Epson SCARA G3-251S

It's all in the curve
A SCARA robot that takes up little space, but offers great reach and versatility.
G3-Series SCARA robots are the right choice for use in confined spaces, as despite their small size, they have a substantial work envelope. Because many assembly tasks can only be performed in one arm orientation, we've developed the Epson G3 series with an arm that is curved to the left or right. This unique arm geometry allows maximum square working area to be increased by up to 40 percent.
