Abstract
Robots for inspection that can access to narrow spaces and are able to work in hazardous areas usually tend to utilize a large amount of actuators, and usually it is necessary to increase the thickness of the robot to make it longer. In this paper a new inspection system is proposed, which has a length of 40 meters with a constant diameter smaller than 20 millimeters and is actuated by three high pressure washing machines, through the variation of the pressure generated on each one. Experiments were carried out inside the water, on the ground and in a PVC tube to verify its mobility. First results are promising and confirm the applicability of the system for inspection tasks.
