Productive Robotics OB7 Stretch Overview
The Productive Robotics OB7 Stretch is a 7-axis collaborative robot that carries 4 kg over a 1250 mm reach. It is a longer-reach version of the standard OB7 and is widely used for tending lathes. At 22 kg the arm is light enough for cart or pedestal mounting on a 220 mm flange, and it repeats to ±0.1 mm. Programming is done by demonstration from a tablet, with EtherNet/IP, TCP/IP and Modbus available for machine communication.
