LigerBots Host Newton Qualifier FLL Tournament and STEAM Expo
December 1, 2022

On Saturday, November 19, the LigerBots hosted the FLL Qualifier, a LEGO robotics tournament for middle and elementary schoolers. Eighteen teams of younger students from throughout Massachusetts came to compete in fun, fast-paced matches refereed by LigerBots students. The sound of the MC announcing the matches over the background music, a sea of colorful custom T-shirts, and LEGOs scattered throughout the school—this was the scene of the event, which was almost back in full swing after losing momentum from the pandemic.

Running alongside the Newton FLL Qualifier, the annual LigerBots STEAM expo was a huge success! LigerBots offered eight hands-on activities, and there were several outside exhibitors, including the Massachusetts National Guard, Green Newton, and Johnson String Instrument, as well as high school groups such as the NNHS Programming club, NNHS STEMentors, NSHS Science team, and NSHS Women in STEM. More than 100 kids engaged in a variety of STEAM activities and demonstrations. Among the LigerBots activities, approximately 100 binary bracelets, 100 balloon cars, 100 origami double pyramids and tangrams, 50 cups of slime, 20 solar ovens, and more than 100 custom buttons were made.

NNTV, Newton North’s student-run television station, interviewed several LigerBots and FLL students during the event. Team member Kavin talked about the little moments that made the LigerBots fun for him, like playing soccer with fellow team members. With teammates Kevin and Roshan, Kavin also talked to NNTV about LigerBots’ core values and a basic rundown of FLL and the STEAM Expo. Despite his now sore throat, Kavin had an awesome time giving his thoughts!

On November 6, The LigerBots unveiled two pumpkin-smashing machines for Newton’s annual Pumpkin Smash, an event at City Hall that encourages residents to compost their pumpkins in the best way possible—by throwing, tossing, or crushing them!

Both machines featured massive sledgehammers to obliterate pumpkins, though with slightly-different mechanisms: the first utilized our 2020 robot pulling a rope to trigger its sledgehammer, and the second used balls thrown from our 2022 robot to push its hammer down.

LigerBots students worked tirelessly the past few weeks to design and build the machines. With the guidance of veteran members, first-years learned essential skills in design, prototyping, CAD (computer-aided design), and manufacturing to create the pumpkin-smashing mechanisms.

During Pumpkin Smash, onlookers watch in awe after one of our smashers destroys a pumpkin.

Alongside destroying hundreds of pumpkins, the LigerBots also led a booth for children with hands-on STEAM activities, including our popular binary beads and origami activities.

With the help of LigerBots members, children create bracelets encoding short messages using morse code during Pumpkin Smash.

After the event, the crushed pumpkins were composted by Black Earth Compost to nourish the city’s soil. An estimated 750 to 1,000 Newton residents attended the event, making it a smashing success!

On Monday, November 7, we launched our annual Mock Three-Day Design process, an activity that brings first-years, veterans, and mentors into the engineering process in preparation for kick off in January. Over three Mondays, design groups will brainstorm, negotiate, organize, and present ideas in robot mechanisms that will help the team during competition season. We can’t wait to see what groups will come up with!

All team members not involved in Mock Three-Day Design are currently preparing for the upcoming FIRST LEGO League (FLL) Newton Qualifier, a LEGO robotics tournament for elementary and middle schoolers. We invite you to come cheer on local FLL teams at this year’s event, which will be on November 19 at Newton North. A STEAM Expo, featuring hands-on science activities for children, will also be hosted. Read here for more information about FLL.

LigerBots continues going strong in team training and fall projects. Engineering students—including many first-years—are upgrading our drivetrain (the mechanism a robot uses to propel itself) to increase freedom on the field and improve modularity compared to past drivetrains. New programming students are beginning to use Java to help program this drivetrain. In the CAD group, first-years are learning basic CAD skills in preparation for a CADathon—a short, collaborative CAD event—over Thanksgiving break. Marketing students are working on contacting clubs and companies to promote our upcoming FLL STEAM Expo, which will happen concurrently with the FLL Tournament. And, in the graphics group, students are developing visual materials for the upcoming First Lego League tournament, including a STEAM flyer for a DIY gimbal activity.

Finally, an exciting announcement—for the entirety of November, the LigerBots’ accomplishments are on display at the Newton Free Library! Come see our two displays, located next to the main desk on the first floor. Thanks to the graphics group for designing the displays! Read our announcement here.

LigerBots have an Awesome Time at N.E.R.D.!

On October 22, twenty-five LigerBots attended the first annual New England Robotics Derby (N.E.R.D.), an off-season robotics competition hosted by fellow FRC team Billerica Bionics at Billerica Memorial High School. We competed alongside twenty-seven other teams. 

N.E.R.D. was a great experience for our new members to get a feel for the FIRST Robotics Competition atmosphere. They helped set up the game field, learning about how large-scale field elements, like the climb assembly and driver stations, can be broken into smaller parts. Grasping driver and troubleshooting skills, several first-years also assisted in driving the robot and repairing it between matches. LigerBots students also met many other teams and learned about their different robot designs and strategies. 

In preparation for a match, the drive team sets up the drive computer.

Our team did a fantastic job by making it to the quarter-finals. More importantly, this event was an incredible learning experience for learning the ropes of competition, including field setup, pit repair, teamwork, and “coopertition”—cooperative competition.

As always, great thanks to our sponsors Newton Schools Foundation, Newton Public Schools, Eastern Bank, MathWorks, Paytronix, Raytheon Missiles & Defense, Rockwell Automation, Teradyne, Village Bank, Honda Village, Rotary Club of Newton, IvyMath, the Willins, and the Schwartzes. Your support is greatly appreciated!
