The National Underwater Robotics Challenge is an underwater ROV competition that emphasizes real-world hands-on activities that motivate students to take on tough challenges in a fun and exciting way. Teams compete in one of four categories: Pre-High School, High School, University, and Adult. The goal of the various levels is to encourage vertical articulation, or collaboration and communication, between the levels to stimulate the teams to be the best they can be. Teams can choose from several levels of kits to build their ROV or build one on their own. The event is webcast live and takes place at night to simulate the dark depths of the ocean!
