CARPINTERIA, Calif. — Productive Robotics, Inc. introduces a fourth model of its next-generation teachable collaborative robots (cobots), OB7-Stretch.

OB7-Stretch is similar to the standard OB7 five-kilogram model, but longer with a reach of 1.25 meters and a slightly lower payload of four kilos.

“We have many customer’s applications that need a bit more reach, but have lighter payload needs. OB7-Stretch was designed for those applications,” said Zac Bogart, president of Productive Robotics.

Applications in plastics molding, packaging, and palletizing will benefit from the longer reach. In CNC machine tending, OB7-Stretch can tend multiple machines at one time when the robot needs to reach more than one machine, and when the robot needs to reach deeply into a machine.

While Productive Robotics has two larger models with longer reaches, OB7-Max 12 and OB7-Max 8, OB7-Stretch provides a cost-effective alternative to the higher payload and reach robots, priced the same as the standard OB7 model.

“We’ve had a lot of requests for a reasonably priced collaborative robot with a longer reach than is available on the market.  OB7-Stretch is that product,” states Zac Bogart.

OB7-Stretch is the fourth addition to the OB7 family. The three other cobot models include standard OB7 (5kg payload and 1 meter reach), OB7-Max 12 (12kg and 1.3 meter reach), and OB7-Max 8 (8kg payload and 1.7 meter reach). Each robot is built with seven-axis capabilities and “no programming”, simple, teaching platform – the user simply shows OB7 how to do the job and OB7 learns – providing customers with complete ease of use.

OB7 offers ultimate flexibility thanks to its seventh axis. Like a human arm, seven joints give OB7 the flexibility and dexterity to reach around objects or obstacles where others can’t. Unlike a human arm, each of OB7’s joints can rotate 360 degrees in both directions allowing the cobot to work in more confined workspaces and areas that a six-axis robot can’t reach.
