  1. Flexible propulsion mechanism
    Designed with applications for aerial and underwater drones in mind, this provides a noiseless and safe propulsion method without the need for propellers. It supports hybrid operation with fixed and movable wings, aiming for energy efficiency and environmental harmony.
  2. Miniaturizable actuator and motor structure
    Developed as the driving unit for the propulsion mechanism mentioned above, it is quiet, vibration-free, and produces strong torque. Two types were devised: one with a flat design and another incorporating a rotational axis.
