Charleston students race underwater robots—and need more space to build them

Every year, students in Charleston learn how to build robots that swim underwater. Their toolkit includes PVC pipes, wires, and small motors to craft gadgets that can navigate pools and race against other schools. The program started small but now has three times as many participants as it did a few years ago, turning the original storage closet into a crowded workshop. What began as an after-school activity has grown into a serious learning experience. Students don’t just glue PVC pieces together—they follow engineering steps similar to what scientists do in real underwater research. They sketch designs, test buoyancy, and troubleshoot when a robot sinks too fast or won’t steer straight. For many, it’s their first time using tools like drills and wire strippers, skills that aren’t always taught in regular classes. The demand has outgrown the available space. Tools sit on shelves instead of hanging neatly, and shared equipment like cutters and screwdrivers are always in short supply. Organizers want to install wall pegboards so students can see every tool at once, cutting down on time wasted searching for the right size drill bit. They also want to stock up on backup parts before the next competition season starts.Earlier this year, teams from Charleston traveled to an international event and came home with second place overall. They earned medals in categories like teamwork and technical design, proving the program works—but only because students put in extra hours outside of school. Most families can’t afford to buy extra PVC pipes or replacement motors on their own, so donations keep the club running. Back at school, the coach sees students who once struggled with math problems now calculating thrust and drag without thinking twice. Some have started talking about careers in robotics or marine biology, fields they barely knew existed before joining. The lessons aren’t just about building robots; they’re about solving problems, working in teams, and seeing mistakes as steps to improvement. Still, without better storage and supplies, the program risks running out of room—and fast. A single donation buys a set of pegboards or a new set of heavy-duty cutters, both of which could help dozens of students in the coming months. For every $50, one student gets a full season’s worth of tools.
