Patent attributes
A robot system includes: a robotic hand configured to load and unload a workpiece into and from a cassette in which a plurality of workpieces are aligned in a first direction; a sensor configured to detect the workpiece; a transporter configured to change a relative position of the sensor with respect to the cassette in the first direction and in a second direction; and circuitry configured to: control the transporter to arrange the sensor at a first position; command the sensor to scan in the first direction, to acquire first mapping data; control the transporter to arrange the sensor at a second position by changing the relative position of the sensor in the second direction; command the sensor to scan in the first direction, to acquire second mapping data; and determine that one or more of the workpieces are inclined based on the first and second mapping data.
