Abstract
A robot teaching machine according to the present invention includes a guiding tool having a first angle sensor, a coordinate detector having a plurality of rotating portions and a second angle sensor for detecting a rotational angle of each of the rotating portions, a first motion transfer member for detecting a distance between the guiding tool and the coordinate detector that are connected with each other, a second motion transfer member for connecting the guiding tool and the coordinate detector and detecting an attitude of the guiding tool, and a coordinate converter for deriving a three-dimensional position and an attitude of the guiding tool from values detected by the first and the second angle sensors, respectively. The first motion transfer member and the second motion transfer member independently work for providing precise guiding data.
