The RS3 Robot, from EPSON Robots, uses a unique work-space design that maximizes work envelope usage, in zero footprint.
The RS3 offers a 350mm SCARA arm featuring a working quadrangle greater
than that of a typical 750mm SCARA arm. Since there is no dead space in
the center of the work envelope, the RS3’s working quadrangle is
494mm x 494mm. With the ability to maneuver back under itself, the robot delivers
improved cycle rates. It is also capable of easy integration into
compact assembly cells. The RS3 provides over 360 degrees of axis
rotation for omni directional access.
