Cyclo-UUV: Amphibious Cycloidal Propeller Unmanned Underwater Robot

This is the Cyclo-UUV: an amphibious cycloidal propeller underwater vehicle that uses cycloidal propellers, screw propellers, and tank treads to operate on land and under water. Its 4 propellers allow for underwater operation. They can be retracted into 4 wheels to transition from water to land locomotion.

This robot weighs 95lb. As the researchers explain:

Control of the vehicle underwater is achieved by modulating the cyclo-propeller rotational speed and blade pitch phase angle, allowing for control over the magnitude and direction of the thrust vector of each cyclo-propeller to enable surge, heave, roll, pitch, and yaw motions.
