recognized for fostering exemplary Career and Technology Education programs. Furthermore, due to Team Nemesis’ tremendous success, Project Lead the Way courses have been introduced to the local middle school, requiring all eighth graders to take at least one technology course before matriculating to the high school.

So, interested in learning to code? Visit Code.org for more information.

It is winter, the holidays are over and people are still hungry. To the rescue is the Robbinsville Food Pantry, the students of Sharon Elementary School and Nemesis, Robbinsville High School FIRST Robotics Team 2590. To stock the shelves they hosted their biannual food drive, collecting canned goods, nonperishables, and personal hygiene items. Sharon and Windsor Elementary Schools generously donated items and Nemesis team members sorted and delivered them. The food drive was led by Stephanie Kovacs, Erica Falk, and Samantha Young.

“It feels really great to give back to the community.” said Samantha Young, a sophomore and member of the Nemesis Build Team.

“It was exciting to see the reactions of the kids when I went to pick up the food.” says Erica Falk, a senior and member of the Logistics team.  

“I have heard that people got laid off. We don’t really think that it affects us, but it does. You do what you can to help. ” says Mitaali Taskar, a sophomore and member of the Marketing Team.

It is important to Nemesis to help out the community that supports our team and we highly encourage everyone to donate to the Robbinsville Food Pantry throughout the year. The food pantry is located at the rear of the Robbinsville Senior Center at 1117 U.S. 130, Robbinsville, NJ 08691. Please contact Renee Burns via e-mail at Renee@robbinsville-twp.org or phone at (609) 259-1567 for more information.

After attending kickoff and becoming more familiar with this year’s game, Aerial Assist, we returned to our school for some preliminary strategy and game analysis.  Determining that we would need to construct a robust robot capable of picking the ball off the floor, rotating it up toward the target, and shooting from a decent distance away from the goal, we began sketching ideas. Gathering many possible designs, the team began to CAD their ideas so that they could be translated into prototypes.  

We started prototyping by breaking into two groups: shooter and intake. For the shooter, we tested a spring-loaded linear punch mechanism. The first design that we tested involved compressing springs within an aluminum tube. Unfortunately, the springs wanted to be in their longest state and ended up bowing within the tube.

 Additionally, we prototyped several variations of claw mechanisms for our intake. We started with a three prong mechanism—two prongs on the bottom and one of the top with a roller. In parallel, we built an intake that grabbed the ball from the sides and had two rollers to control the ball. After creating these prototypes, we decided that we needed a floor intake that would be able to change angles to shoot and a shooter that could vary its power.

We decided on an eight-wheel drivetrain which would be an updated version of a drivetrain that we had developed over the summer. The drivetrain included eight four-inch traction wheels with the center wheels dropped which would allow for easier mobility. The wheels will be run by timing belts which will be fully inclosed within the rail. For gearboxes, we plan on using VexPro Ball Shifters.

Robbinsville High School (RHS) Robotics Team FRC 2590, Nemesis, hosted their annual Discovery Day Robotics Camp, an event welcoming second through sixth graders to work with team members to create unique robots. On Saturday, December 7th and Sunday, December 8th, ninety-two excited campers gathered in the RHS Technology Lab to learn more about engineering and design from Nemesis team members and mentors.

When given the opportunity to drive Nemesis’ 2013 robot, Athena, participants vibrated with excitement.  “It was really cool—I liked building the robot and driving the robot,” gushed Atishay, a second grader. With assistance from Antonio Papa, lead programmer, students took Athena for a spin, aiming and shooting Frisbees into the high scoring goal.

Younger students participated in the Ping-Pong Projectile Challenge. Participants created remote-controlled, motor-powered robots challenged to fire ping pong balls the furthest. Students Ava and Ruhi designed and engineered a robot that launched the ping-pong ball an impressive distance of 78.5 inches.  Griffin, a fourth grader,  made the suggestion “messing around with the trajectory a little bit” which improved his machine.

Choosing from a variety of sensors, experienced campers completed the NXT LEGO®   Mindstorms Basketball Challenge, building robots able to carry and shoot ping-pong balls into a basket.  With a winning time of 1.17 seconds,  campers Luke and Gurveer programmed and tweaked their robot for success.

Discovery Day provided participants with a new perspective regarding Science, Technology, Engineering, Mathematics, and Computer Science (STEM). Students successfully learned the importance of not only creating a good design, but how to approach solutions to difficult problems. “There’s a lot of error in making a robot,” explained fifth grader Kavya. “You have to troubleshoot.” Steve David, father of a satisfied participant, enthused: “thank you to you and all the students that ran the program—it certainly presented a compelling picture of a career in engineering [for my son], and in my opinion, was an overwhelming success.”

Discovery Day prompted excitement from both participants and Nemesis team members alike.  Several other students expressed their excitement for next year’s program, leaving with content smiles. The event serves as one of Nemesis’ largest fundraisers, allowing them to travel and therefore compete in regional and international competitions.

THE MESSENGER-PRESS: Amy Batista

ROBBINSVILLE — The Robbinsville High School FIRST Robotics Team 2590 Nemesis received $4,000 in donations during the board of education meeting on Nov. 19.

Debi Bella, President of Robbinsville Education Association, presented a check to the FIRST Robotics Team for $2,000 prior to the start of the meeting.

”We’re so excited to be able to make a donation to such a worthwhile program,” said Ms. Bella after the meeting.

This was the first time the REA has made a donation to the robotics team.

”We’re trying to expand our outreach programs,” Ms. Bella said. “It’s just great to see how far they’ve come and what they’ve been able to accomplish.”
Tom Staab, first vice president of the REA, was happy to support the team. “I’m glad to come back and see where the kids are now,” said Mr. Staab “It’s cool to see the next level of the program.”

Mr. Staab said the seniors coming through never had the opportunity to do robotics in the middle school, which was just started within the past few years.

Team advisors are Joy Wolfe and Scott Meredith, who are both technology teachers at the high school.

Joshua Falk, 17, of Robbinsville is the CEO of the 56-member team, which is broken down into different subsections.

”Our team is split up into half marketing and finance and the other half is build,” said Baljot Ranu, 16, of Robbinsville, CFO of the team.

According to Baljot, the team is set up “like a business.”

”We try to include almost like a Fortune 500 company – we have a build side and a then a working finance team,” Baljot said.

The team is looking to generate more interest in science, technology, engineering and mathematics among kids and have fun while doing it.

”Basically our goal of FIRST is to generate more interest and get more kids involved in science and technology,” said Joshua, who further noted that each year the team is assigned a different game or task and has six weeks to complete the challenge to build the robot.

”We compete over a few months,” Joshua said. “The past two years we’ve been really fortunate. We’ve done really well.”

The team has competed in Region Championships at Lehigh and at World Championships in St. Louis, Missouri.

”Last year we actually we won the Mid-Atlantic region and we were voted twelfth overall in the world,” Joshua said. “We’ve done really well recently and we are hoping to keep that up.”

The game this past year was “ultimate ascent,” which included shooting Frisbees into goals, which varied at different heights and for different point values and also included a metal pyramid the robot could climb for “bonus points.”

Baljot said there is a “strong” connection between the technology curriculum in the classroom and the robotics club that meets after school.

”For a lot of the build team members, we go through project lead the way courses at our school which is pre-engineering series of classes,” Joshua said. “We learn how to design, solve problems, introduction to engineering and things like that and how to use computer-aided design (CAD), which is the 3-D model.
”We are really lucky to have our school support as well as our sponsor support,” Baljot added.

Sponsors who support the team throughout the year include but are not limited to – Robbinsville Board of Education, Robbinsville Education Foundation, CCL Label, New York Society of Cosmetic Chemists, Siemens, Citibank, Elite Dental Care, Carfaro Inc, Gilbane, McGraw-Hill and Guam Incorporated.

We thought none of this was actually possible,” Baljot said. “That’s why we’re really lucky to have all of the support.”

The team is working on organizing a sponsor networking day.

”We love that day,” Baljot said. “Our sponsors get to come in and actually see what we’ve done and the support they’ve given us.

”Overall it has helped me so much,” she added. “I came into this team thinking I was going to build a robot and after the first week I saw a whole other side of it and I got interested in the marketing and finance.”

She said because of her experience with the team when she walked into her college interviews “she feels prepared” and that the interviewers take an interest in her being in an “interactive club.

”I get a real life experience,” Baljot added, as she explained how she is accountable for money and budgeting finances of the team unlike other clubs she is in.

For the students, working with people who work in the field doing it for a living find it “cool.”

”The coolest thing it is all student done and student run and mentor advised in addition to our two technology teachers who at the school but then people’s parents who engineers or programmers or in marketing who come by after school and help us,” Joshua said. “We are actually working with people who do this for a living. That’s really cool.”

In addition, to the REA contribution, Lockheed Martin also donated $2,000.

In an environment where technology’s influence on the world is rapidly growing, progressive companies strategically utilize robotic devices and concepts to optimize supply chain and business efficiency, but ultimately to enhance human lives. Robotics design, construction, and application have endless possibilities. Through software and programming, robots are capable of accurately executing difficult tasks and optimize processes.

FIRST Robotics is a program that annually challenges STEM students to create a problem-solving robot by implementing the Engineering Design Cycle. This process involves brainstorming to capture ideas and generate potential solutions and strategies. Through CAD (Computer Aided Design), innovative 3D designs are created to virtually test how components function together; this is both cost-effective and efficient. The best CAD-modeled prototype is brought to life and fabricated with computer driven machines and techniques. The robot is then assembled and refined through extensive testing and ultimately, a successful product is made.

The use of robotics engineering is globally revolutionizing how organizations compete. Concepts of the design cycle can be applied to many industries including Personal Care & Cosmetics. Rapid prototyping leverages a company’s competitiveness and enhances speed to market. Educational programs worldwide promote the Design Cycle and robotics because they transform ideas into tangible products and solutions. Due to CAD and the latest technologies, the “gizmos and gadgets” of science-fiction dreams are becoming a reality in our everyday lives.

Concepts of Robotics technology will be featured at the 2013 New York Society of Cosmetic Chemists Technology Transfer Conference, Iselin NJ.

Robbinsville High School FIRST Robotics Team 2590, Nemesis, presented to the prestigious New York Society of Cosmetic Chemists.

Nemesis arrived first at the Renaissance Woodridge Hotel in Edison, New Jersey with Josh Falk, Baljot Ranu, Uddhav Joglekar, Arnav Vast, Jolia Thadal and Parth Mandrekar representing the team.  We proceeded to erect our booth within our designated area of convention.  Due to greater attendance than expected, the NYSCC lacked nametags respecting Falk and Joglekar. Though inconvenienced, Nemesis performed cleverly and with clear preparation: when asked for business cards, Falk and Joglekar presented them swiftly confidently.

After enjoying a generously-provided breakfast and aweing its audience with Athena and effective multimedia video by Karla Dimatulac, all received an invitation to the conference room where highly-involved and renown individuals provided presentations regarding their fields, totaling four. Provided information proved phenomenal and diverse from the Human Genome Project to the Importance of Innovation lectures. Team 2590 received exposure to professionally-conducted projects and extensive concepts prevalent globally. 

Following the conclusion of presentation three, Nemesis enjoyed a spectacular and appreciated lunch, followed by an extensive period of marketing.  Though launched with sparing attention, the effort eventually received bombardment by a myriad of individuals and organizations interested in the establishment. Team 2590 operated with unquestionable efficiency and deliberacy, highlighting the Design Cycle, enticing listeners from lectures regarding the kickoff to the competition. Vigorously answering questions varying interminably regarding topic complexity, Nemesis members conveyed its overarching messages to their attentive audience:

• Nemesis requires more than technologically-adept individuals to function: this corporation requires both marketing and financials to operate effectively—and at all

• Nemesis comprises itself with diversity regarding gender, interests, sociality and ability

• Nemesis desires no less than to produce the most victorious and effective robots possible

Concluding this incredible event, the NYSCC generously awarded Team 2590 one-thousand dollars toward team funding. The Robbinsville High School FIRST Robotics Team honors the New York Society of Cosmetic Chemists for invitation and truly appreciates their patronage.

Congratulations, Team 2590!

For the past year, Nemesis competed with a frisbee-shooting robot named Athena. Over the summer, the team decided to build an additional full-court shooter robot, dubbed Nemesis Beta 2690. With a fresh set of members and a new robot, the team competed at this year’s Brunswick Eruption, an off-season robotics event hosted by North Brunswick High School.

Qualification matches were brutal. Entering its ninth competition, Athena was accustomed to harsh defense—almost 120 matches worth. The conditioned robot was constantly bulldozed into the pyramid, on top of already facing a rough day with unexpected problems.

“I saw it all through my camera and I captured every moment. When Athena went to hang, you could hear the pneumatic arms hiss, but she was not elevated when the buzzer sounded. When it was time to clear her from the field and Josh saw what went wrong, he burst out laughing. The breaking of the piston was inconceivable,” senior Stephanie Kovacs recalled.

“No one thought that this would ever happen. It is extremely unlikely to have a piston fall off,” Christian Gavalchin, a build member, expressed. But the drivers didn’t let this setback get to them. In a stunning turn of events, both robots seeded within the top eight by the end of the qualifying rounds—Nemesis at first seed with Beta following closely behind at fifth seed. An opportunity rose for our main team to choose our very own rookie once again.

In the end, Nemesis and Beta finished the competition as semifinalists. Despite the mishaps, the team was satisfied with the strong conclusion of the 2013 season. Brunswick Eruption brought the era of Athena to a close and marked the beginning of her well-deserved retirement. Along with her battle scars and amputated limbs, Athena will live on.

After a summer of working on a new robot, Robbinsville High School’s robotics team entered their first off-season competition.

Team Nemesis built a second competition robot for the game Ultimate Ascent, a challenge in which robots aim to shoot plastic discs through targets of varying heights and then climb a metal pyramid. While the team’s first robot, Athena, scoops up the disks off the field and shoots them straight into the top-scoring goal, the second robot is equipped with a full-court shooter.

On Oct. 12, while many RHS students were preparing for homecoming, the team traveled to St. Joseph’s Catholic School in Flourtown, Pa. for GirlPOWER. This competition required completely female drive teams and pit crews.

Nemesis’ new robot made its competition debut during the qualification matches. With the help of both robots, the team claimed second seed and chose Team 11 MORT from Mount Olive to join their alliance for elimination rounds.

The two teams moved through to the finals undefeated.

In the finals, best two out of three rounds determined the victors of GirlPOWER 2013. With one win already, Nemesis and MORT needed one more to clinch the crown.

With the sound of the buzzer, 11 disks autonomously launched into the highest goal, the robots relying on their pre-programmed instructions for the first 15 seconds of the match. When it came time for the drivers to set up, Athena and MORT dashed off to collect disks. Meanwhile, the full court shooter set up camp at the other end of the field, shooting disks into the highest goal.

Nemesis and MORT scored more than 100 points and were named champions.

However, the day wasn’t over yet. The team rushed back to Robbinsville, exchanged their t-shirts for dresses and celebrated their victory at the homecoming dance.

Nemesis’ next competition is Brunswick Eruption, scheduled to being 8 a.m. Nov. 9 at North Brunswick High School. Admission is free.

With the first week of school behind us and fall well underway, Nemesis is gearing up for the 2014 Build Season. The team will have a booth set up for the Club Fair on Tuesday, September 17th, where interested students can come learn more about Nemesis.

A mandatory parent and student meeting will be held for all those interested in joining the team on Wednesday, September 18th at 6:30pm in the Technology Lab. Whether your interests are building, programming, or marketing, Nemesis has a niche for you. We hope to have you join us for another season of fun and excitement!

The Indiana Robotics Invitational, IRI ,welcomed 69 world class teams to participate in the 2013 FIRST competition, Ultimate Ascent. IRI’s game however, tweaked rules and regulations to add a measure of excitement. Nemesis, FRC Team 2590, was Robbinsville, NJ’s contribution to the event. The team packed their bags, and headed out at 6:00 am, enduring a 12 hour car ride to Indianapolis. Upon their arrival, members unpacked Athena and organized the 8 square foot pit that would become their home away from home over the next two days. Within that square, team members would operate on the robot, sometimes calmly, while other times scrambling frantically. The long day ended in the hotel with the smell of local pizza and the sound of anxious chatter.

The sun rose and the first day of qualifications was up them. That morning, the lobby of  the hotel, packed with robotics kids from all over the country (and Canada), buzzed with excitement. Everyone eagerly awaited the start of the long day of 104 matches ahead. Despite their tough schedule, Nemesis was confident of victory. IRI was advertised as a competition featuring the “Best of the Best”. It was amazing to see some of the best robots in the world playing on the same field. With the outstanding caliber of the competition, most alliances scored in the triple digits and many scored over 200 points. With their 7 disk autonomous routine and precision scoring, Nemesis showed that it belonged among the august group. To become more versatile, 2590’s software architect, Antonio Papa, wrote a midline autonomous routine, a different spin on the strictly 7 discs under the pyramid routine used all season. This new program was implemented several times throughout the day with great results. Aside from some minor fix ups, the day ran smoothly. Athena suffered no major catastrophes or serious damages. Led by Stephanie Kovacs, Team 2590 participated in a group scouting, run by Team 20. Thanks to FRC Team 20, Nemesis members took short shifts and had the privilege of participating in a large scouting program. In the last match of the day, Nemesis’s alliance scored a competition high of 254 points, winning 254-129. By the end of the first day of qualifications, drive team members Josh Falk and Antonio Papa had guided Nemesis into 12th place with a record of 4-2. Nemesis celebrated the conclusion of the day one with a Mexican dinner, and a long discussion regarding scouting results and strategy.

The third day in Indiana brought the qualification matches to a close. Nemesis ended with a record of 5-4 and a final ranking of 23rd out of the 69 teams. During alliance selection, Nemesis was selected as the third robot to join third seed alliance captains, Team 469, Las Guerrillas, and their first round pick, Team 118, the Robonauts. 3847 - Spectrum was the fourth alliance partner. Due to the opponent's full court shooter, the first elimination round was played by 3847 because of their defensive abilities. The alliance acquired a win but Las Guerrillas, 469, was broken and could not play in the next round. 2590 stepped in and played the second match. Unfortunately, this match did not go well for team Nemesis. Halfway through the match Nemesis collided with Team 1477 and the resulting impact disabled both robots. With Nemesis down, the third alliance lacked sufficient firepower to overcome their adversaries. With one win on both sides the fate of the third alliance rested on the tiebreaker, but with two damaged robots, the outlook was grim. 469 went back on the field in an attempt to recreate their previous victory. Alas, their efforts were in vain. At the conclusion of the tiebreaker, the third seed alliance was no longer in the running to win IRI. Despite the loss, the members of Nemesis watched on, excited to see the winning alliance. The day came to a close. The first seed alliance took the title of IRI champions.

Despite the unending efforts from the team, Nemesis was not able to secure a win at IRI. However, they were not without success. 2590 went home as the only team to represent the Mid-Atlantic Region in the elimination rounds at the Indiana Robotics Invitational. The trip gave the students a chance to work together and improve Athena even when competition season was not in session. Representing Robbinsville, a little town in New Jersey, Nemesis partook in one of the fiercest, most competitive, FIRST Robotics competitions the world had to offer.
