Product Features

RR757 is a SCARA robot and all axes have stepping motors with absolute encoders.
The synchronous interpolation of the arm axis and rotation axis enables 2-port access without the X-axis track. The double arms exchange wafers in the shortest period of time to improve the transfer throughput.
The robot X-axis track can be added outside to perform the simultaneous control from the robot side including the teaching positions.

• Stepping servo motors with ABS encoders are mounted on all axes.
• 2-port access without X-axis track is available.
• Heavier hand can be equipped by increasing the arm rigidity.
• High throughput by double-arm specification.
• Control of the robot X-axis track is available.
