This paper studies the process in which soldier crabs cause group behavior. And, we focus on interaction between "robot" and "crabs' group". On the experimental, this paper considers three cases. First case, there are only soldier crabs(16) in the field. In the second case, there are the stationary robot and soldier crabs in the field. On last case, we use the moving robot in the same situation. These experimental results are analyzed by two schemes as follow. (1) We count directions where one crab advanced any four patterns(approach, leave, wall, the others). (2) We assume crabs moving same time to be same group, and count those of number. From the analyses, soldier crabs have the tendency to approach other crabs. Moreover we got knowledge that the motion of the robot activate soldier crabs' group behavior.
