A structure with six degrees of freedom for a robot or haptic interface including a base, two branches in parallel, and a wrist joint. The branches are installed articulated between the base and the wrist joint, the branches including a shoulder, an arm, and a forearm supporting the wrist joint. The wrist joint includes a connecting segment onto which a handle holder is articulated about a first rotation axis. A handle is articulated in rotation on the handle holder about a second rotation axis, the handle capable of being moved in rotation about the first axis, the second axis, and a third axis, and a mechanism gears down the rotation of the handle holder about at least the first rotation axis relative to rotation of the connecting segment. |
