Publication number: 20180111271Abstract: A mechanical arm positioning method configured to position a mechanical arm at a fixed point. The method includes capturing a positioning pattern through an image-capturing module disposed on mechanical arm to generate an image with a positioning image, the positioning image corresponding to positioning pattern. Subsequently, whether a center of positioning image is located at a center of the image is determined. If not, a position of mechanical arm is adjusted in parallel with a plane where the positioning pattern is located until the center of positioning image is located at the center of the image. Subsequently, whether an area of positioning image is substantially equal to a predetermined area is determined. If not, a distance between mechanical arm and positioning pattern is adjusted perpendicular to plane where the positioning pattern is located until the area of positioning image is substantially equal to predetermined area.Type: ApplicationFiled: July 10, 2017Publication date: April 26, 2018Inventors: Hsiang-Tin HWANG, Jen-Hui WANG, Chiung-Hung WANG, Jen-Wei CHENG
