Flap like a bat: Soft pneumatic wings for biomimetic ornithopters
This paper describes the development of a bio-inspired ornithopter wing mechanism that uses soft pneumatic actuators, such as PneuNet structures, in place of revolute joints, inspired by the complicated kinematics of bat flight.
The authors present a proof-of-concept soft pneumatic wing mechanism for ornithopters, validated via ANSYS FEA simulations rather than full-scale flight tests; claims of reduced acoustic signatures and enhanced adaptability are based on design principles and preliminary demonstrations.

The proposed design employs pneumatically driven air pockets within a flexible wing skeleton to achieve smooth, lifelike flapping motion. The a

ctuation system is controlled by 3/2-way solenoid valves and an air pump, which manipulate airflow and actuator deformation. We demonstrate, using ANSYS FEA software, the bending behavior of the PneuNet actuators under varying pressures to inform the wing's structural design. The implementation of soft robotics in the flapping-wing system offers potential advantages over traditional mechanisms, such as reduced mechan
