We’re building our first prototype. Photos are from 2025–26; code is on Benjamin-Dev. CAD, design rationale, measured test results and a new prototype demo aren’t posted yet.

01 / Mechanical design

2025–26 robot

Detailed view of robot 26910 chassis, motors, wiring and pink components — Chassis, mechanisms and wiring in our 2025–26 robot.

01 Challenge: Fit the mechanisms, motors and electronics into one robot.
02 Build: The photo shows the layout and pink fabricated parts.
03 Available now: Competition photos show the assembled robot.
04 Next: Add CAD, a design tradeoff and a before-and-after mechanism test.

02 / Shooting from different distances

Students using a laptop beside their robot — A team work session from our photo archive.

Shooter.java · Code excerpt

double distance = displacement.getMagnitude();
ShotProfile shotProfile = calculateShotProfile(distance);

Read Shooter.java

01 Challenge: Set the turret angle, hood position and flywheel speed as the robot moves relative to the goal.
02 Approach: Shooter.java calculates the distance and direction from the turret to the goal. It selects a short- or long-range profile, then interpolates hood position and RPM between set distances.
03 Available now: The code and tuning values are public.
04 Next: Add a field demo and shot logs by distance.

03 / Tuning the shooter

Test program

Robot 26910 at the field with team members behind it — Robot and drive team · 2025–26

ShooterTestingTeleOp.java · Code excerpt

telemetry.addData("Flywheel RPM", robot.shooter.getFlywheelRPM());
telemetry.addData("Target RPM", robot.shooter.getShooterConfig().flywheelRPM);

Read the tuning program

01 Challenge: Check whether the flywheel reaches its target speed while adjusting the turret and hood.
02 Approach: A test TeleOp lets us adjust RPM, turret angle and hood position. Telemetry and FTC Dashboard show actual and target RPM, each motor’s speed and robot position.
03 Available now: The test program is public.
04 Next: Plot actual and target RPM, then repeat a shot test before and after tuning. Record the conditions.
