This study focused on the difference of kinematics between mole crickets and normal insects in terrestrial walking. In order to study the function of the specialized foreleg, the adjustments made to the foreleg amputation were discussed by analyzing the motion ability, gait, and body posture of the mole cricket with and without forelegs. The re- suits show that mole crickets walk in terrestrial locomotion by using a special tripod gait, with the clumsy foreleg not as func- tional as normal hexapods. Mole cricket can make corresponding adjustments for the situation of missing forelegs, and achieve required molion stability with remained four legs.展开更多
