A quadcopter that works in the air and underwater and also has a suction cup for hitching a ride on a host Robot transition and propeller speed vs. time during the transition. Images of the robot with self-folding propellers (A), commercial propellers (B), and fixed-unfolded propellers (C) taking off from the water at various time instants in a laboratory water tank. The average rotational speed and total transit time of the different propellers vary across propeller configurations. (D-F) The range between the two black dashed lines is the boundary transition period. Credit: Science Robotics (2022). DOI: 10.1126/scirobotics.abm6695
