Abstract

A tool tip position detecting device for a remote controlled actuator having an elongated spindle guide, a tool fitted to a tip thereof and a main body housing having a base end of the spindle guide connected thereto. The device includes an external force free position detector for detecting the tip position of the tool 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, which has been detected by the external force free position detector, with the use of a detected strain value of the strain detector.
