Spooky Jobs

Abstract

The Coral Crusaders, a high school team from Redmond, Washington, designed and built Spooky Jobs, a remotely operated vehicle (ROV) that earned 2nd place at the Pacific Northwest Regional MATE ROV Competition and 22nd place at the World Championships.

Built over 850 hours by a five-member student team, Spooky Jobs combined precision engineering with a passion for ocean conservation. The ROV featured six Blue Robotics T200 thrusters for five degrees of freedom, two waterproof IP cameras for adjustable views, and a pneumatic claw for underwater tasks such as coral transplantation and debris retrieval. Its custom-machined ABS frame, buoyant foam, and non-toxic bismuth and steel ballast ensured stability and control. Safety was a top priority, with 3D-printed thruster guards, a humidity sensor for automatic shutdowns, and smooth, sanded frame edges.

With a thoughtful blend of innovation, teamwork, and environmental purpose, the Coral Crusaders created a robot that not only performed beautifully underwater but also reflected their mission to protect marine ecosystems.
