Abstract
We have proposed an active hose to explore the narrow and complex space. The hose has the following two characteristics. One is that top of the hose grows by air pressure from within, and the grown part of the hose becomes hard and guide hose. The other is that the diameter of the hose can be changed according to the number of tube units. In this paper, the method that enables the hose to bend is described using heat shrinkable tube newly. This mechanism is confirmed by experiments.
