  • Device and method for tracking the movement of a tool of a handling unit
    Patent number: 8199316
    Abstract: A description is given of a device (1) for tracking the movement of a tool of a handling unit (2), having at least one directional radiator (5) that can be aligned with the tool and be tracked, and a signal evaluation unit (4) for determining the movement. The directional radiators (5) have actuators for aligning the directional beam (6) at adjustable angles with reference to a fixed spatial plane, and angle sensors for determining the current directional beam angle with reference to the spatial plane, the angle sensors being connected to the signal evaluation unit (4). Directional beam sensors (7) for detecting the directional beam (6) are arranged with a fixed reference to the tool and movably therewith, the directional beam sensors (7) being connected to the signal evaluation unit (4).
