Our Robot

Meet Sir. Swims-A-Lot

Sir. Swims-A-Lot is a Blue Robotics BlueROV2 Heavy Configuration converted from an ROV into an autonomous underwater vehicle. For 2026, the team is combining BlueOS, a Raspberry Pi 4, Navigator board access, and new MAVLink work to make movement and navigation more repeatable.

Vehicle Architecture

How The AUV Is Controlled

Platform

BlueROV2 Heavy Configuration

The smaller footprint and motor layout give the team confidence in movement-heavy tasks, especially roll attempts that the robot has achieved in past seasons.

Software

Navigator + MAVLink

The codebase has used the Blue Robotics Navigator Python library and is now integrating ArduSub MAVLink to broaden how the team can command and monitor the robot.

Sensing

Compass-Guided Stability

Compass data is central to the 2026 plan: maintaining heading, reducing drift, and supporting navigation tasks such as slalom and surfacing in the octagon.

Competition Strategy

Primary Missions First

Coin Flip

A primary goal that should be achievable with the existing codebase. The team is not prioritizing the restore and recovery role options.

Roll

The BlueROV2 size and motor configuration make roll attempts a good scoring opportunity, so the team plans to attempt it every run.

Gate, Slalom, Octagon

Gate uses reliable open-loop movement. Slalom and octagon surfacing lean on color detection, compass headings, and stable movement.

Return Home

A stretch goal attempted after higher-priority goals are working, aided by heading hold and improved stability.

Testing Strategy

Movement Consistency Over Flash

Hover Tuning

Motor speeds and balance are being adjusted so stable hover becomes less dependent on manual inputs.

Compass Heading

Reliable heading data is a major testing target because it supports navigation, stability, and octagon surfacing.

Connection Paths

The team has used Fathom X tethering and Wi-Fi router connections while learning what works best for testing and debugging.

2026 Season Outlook

The team is prioritizing movement-based challenges, heading stability, and code practices that make Sir. Swims-A-Lot easier to operate, understand, and improve year after year.
