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 a straight line movement, gentle turning, and movement to two separate locations.

This water surface robot is a remarkable demonstration of the capabilities of 3D printed spherical linkages.
