Abstract: Vehicle able to move by adhesion on a random surface, with a central body defining a pivoting axis which remains substantially perpendicular to a surface and which has two groups of central supports which adhere to the surface; first and second carriages, each provided with two groups of adhesive end supports; first and second members for the guidance in rectilinear translation and without rotation of the first and second carriages in accordance with two directions which remain substantially orthogonal to the pivoting axis. The first and second carriages are displaceable along the guidance members; the first and second guidance members are pivotal about the pivot axis and the groups of central supports are rotatable about the pivot axis.
