Abstract
The invention relates to an adaptive control tool holder for fixing to the end of the carrier of a robot, controlling the displacement of said end in accordance with a stored path. The tool holder defines a degree of freedom about an axis and a degree of translational freedom in a direction orthogonal to said axis. For a central translation reference position, the axis passes through the active center of the tool. A detection system rigidly fixed to the tool has preferably two detectors used for controlling the motors which control the two degrees of freedom, by means of independent feedback or control circuits. During the learning of the path prior to performing the task, the translation and the rotation are blocked in the reference position.
