Abstract: Self-contained apparatus able to move along a non-horizontal surface and comprising a first train and a second train (48) connected to the first train by devices allowing to obtain a relative displacement by translation and rotation in a plane parallel to the surface, and first and second holding devices (2) carried respectively by the first and the second trains and able to fix removably the apparatus on the surface, wherein the holding devices carried by at least one of the trains are connected to the train through devices capable of displacing said train with respect to the holding devices in a direction perpendicular to the surface. Preferably, the holding devices (2) of the first train are comprised of a plurality of adherence devices forming a polygon and arranged outside the center of the holding devices of the second train, and the apparatus further comprises a processing or inspection tool (60) mounted so as to pivot with respect to the first train.

Abstract: The invention relates to a device for maintaining on a non-horizontal surface an apparatus adapted to move along said surface.Said device consists, according to the invention, of a support (1) adapted to move normally to the surface carrying the apparatus, of a rocking lever (5) having a flexibility held within a certain range to allow it to accommodate changes in curvature, and of at least two suction cups mounted close to the ends of the rocking lever. There is thus afforded a more reliable, less expensive holding effect.

Abstract: A robot system is disclosed comprising a robot having a plurality of articulated members, actuator jacks for effecting movements (locomotion or other operations) of the articulated members, and a data processing unit controlling the jack actuators. One articulated member is pivotally mounted about three separate axes intersecting at a first fixed point. Two jack actuators are provided for the one articulated member. Two ball joints articulate the jack actuators to the one articulated member about two points separate from and out of alignment with the first fixed point and two other ball joints articulate the jack actuators about respective second and third points also separate from and out of alignment with the first fixed point. The one articulated member comprises a perpendicular plate, the two points articulated to the jack actuators being disposed at the plate and the axes of the two jack actuators lying in mutually perpendicular planes.
