More power in smaller robots

System Devices, sole supplier of Seiko Epson robots in the UK, is introducing a novel series of small, high-speed mini Scara robots (see Plate 3). Junior of the EC family has a payload maximum of 3kg, a standard cycle time of less than half a second with a load of 1kg, and a choice of 250 or 350mm arm lengths. Precision for fast assembly applications is impressive: 0.01mm on first, second and third axes, and 0.03 degrees on the fourth axis. This is coupled with a speed of more than 2,500mm/second on a 2,500mm or 350mm arm, 1,000mm/second up and down, and 2,368 degrees/second rotation.

Higher up the scale is the ES/EL series with arm lengths of 450, 550, 650 or 850mm, handling a payload up to 5kg, again in a standard cycle time of less than half a second. In both ES/EL and EC series, cleanroom versions are available.

Top of the Epson range is the powerful EH series, with 850mm arm length taking a payload up to 15kg, and with an extended Z stroke up to 620mm, supported by strong guide rods to prevent distortion and ensure high precision.
