The 28ᵗʰ annual RoboSub competition will take place August 11–17, 2025 at the Woollett Aquatics Center in Irvine, California. RoboSub is an international student challenge in which interdisciplinary teams design, build, and demonstrate fully autonomous underwater vehicles (AUVs). Over the course of a week, each AUV must navigate a predefined mission course, completing a series of increasingly complex tasks—mimicking real-world subsea operations such as data collection, precision navigation, object manipulation, and environmental stewardship—to earn points and vie for top honors
Collecting Data (Gate)
Objective: Begin the run by navigating the AUV through an underwater “gate.”
Animal Selection: Upon passing the gate, the vehicle must select and “lock on” to either the Reef Shark or the Sawfish.
Orientation Bonus: For every 90° change in yaw, roll, or pitch (up to 720° total), teams earn extra points—rewarding vehicles that demonstrate precise attitude control from the very start.
Navigate the Channel (Slalom)
Objective: Perform a slalom maneuver through a field of alternating white and red vertical PVC pipes.
Scoring Tip: Higher scores are awarded for passing fully beneath the top plane of each pipe, underscoring the importance of depth control and smooth trajectory planning.
Ocean Cleanup (Octagon)
Objective: Use an acoustic pinger to locate the center of an octagonal zone on the pool floor.
Trash Sorting: Retrieve and sort trash items into two designated bins; points are given for correctly sorting at least two of each object type.
Rotation Bonus & Return: Vehicles can earn extra credit by rotating a number of 360° turns equal to the count of collected items, then surfacing back through the start gate to complete the run.
“RoboSub empowers the next generation of engineers to harness autonomous robotics for ocean conservation and innovation—challenging student teams to design AUVs that safeguard marine ecosystems, develop deep technical expertise, and foster lasting professional connections through a hands-on, mission-driven competition.”
