The SeaPerch underwater robotic is a well-liked instructional device for college students in grades 5 to 12. Constructing and piloting SeaPerch, a remotely operated car (ROV), includes a wide range of hand fabrication processes, electronics strategies, and STEM ideas. Via the SeaPerch program, educators and college students discover buildings, electronics, and underwater dynamics.
“SeaPerch has had an amazing affect on the fields of ocean science and engineering,” says Andrew Bennett ’85, PhD ’97, MIT SeaGrant schooling administrator and senior lecturer within the Division of Mechanical Engineering (MechE).
The unique SeaPerch undertaking was launched by MIT Sea Grant in 2003. Within the many years that adopted, it rapidly unfold throughout the nation and abroad, making a vibrant neighborhood of builders. Now underneath the management of RoboNation, SeaPerch continues to thrive with competitions around the globe. These competitions introduce difficult real-world issues to foster inventive options. Some latest matters have included deep sea mining and gathering information on hydrothermal vents.

SeaPerch II, which has been in improvement at MIT Sea Grant since 2021, builds on the unique program by including robotics and components of marine and local weather science. It stays a “do-it-yourself” maker undertaking with aims which might be achievable by center and highschool college students. Bennett says he hopes SeaPerch II will allow a good larger affect by offering an approachable path to studying extra about sensors, robotics, local weather science, and extra.
“What I feel is most precious about it’s that it makes use of ironmongery store elements that should be reduce, waterproofed, linked, soldered, or by some means processed earlier than turning into a part of the robotic or controller,” says Diane Brancazio ME ’90, Okay-12 maker workforce chief for the MIT Edgerton Heart, who co-leads the MIT SeaPerch initiative with Bennett. “[It’s] sort of like making a cake from scratch, as a substitute of from a mixture — you see what goes into the ultimate product and the way it all comes collectively.”
SeaPerch II is a household of modules that enable college students and educators to create instructional adventures tailor-made to their explicit desires or necessities. Choices embody a stress and temperature sensing module that can be utilized by itself; an autonomy module that the scholars can use to assemble a closed-loop computerized depth management system for his or her SeaPerch; and a lesson module for tender robotic “fingers” that may be configured into grippers, distance sensors, and bump sensors.
The fundamental SeaPerch is a PVC pipe construction with three motors and a tether to a swap field. Via the constructing course of, college students find out about buoyancy, structural design, hand fabrication, and electrical circuits. SeaPerch II leverages applied sciences which might be extra superior, cheaper, and extra accessible than they have been when SeaPerch was first conceived. Bennett says SeaPerch II is supposed to increase the unique SeaPerch program with out invalidating any of the present system.
Teagan Sullivan, a third-year scholar in mechanical engineering, first turned concerned with the undertaking in January 2023 by an Undergraduate Analysis Alternatives Program undertaking with MIT Sea Grant. Initially, she continued improvement of the tender robotics portion of the undertaking, earlier than switching to a extra basic focus the place she labored on body design for SeaPerch II, ensuring elements might match and that stability may very well be maintained. Later she helped run outreach packages, taking suggestions from the scholars she labored with to assist modify designs and make them “extra strong and kid-friendly.”
“I’ve been in a position to see the affect of SeaPerch II on a small scale by working immediately with college students,” Sullivan says. “I’ve seen the way it encourages creativity, and the way it has taught children that collaboration is the very best street to success. SeaPerch II teaches the fundamentals of electronics, coding, and manufacturing, however its finest power is the flexibility to problem the way in which folks suppose and encourage important pondering.”
The workforce’s imaginative and prescient is to create alternatives for younger folks to interact in genuine science investigations and engineering challenges, growing a ardour for engineering, science, and the aquatic surroundings. MIT Sea Grant is continuous to develop new SeaPerch II modules, together with incorporating land-water communication, salinity and dissolved oxygen sensors, and fluorometers.
Sullivan says she hopes this system will attain extra college students and encourage them to take an curiosity in engineering whereas educating the talents they should be the subsequent technology of problem-solvers. Brancazio says she hopes this undertaking evokes and prepares younger folks to work on local weather change points.
“Robots are supposed to assist folks do issues they couldn’t in any other case do,” Brancazio says. “SeaPerch is a robotic with a mission.”
