The RR492/frog leg arm vacuum robot realizes the high positioning repeatability and highly reliable vacuum partition performance by adopting DDM (vacuum direct drive motor) for the drive section. The full-link arm mechanism realizes the highly accurate positioning repeatability.
High accuracy.
Available for ultrahigh vacuum.
High throughput.
Available for the AWC option (wafer position compensation).
