Abstract
The subject invention includes a coupling device for coupling a tooling arm to a robotic arm assembly. The coupling device includes a sensing mechanism which monitors relative distances within the coupling device in order to detect displacement in the coupling device. The coupling device also includes an adjustment method for setting the level of force required to execute a breakaway between the items being coupled, while providing a minimum magnetic holding force great enough to assure that robotic arm accelerations and de-accelerations can not cause the inertia or momentum to dislodge the tooling arm from the robotic arm assembly.
