Introduction
The paper is the evolution from the authors' previous studies \cite{8404902,8967949,9561531}. We have developed several self-healing modules oriented for high-load applications such as legged robots. The module used low melting point alloy (LMPA), and the modules achieved transmission large initial tension and executed the self-healing sequence automatically. However, the modules have been suffered from the drop of the healed strength after the self-healing sequence. This study solves the problem by exploiting the robot's own actuator. Motor-driven tendon's vibration makes the liquid metal sloshing behavior which devastates the surface oxide on the fracture surface of the LMPA component. We validated the approach by the benchtop experiment and the robot's active self-healing behavior. We exploit the liquid metal sloshing caused by the robot’s actuator to enhance the healed strength up to tens of kilograms. The research provides another approach, the robot’s own motion, to self-healing robotics which has been improved bythe evolution of the materials, the composites, and the structures.
