Examining a boat’s outer shell is a necessary security measure before the entrance of any vessel into the harbor. Today, this dangerous job is performed by divers. Under the professional guidance of the Center for Robotics at Ben-Gurion University of the Negev, I developed a remote-control robotic unit for this purpose. The robot’s body contains the motors, an ultrasound scanner, and a camera. The motors operate two rubber wheels implanted with powerful magnets. The magnets attract the robot to the metal shell of the vessel. The method with which I incorporated the magnets into the rubber wheels allows the wheels to turn and the robot to advance alongside the shell of the vessel without disengaging from it. I designed the wheels with the organic character of underwater plants, thus improving their navigability and grip. The body is hydrodynamic, while the stabilizing tail, which also grips, gives it the silhouette of a fish. The result is a horizontally-symmetrical underwater robot. In my project I explored a new area that has no formal language of yet, and therefore everything created in it is new and unique. The model’s body is made with STL technology, and it is designed using ABS vacuum forming. Installed on the body are two electric gear-motors, which are controlled from a remote-control station through a robotic motor control card. The wheels were designed from rubber as a flexible support (TWheel) and the magnets were implanted at the molding stage. ![]() ![]() |
