Many robotic applications require the use of a break- away or safety coupling to protect the end effector mounted to the robots tooling flange. Problems encountered with commercial couplings range from unacceptable size, poor positional repeatability, slow response time and poor electrical construction. This flexi- ble coupler was designed for robotic applications that require precision parallel mounting surfaces and exact- ing positional repeatability of the end effector. The cou- pler is a rigid structure that minimiies end effector over- all length, has a breakaway torque range of 50 in-lbs to 250 in-lbs, has sensitivity adjustment, and has the advan- tages of spring damping. The invention is a new and unique design that provides a combination of features that is not available in other couplers.
