A system for advancing an article along a path, comprising: a head member a dispatching member and an eversion sleeve configured with an inverted portion having a sleeve end configured to be fixed to the dispatching member, an everting portion configured for articulating to the head member and an un-inverted portion configured to extend from the everting portion towards the dispatching member, at least partially within the inverted portion said un-inverted portion and said inverted portion are configured to form a fluid receiving space therebetween for receiving a propelling fluid for exerting force on the everting portion, thereby gradually advancing a segment of the un-inverted non-inverted portion towards the head member, causing it to displace with respect to the head member, gradually advancing a respective segment of the everting portion into the inverted portion, thereby everting said eversion sleeve inside out and advancing the head member along the path wherein said head member is configured with one or more revolving elements configured for engaging said everting portion and for revolving upon displacement of the everting portion thereon with respect to the head member.
