Design and Experiment of a Kinematic and Mechanical Test System for Excavation of Mole Crickets

Abstract

The high-efficiency excavation of mole cricket is associated to their motion pattern and the action mode of digging force. In this paper, we present a kinematic and mechanical test system for synchronously acquiring the excavation motion and digging force of mole crickets. This system can realize the synchronous acquisition of mechanical data and image data during the excavation of mole crickets. According to the excavation characteristics of the mole cricket, the structure of the mechanical test system was designed to realize the capturing of the digging force. Based on LabVIEW software, a host computer control interface of the software system was designed, which can realize the data acquisition, calibration and playback. A synchronous trigger module was designed to ensure the synchronism of high-speed image and digging force acquisition. The results show that proposed test system can synchronously obtain the kinematic and mechanical data of the excavation of mole crickets, and provide the equipment guarantee for further study.
