Overview
Based on the inverse piezoelectric effect of piezoelectric ceramics, a tripod crawling robot with variable cross-section bending beam support is designed. Through dynamic analysis and experimental verification, the effects of driving frequency, bending angle, load, and voltage waveform on motion direction and speed are studied, achieving left/right turning and approximately linear motion. This research serves as a reference for miniature crawling robot design and experimentation. ---
System Architecture
Signal flow summary: 1. **Controller** outputs signal to the high-voltage power amplifier. 2. **High-voltage amplifier (Ante ATA 300)** drives the piezoelectric tripod robot to produce motion in the specified direction. 3. **Panasonic laser displacement sensor** measures the displacement of the robot along the track and feeds back to the controller.
