​​​Mechanical:

It's been an exciting week for mechanical developments of the robot. By Saturday, the team began testing the ball intake system.  After evaluating the intake on version four of the robot, the team determined that an additional motor was needed to increase intake power. Mechanical also focused on refining the components that improve the robot's ability to accurately launch and aim balls to score points, the spindexer. The team is enthusiastic about beginning drive practice next week!
The mechanical and software teams continue to work in close partnership, developing two robots simultaneously for efficient progress. While the mechanical team advances one version of the robot’s physical design, the software team develops code that enables the prior robot version to follow commands, recognize obstacles, and make decisions. Then, as software milestones are reached, the evolving robot body is handed off to the software team for movement optimization and performance tuning. The ladder development method enables incredible progress in a short time.

​​Software:

This week, the software team has embarked on several projects. First, they updated the turret code from last week and built improvements on that front. They also troubleshot the camera to ensure it can coherently scan AprilTags while running. Finally, to accommodate the multiple robots currently in development, they began coding for an additional motor. This will allow them to continuously adjust and affirm their action plan for the upcoming competition season.

​​Operations:

The operations team has been especially focused on prepping for Minuteman, creating merchandise for sale and promoting the event. As part of this effort, we've been more active in purchasing materials for pins and recently received a new pin maker, which will make production more efficient. Additionally, our team has prioritized outreach, connecting with parents and schools to arrange visits where we can show kids what robotics and STEM are all about.

This week, Team 4909 has continued to make strong progress on our build season goals, pushing forward across mechanical design, software development, and team operations. As we refine our robot and prepare for upcoming events, each subteam has stepped up to contribute toward our shared success
Picture

​​Mechanical:

This week, our mechanical team focused on advancing the robot's design and fabrication. We completed Version 2 of the robot, thoroughly troubleshooting its components and system to identify areas for improvement. Based on those findings, we started CAD work for Version 3, laying out updated designs that address performance and reliability. With the CAD work underway, we also began building elements of the V3 robot, turning our designs into physical parts ready for later integration and testing.

​​Software:

Our software team made progress on key control systems this week. A major milestone was the development of turret code, which enhances targeting and aiming performance for the robot. As with all complex systems, we ran into challenges throughout the process, so the team spent time troubleshooting issues as they arose to improve stability and ensure smooth operation during future testing.

​Operations:

On the operations side, we've been busy capturing and sharing our progress with the community. This week, our team focused on media production, collecting photos and videos to document build season developments for our social platforms and sponsors. In addition to this, we have started logistics for our upcoming competition, the Minuteman District event, which will take place March 7-8th at BMHS. We are actively improving our videography skills to create a robot reveal video that we will share with our sponsors. Finally, we're organizing outreach logistics to share what Team 4909 is doing and inspire youth in the community.
With each passing week, our team grows stronger and more aligned with our goals for the season. from mechanical improvements and software breakthroughs to showcasing our work through media and event preparations, Team 4909 is building momentum and demonstrating what we can accomplish together. Stay tuned for more updates as we continue toward competition!

Week 1 of build season is officially complete, and the energy is high as ideas start turning into reality. This is the week where plans take shape, teamwork is tested, and the foundation for everything ahead is set.

Mechanical:

Our Mechanical Team has been working diligently on the prototypes for this season. Hitting the ground running, we began CAD-ing a prototype turret launcher for this year’s challenge. In under a week, we moved from initial CAD concepts to a physical prototype, turning our ideas into reality. Our mechanical team is actively working with our software team on troubleshooting, testing, and refining the design.

​Besides the turret, they dedicated significant time to improving the drivetrain — the base of the robot — organizing wiring and preparing for additional upgrades. They are also beginning to integrate cameras to support vision on the robot. In addition, the subteam updated team equipment by bringing all programming laptops up to date and refreshing older robots so components can be reused or serve as backups if needed.

​Operations:

​Throughout the week, our operations team focused on documenting and organizing the team’s progress. They collected photos, videos, and updates from all the subteams to create media for all our social platforms and materials used in sponsor outreach. This work helps showcase our progress throughout the season and ensures sponsors can see the impact of their support. In addition, the operations team began designing and producing pins for the upcoming competition season.
​In just the first week, we have made significant progress and are excitedly looking forward to the rest of the season.

On Saturday, January 10th, Team 4909 officially kicked off the 2026 FIRST Robotics
Competition season at Billerica Memorial High School. Alongside alumni, veteran members, new members, and mentors, the team watched FIRST’s livestream of this year’s game reveal: REBUILT, presented by Haas. After the reveal, the team read through the game manual collectively to grasp the rules and objectives for the season and to begin developing a plan based on what was learned and prepared during the preseason.

In REBUILT, two alliances compete against each other to score fuel, cross obstacles, and climb the tower before time runs out. Robots can earn points by completing tasks across three periods
of play:​
Picture
To better break down the game and its rules, we split into smaller groups, with each group focusing on different sections of the game manual. This allowed new members to learn the basics while veterans and mentors shared insights from past seasons. We then came back together as a full team to discuss strategy, clarify rules, and build a shared understanding of how the game will be played and how we can approach it competitively.​
Autonomous Period (20 seconds)
The match begins with a 20-second autonomous period where robots operate without driver control. During this time, robots can score fuel into their hub, collect or shoot pre-loaded fuel, pick up additional fuel, and attempt an early tower climb for bonus points. A strong autonomous period helps set the tone for the rest of the match.
​
Teleoperated Period (2:20 minutes)
For the next 2 minutes and 20 seconds, drivers take control of their robots. Depending on what was achieved during autonomous, each alliance's hub alternates between active and inactive. When active, teams focus on scoring fuel; when inactive, they collect more fuel or play defense.
Picture
Endgame
In the final seconds of the match, all hubs become active, opening up full scoring. Teams can also climb the tower to earn major bonus points and improve their rankings. Climbing the tower involves reaching three stages, with each stage awarding 10 points. At the end of the match, the alliance with the highest score wins.

This year's field introduces several new challenges for teams, including the ramp and trench. Team 4909 has identified that navigating the ramp will be important to avoid getting stuck on fuel and that designing the robot to meet the height limit will be crucial due to the trench. Robots must also remain under the 115-pound weight limit.
Picture
To better break down the game and its rules, we split into smaller groups, with each group focusing on a different section of the game manual. This approach allowed new members to learn the fundamentals while veterans and mentors shared insights from past seasons. Afterward, we regrouped as a full team to combine what each group had learned, discuss strategy, clarify rules, and ensure everyone had a complete understanding of how the game works and how we can approach it competitively.

Picture
With a strong foundation in place, we transitioned into hands-on work to begin preparing for the season ahead. Members reviewed safety procedures, organized tools, and started early shop tasks to ensure we are ready to move efficiently into design and prototyping.

With kickoff complete, we are excited to begin strategizing, designing, and building as we work toward a successful 2026 competition season.
