All four squads of Chaminade’s Eagle Engineering robotics team, including the middle school’s team 83, advanced to elimination rounds at the Windward School Vex Robotics Tournament this weekend; with one squad emerging as tournament champion and another taking home their first judged award. This was the team’s first tournament of the year, resulting in one of the eagle units reaching their goal of qualifying for the State Championship in March.

The all-day event was also the debut of Chaminade’s first all-girl robotics team, 1138-G, who launched on a high note by taking home the Judges Award, given to the team singled out as deserving of special recognition.

Vex Robotics is the smaller of two robotics platforms in which the team competes, with robots limited to 18 inches in each dimension. Matches are played between two opposing alliances, each comprised of two unique robots with a team number specific to their school. Schools may field multiple teams by adding a letter designation to their team number, giving more students an opportunity to design, build and compete as a unit. Over the course of several qualifying rounds teams play in randomly assigned alliance pairings, requiring them to adapt quickly to each other’s unique abilities and style of play. Squads from the same school may play with, or against each other according to the luck of the draw during those rounds. However after qualifying is complete, the top 8 seeds are allowed to choose two partners to rotate in for the finals. The alliance captains may invite a team from their own school, or not, depending on their tournament strategy.

On this day, Chaminade’s team 1138-B (captained by Julian O’Neill ‘16, with drivers David Ardy ’17 and John Mosunic ’17) dominated throughout the day, going undefeated and landing in the top seed. They selected teams from Servite and El Camino Real as their partners for the finals. The 1138-A team (captained by Noah Hosaka ‘18 with coach Chris Grabow ’17 and driver Shail Desai ‘18) finished 5^th, but were bumped up to the second seed with a selection by another El Camino team. Chaminade’s middle school team 83 (driven by Eric Zhao ’20 and Daniel Ahn ‘20 with field coach Harry Bebedian ’20) performed exceptionally well against mostly high school teams, finishing 7^th in qualifiers and bumping up to the 4^th seed for the elimination rounds. Chaminade’s third high school squad, newly formed all-girl team 1138-G (captained by Nicole Kuberka ’17 with programmer Aubrey Dooling ’17 and a committee of drivers including Ariana Nicolau ’17 and Gioia Melian-Huerta ’19) finished 14^th, but rose to the 8^th seed during alliance selection. The entire roster of Team 1138 includes 70 students working off the field, filling essential roles from designers, builders, programmers, and support personnel to business, management and marketing staff.

This year’s game Nothing But Net is a fast-paced and exciting sport in which student-designed machines must shoot 4-inch foam balls into a net from as far as 15 feet away. The 1138-B robot led scoring with a very accurate and consistent shooter, with the crowd often cheering as they nailed full-court shots one after another. The robot design relied heavily on the students’ application of their physics education, well documented in their engineering log book full of projectile motion equations and test data. “The physics doesn’t lie. You could even say this is Dr. K’s ‘bot,” said Julian O’Neill. Their work earned the team a Design Award on top of their tournament win.

The playoffs began with brother versus sister as the 1138-B alliance faced the girls from 1138-G in the quarterfinals. After winning the best-two-of-three round, they moved on to face their younger sibling team 83, who went toe-to-toe with the high schoolers, forcing the round to three matches. The 1138-A Alliance also sailed through their side of the bracket, leading to a showdown between the two Chaminade teams. At that point there was no way Chaminade would leave without a state championship-qualifying victory. The final matches featured an impressive display of scoring from both sides, each match going down to the wire.

Both the A and G teams have no time to rest as they head off to Viewpoint School in Calabasas for the annual Clash in the Canyon tournament this Saturday, October 17.  Qualification rounds start at 8:30 a.m. and admission is free.

On February 14, Chaminade College Preparatory sent six teams in three divisions to the VEX Robotics Southern California State Championships held at the Pasadena Convention Center.

The middle school sent three teams to the VEX IQ division. After qualifying, Team 83C ranked 7^th, 83A ranked 23^rd, and 83B was 24^th. After the finals, 83C ranked 9^th, while 83A and 83B were tied for 10^th. Due to technical issues with robots, Team 83A performed a major reconstruction on site. They performed well in individual skills and autonomous runs, gave superb explanations and evidence for their STEM project “The Future of Space Exploration” and the design and engineering of their robot. They also demonstrated a high level of teamwork and respect. The judges chose Team 83A for the VEX IQ California State Championships Middle School Excellence Award.

In the VEX Robotics Design Competition (RDC) Middle School Division, Team 83 competed against some of the best middle school teams in the state, and in the world. They gritted a hard-fought 6^th rank after qualifying, and then formed a strong 4^th seed alliance with Joe Walker and Holmes International Middle Schools. Together they reached the semi-finals where they were eliminated by the No. 1 alliance. With a their strong 6^th rank showing at the tournament, 4^th place in programming skills, 6^th place in robot driving skills, as well as their demonstration of engineering design principles knowledge, the judges awarded Team 83 the California VEX RDC State Championship Middle School Excellence Award.

Finally, in the VEX RDC High School Division, Eagle Engineering sent two teams against the best of Southern California, including the defending VEX Robotics World Champions. After qualifying, Team 1138 and 1138B were ranked 27^th and 29^th respectively. It was a day full of technical difficulties for both teams, with Team 1138 judged while their robot was taken apart during troubleshooting. In the end, because of their superior documentation of their robot design process, a good showing in the robot skills challenge, and their impressive judge interview while explaining their troubleshooting process, Team 1138 was presented the California VEX RDC High School State Championship Excellence Award.

This is the first time in the VEX Robotics California State Championships history that teams from the same school have won the Excellence Award in all three divisions. Their win automatically qualifies them to the 2015 VEX Robotics World Championships which will be held from April 15 to 18 in Louisville, Kentucky. Nationally, close to 12,000 teams participate in the VEX Robotics programs throughout the year, with nearly 800 teams coming from California.

Congratulations Eagle Engineering Teams 83, 83A and 1138 – State Champions!
