Abstract: A parallel robot is composed of two kinematic chains connecting a base to a platform having two degrees of freedom so that the platform is movable with respect to the base in a plane (x, z) of a space (x, y, z) in which the directions x, y and z are orthogonal to one another. The kinematic chains each having a bend connecting a proximal sub-chain, itself connected to the base, and a distal sub-chain, itself connected to the platform. The proximal sub-chain drives the bend in translation in the plane (x, z). The distal sub-chain of at least one of the two kinematic chains includes two rods separated from each other in the direction (y). The first and second ends of each rod are connected to the bend and the platform, respectively, by respective systems of connections composed of two pivots with axes orthogonal to each other.

Abstract: The disclosure concerns a robot of the type including a base element and a mobile element coupled to the base element through an element for triggering movement. The movement-triggering element includes first and second subassemblies. The first assembly is designed to move the mobile element along a substantially vertical direction. The second subassembly connects the first subassembly to the mobile element and includes at least three actuators capable of acting in parallel to move the mobile element in a substantially horizontal plane independently of the first subassembly.
