Cobot Offers Longer Reach


The fourth model of the next-generation teachable collaborative robots (cobots), OB7-Stretch offers a longer reach to handle parts and machines with longer distances. OB7-Stretch is similar to the standard OB7 5kg model, but longer with a reach of 1.25 m and a slightly lower payload of 4kg.


Applications that will benefit greatly from OB-Stretch are those that require a longer reach to pick up a part or reaching deeper into machines. Specifically, applications in plastics molding, packaging, and palletizing will benefit greatly. 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.


The three other cobot models include standard OB7 (5kg payload and 1-m reach), OB7-Max 12 (12kg and 1.3-m reach), and OB7-Max 8 (8kg payload and 1.7-m 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-deg. in both directions allowing the cobot to work in more confined workspaces and areas that a six-axis robot can’t reach.
