Epson RS-Series SCARA Robots

About the Epson Spider RS-Series SCARA Robots

The most unique and flexible SCARA robot in the market today, the Epson RS-Series SCARA Robots sets new standards in motion capability. With the ability to reach behind itself and cross back under, it fully utilises the workspace beneath the arm. This innovative design ensures there’s no lost space in the centre of the working envelope, making every inch count. Additionally, as a zero-footprint robot, it maximises efficiency without requiring extra floor space—ideal for compact production environments.
