drawing felxible material (conduit)

Is there anyway to draw "flexible" conduit? I am trying to do a study motion for a dress package on the robot , but  because the conduit is a solid piece, locks  the nuckle of the robot which is located in between the start and the end point of the conduit. Is there anyway to make a "flexible" conduit this way it will expand/bend follow during the  robot moves . I'd really appreciate if there will be someone to help me out with this issue.

Thank you
