Robot Engineering

The 2025–2026 robot remains the clearest record of how the team converts requirements into tested mechanisms and software.
ARCHITECTURE

One robot, six connected systems

SYS / 01

Intake

A full-width, double-sided sweeper used multiple driven contact points and printed guides to reduce alignment sensitivity.

SYS / 02

Transfer

A linear indexer and differential transfer sorted and moved artifacts into the shooter in roughly 0.4 seconds.

SYS / 03

Shooter

A two-wheel servo turret rotated through 360 degrees while an adjustable hood changed launch angle by distance.

SYS / 04

Vision

Limelight AprilTag detection supplied field-relative position and goal alignment information for assisted aiming.

SYS / 05

Drivetrain

A compact mecanum chassis balanced lateral mobility, protected electronics, low mass, and between-match access.

SYS / 06

Autonomous

Close and far routines combined Pedro Pathing, tuned PIDF control, OpenCV decisions, and Bézier trajectories.

TEST DATA

Iterations that changed match performance

55% faster cycles

Stationary shooter to servo turret

The original shooter forced the drivetrain to aim. Separating turret heading from robot heading reduced alignment time and preserved the driver’s movement options.

30% faster transfers

Spinning indexer to linear indexer

The first indexer added delay and inconsistency. Linear motion shortened the transfer sequence and gave software a more predictable state.

Four versions

Narrow pickup to full-width sweeper

Bench and field testing exposed jams and narrow alignment tolerance. Wider geometry and revised guide angles improved centering and recovery.

PROCESS

The BioBuzz engineering standard

01

Define

Translate game rules and strategy into measurable requirements and failure conditions.

02

Model

Compare concepts through calculations, CAD, packaging studies, and small prototypes.

03

Instrument

Measure speed, repeatability, current draw, accuracy, cycle time, and repair effort.

04

Release

Freeze only what survives review, then preserve the result in drawings, code, and documentation.
