Abstract:
1. A tool tip position detecting device for a remote controlled actuator, the remote controlled actuator including a spindle guide of an elongated shape, a main body housing connected with a base end of the spindle guide, a tool rotatably supported by a tip end of the spindle guide, a tool rotation drive source for rotating the tool through a drive transmission unit inserted within the spindle guide, and an operator unit for operating the tool rotation drive source, which device comprises: an external force free position detector for detecting a position and an attitude of the main body housing to detect a tip position of the tool when no external force is applied to the tool and the spindle guide, from a detection value thereof; a strain detector for detecting a strain of the spindle guide; and a corrector for correcting the tip position of the tool, detected by the external force free position detector, with the use of a detected strain value of the strain detector.
