Abstract
This paper describes insect-inspired flapping robots and measurement of dynamic lift force. Two types of robots based on dragonfly and butterfly were developed. The dragonfly-based robot imitates the take-off motion of dragonflies. The butterfly-based robot claps its wings and wags its abdomen synchronized with the flapping motion. In addition, a dynamic force measuring equipment was developed to measure the time-varying lift force of the robots. FFT was used for noise reduction of the data.
