Project Goal: Design and build an autonomous machine that can systematically torque large quantities of fasteners, and provide a user interface that allows the system to be programmed to operate a wide range of assembly configurations.

At Raytheon, installing fasteners is a manual process. A typical assembly has 90-200 fasteners, each needing to be sequentially torqued to a specific value and commonly requiring a team of operators two to six hours to complete. Existing automatic torque tools lack the required control and accuracy. Although robots are good at automating repetitive tasks, they run into trouble when the context of the application lacks consistency. A different type of robot could solve these key challenges.

In this design, the graphical user interface allows input and editing of assembly parameters, generates a pre-run simulation/graphic, provides troubleshooting capabilities, generates documentation and other advanced functions. A gantry system moves the custom-built torque appliance in the x, y and z directions. Cameras employ machine vision algorithms‚ allowing the system to localize and adjust to the fasteners’ true position in real time.

The modular design and robust control software provide a reliable autonomous torque system that can be scaled to larger and more complex applications.
