FRC Team 4048 Redshift

Westborough High School FIRST Robotics Competition Team 4048 “Redshift.” The following information describes the robots built in different season by my team, run by me as Captain in 2024 and a design team lead member in the previous years.

2024: Crescendo

FORTISSIMO

  • Retained SDS Mk4 swerve drives; upgraded from L1 to L2 gear ratio for increased top speed

  • Reduced robot footprint to 28" x 28" and limited height for unrestricted field traversal

  • Focused design on a subset of game objectives to maximize execution quality

  • COTS climber components to reduce development risk

  • Internal intake kept game pieces within the frame perimeter for protection against defense

  • Fast intake, driving, and shooting optimized for quick cycle times

  • Added LED indicators post-District Event 1 for drive team status feedback

  • Added swerve module boots to prevent game piece interference

  • Result: smaller, lighter, and simpler robot that outperformed previous iterations

2023: Charged Up

FERBINATOR

  • SDS Mk4 swerve modules with Neo motors for agile navigation and driving accuracy

  • Single-stage arm extension with pincher end effector capable of handling both cones and cubes

  • Robot height built to 1/4" below the maximum allowed limit

  • Frame perimeter set to maximum 120" (30x30) for stability

  • Two undercarriage pipes allowed the robot to overhang the Charging Station edge by up to 12", freeing space for alliance partners during endgame balancing

  • Provisions added for lidar and 3D camera for future autonomous and machine vision development

  • 32x32 LED panel added for driver-to-human-player communication across the field

2022: Rapid React

SPINISTER

  • 62% new students (49% freshmen); KOP 6-wheel drop center chassis used to accelerate build timeline

  • Vision-tracking turret with single-shot shooter and pneumatically driven loader

  • Single-ball-at-a-time intake for controlled feed

  • Climber: two double-segmented arms with strap winches and static frame-mounted latches; robust enough to hold the robot on a single arm

  • Weight reduction through less metal, smaller fasteners (10-32 vs 1/4-20), and carbon fiber intake
