Fishing line artificial muscles are fabricated by twisting nylon threads into a coil shape. Due to thermal contraction properties of nylon threads, they contract reversibly in response to temperature change. By using conductive nylon threads or by wrapping electric heating wire, the fishing line artificial muscles can be activated by electrical heating. However, local overheating often leads to breaking. Additionally, without a cooling mechanism, there will be a difference in the response speed of expansion and contraction. In this paper, we aim to realize a heating and cooling system with fluid to prevent breakage and improve response. For this purpose, a prototype of a tube integrated with fishing line artificial muscle is constructed and its response characteristics are verified.
