About Circuit Trees
Circuit Trees is Gibson Ek High School's RoboSub team from Issaquah, WA. After earning Rookie of the Year in 2024 and improving our robot and codebase through 2025, our 2026 season is focused on reliable autonomous movement, cleaner software practices, and passing technical knowledge to newer members.
Competition
Mission
The team uses autonomous underwater robotics as a full engineering cycle: design, build, test, document, compete, and teach the next group how the system works. The robot matters, but the real goal is students who can reason through hard technical problems.
Culture
Mentors coach through questions and review, while students own the work. That means competition strategy, software direction, mechanical changes, documentation, and troubleshooting stay in student hands.
2026 Technical Direction
Our strategy separates primary objectives from stretch objectives so the team can spend its time on the missions most likely to produce reliable points.
Coin flip, roll, slalom, gate, and surfacing in the octagon are the core 2026 targets. These emphasize controlled movement, headings, and repeatable autonomous behavior.
The team is upgrading software while making the codebase easier to understand, maintain, and pass down as new students join the program.
Return home and torpedo foundations are stretch areas. We only push them hard after the higher-priority autonomous goals are working consistently.

How The Team Works
Think, Sense, and Act tracks break the AUV into ownership zones: autonomy and mission logic, perception and sensor feedback, and the physical systems that make the robot move reliably.
Business members handle outreach, fundraising, documentation, and competition logistics so the technical groups can keep building without losing the support structure around them.
