ABSTRACT:
Self-propelled vehicle with articulated arms able to move in a tube or in a laminar space defined between two approximately parallel surfaces. It comprises a body equipped with at least one driving and guide wheel which bears on a surface on which the vehicle moves and at least two pivoting arms articulated on the body and terminated by bearing members which slide or roll on a surface facing and opposite to the first surface. It also comprises a device which transmits a pivoting torque to the arms in such a way that said arms bear on said opposite surface and by reaction apply the driving wheel against the first surface. A particular application is to the inspection of pipes within a nuclear installation in a radioactive atmosphere.
