Six-Oar TrimaranMDA Press

Swimming Robot

November 22, 2024/by Prof. McCarthy

Jiaji Li has completed the design, fabrication and testing of his Oar-Driven Unmanned Surface Vehicle, better known as his Swimming Robot. The video below shows a rendering of the final design, testing of the coordination of the oars, which are driven in sets of three by two motors. And, finally, shows the robot swimming in […]

Oar-Driven Unmanned Surface Vehicle

Oar-Driven Unmanned Surface Vehicle

November 22, 2024/by Prof. McCarthy

This trimaran designed by Jiaji Li has three oars supported by spherical four-bar linkages on each side.  A motor on each side drives the set of three oars, and the relative speed of the motors steers the trimaran.  The result is a robot that swims.
