  • Patent number: 11913590
    Abstract: A flexible peristaltic robot with a built-in bidirectional gas pump for self-regulating gas flow. The robot includes a head-end airbag, an extension-retraction airbag, a tail-end airbag, a power module, a control module and a bidirectional gas pump. When there is harmful gas or less gas in the external environment, an additional airbag is provided in the flexible peristaltic robot to form a closed internal circulation of air flow. Otherwise, the robot directly exchanges gas with the external environment to form an open external circulation of air flow. The flexible peristaltic robot can either use multiple bidirectional air pumps or use a single bidirectional air pump and multiple electrically-controlled switches to control the expansion and contraction of the airbags to enable the robot to move forward.
