An Aerial–Aquatic Hitchhiking Robot with Remora‐Inspired Tactile Sensors and Thrust Vectoring Units
Advanced Intelligent Systems, EarlyView., 2023 An untethered aerial–aquatic hitchhiking robot that can be remotely controlled for flying, swimming, and transiting air–water boundaries rapidly (0.16 s), is presented. Notably, it can autonomously attach to various surfaces in both air and water environments using a remora‐inspired suction disc with flexible tactile sensors.

The use of active controls to augment rotor/fuselage stability [PDF]
, 1985 The use of active blade pitch control to increase helicopter rotor/body damping is studied. Control is introduced through a conventional nonrotating swashplate. State variable feedback of rotor and body states is used.
