The system is for detecting the position of a manually positionable torque tool 14 in relation to e.g. fasteners 8a-8d of a work piece 2. The tool 14 includes a head 15 for engagement with a rotary fastening and a light source 18 mounted on the head for indicating the position of the head to a remote position detection system. The intensity of light emitted by the light source may be varied in a pattern such as a series of pulses. The light source may be infra-red. A system and method for detecting the position of a torque tool includes a camera 10 arranged to view a work area 4 and being sensitive to light emitted by a light source on the tool. A memory stores a set of locations within the field of view of the camera, the locations corresponding to a set of operating positions in the work area. Also included is a means 12 for generating a coincidence signal when the sensed location of the light source on the tool coincides with one of the stored locations. |
