Research on Key Techniques of Insect Flapping Onset Control Based on Electrical Stimulation

Area of Science:

• * Entomology
• * Bio-inspired robotics
• * Biomechanics

Background:

• * Insect flight control is complex and challenging to replicate.
• * Electrical stimulation offers a potential method for direct control of insect locomotion.
• * Understanding insect muscle function is key to developing bio-hybrid systems.

Purpose of the Study:

• * To propose and verify an insect flapping onset control method using electrical muscle stimulation.
• * To analyze the control principles of insect flapping onset via electrical stimulation.
• * To design and implement a wireless micro-control system for insect movement.

Main Methods:

• * Electrical stimulation of dorsal longitudinal muscles in beetles (Allomyrina dithotomus).
• * Design of a wireless micro-control system (PC controller, coordinator, electronic backpack).
• * Verification and comparative experiments to determine optimal stimulation parameters.

Main Results:

• * Controlled beetle flapping onset achieved with an average response time of 1.69 seconds.
• * Optimal stimulation parameters identified: 5 ms period, 40% duty ratio, 100 pulses, and 3.3 V amplitude.
• * Electrical stimulation effectively controls insect flapping onset behavior.

Conclusions:

• * Electrical stimulation of specific insect muscles is a viable method for controlling flapping onset.
• * A wireless micro-control system enables effective remote manipulation of insect movement.
• * Optimized stimulation parameters significantly improve control accuracy and response time.
