Throwing is an effective means of delivering robots to locations that are difficult for humans to approach directly. For more efficient monitoring, it is sometimes desirable for a thrown robot to remain attached to a wall without bouncing back when it collides with it.The goal of this research is to develop a robot that can attach to rock and concrete walls using adhesive resin and metal claws. In this paper, the claw parts made of soft and hard materials based on the design principle of Asbeck[5] were repeatedly attached to rocks, and the adhesive force was measured and evaluated. As a result, the 6 claws were able to generate more than 1.5[N] of adhesive force with 88% probability.
