Soft robots, made of elastomers and gels tend to easily break, punctured, or torn by contact with sharp and thin objects. To deal with this problem, we had proposed a robotic blood vessel mechanism that has a self-healing function by inserting liquid-filled blood vessels in the body. their bodies themselves. The liquid flows out and is cured which makes the would heal when the body breaks. In this research, we have improved the healing performance by attaching a liquid-absorbent material on the robot surface. Through experiment, it has confirmed that the self-healing ability can be improved by attaching the absorbent material.
