RobotWorx Converting Old Robot Arms into Positioners

POSTED 04/19/2011

g class="" hspace="7" alt="Repurposed robot from RobotWorx" align="right" width="300" height="227" src="/userAssets/riaUploads/RoboxWorx_repurposedrobot.jpg" />Industrial robot integrator, RobotWorx, has found a new way to, “reduce, reuse, and recycle,” by repurposing robotic arms as servo positioners. This green solution allows the company to reuse more parts from older model industrial robots and provide customers with affordable workcell components. 

“We’ve had success thus far retrofitting nearly a dozen positioners from robots,” RobotWorx President Jarrod Bichon said. “It benefits customers because the recycled positioners are half the cost of normal servo positioners and they provide the same performance capabilities.” 

Such retrofitting is only possible with older robot arms. New robot models typically have a second axis that is cast as a single piece, while many older robot models (particularly the Motoman SK120 and FANUC S430) are constructed in segments so that the top of the robot can be easily removed. The remaining robot base is cleaned, tested, and outfitted with a tabletop before being integrated with the robot controller. 

Servo positioner tables serve an important purpose inrobotic workcells. They are designed to bring parts within the robot’s work envelope. Not only do positioners play an important role in the working of a robotic cell, they also factor into the final price tag too. However, RobotWorx’ retrofitted servo positioners present a much more affordable option for those in the market for a robotic workcell. Positioners fashioned in part from older robot bases cost 50% less than new. 

The older robots chosen for servo positioner retrofitting are often models that have seen better days. Many have been overloaded with tooling, especially spot welding guns, that caused the center of mass to be located too far for the robot to handle. Other models have not received appropriate preventive maintenance. Turning such abused robots into servo positioners extends their usability. RobotWorx inventories all remaining robot parts from the upper half of the arm.
