Abstract-Underwater robotics projects offer an excellent medium for discovery based engineering and science learning. The challenge of building underwater robotic vehicles and manipulators engages and stimulates students while encompassing a very broad spectrum of engineering disciplines and scientific concepts. This paper describes the successful design and implementation of student projects, building wire guided remotely operated underwater vehicles (ROVs) with motorized grabbers. This work is part of an ongoing effort to incorporate innovative, hands on projects into our freshman engineering curriculum. These projects help expose students to practical design issues in the freshman year, foster creative problem solving skills and may aid student retention on engineering programs. These projects have also been successfully piloted in pre-college programs, aimed at generating interest in engineering careers among high school students. We describe ongoing work to extend these projects to include computer control and sensory feedback, allowing students to develop autonomous underwater vehicles (AUVs). Further, we outline ongoing work to assess the effectiveness of these modules
