Assembling Automotive Belt Tensioners with Promess REMAP Challenge: Producing automotive belt tensioners requires an assembly system that can monitor and control both linear and rotational motions in real-time to achieve the proper assembly sequence. The tensioner consists of a spring inside a housing which must be wound either to a specified location or to a specified torque. Once the spring is positioned inside the housing the linear actuator presses everything together with a controlled force that is light enough to allow the spring to turn while still being sufficient to hold the assembly together. At that point, the rotary axis is actuated to wind the spring to the specified position or torque, depending on the model being assembled. Control is then returned to the linear ax
