摘要:

六足机器人在黏土环境下行走时常发生沉陷且脱困受阻,对其行走稳定性及能耗等方面均产生了负面影响。考虑黏土的黏附特性及抗剪特性,建立了六足机器人在发生沉陷时的抬腿阻滞力学模型,揭示了足端沉陷量与抬腿阻滞力之间的相关性。设计并搭建了足地力学实验平台,基于该平台进行了六足机器人在3种步态下的足地力学实验,获得沉陷量与阻滞力数据,并与理论模型计算结果对比,验证了力学模型的准确性。采用EDEM软件模拟黏土环境,进行足地接触仿真,揭示了黏土内部力学行为变化规律。对比仿真结果、力学模型预测结果和实验结果发现数据变化趋势基本一致。

Abstract:

Hexapod robots often sinked and got stuck when walking in clay environment, which had a negative impact on the walking stability and energy consumption. The adhesion and shear resistance properties of clay were considered. A mechanics model of leg lifting block for a hexapod robot during foot sinking was established. The correlation between foot subsidence and leg lifting resistance was revealed, and the foot-ground mechanics experimental platform was designed and constructed. Based on this platform, foot-ground mechanics experiments were conducted on hexapod robots under three gaits. Data on sinking and blocking forces were obtained. The accuracy of the mechanics model was verified by comparing with the calculated results of theoretical model. Finally, EDEM software was used to simulate the clay environment and perform foot-ground contact simulations. The variation law of the internal mechanics behavior of clay was revealed. The comparisons of the results from simulation, mechanics model prediction and experiments show that the data change trends are basically the same.

Key words: hexapod robot, clay environment, foot-ground contact mechanics model, foot-ground mechanics experiment
