More Information
Summary:A system for applying material to a part includes an application nozzle attached to a distal end of a robotic arm, a sensor coupled to the distal end of the robotic arm, an actuator mechanically coupled to the application nozzle, and a controller in communication with the actuator and configured to receive data from the sensor and detect a feature of the substrate. The robotic arm is configured to hold the application nozzle in a fixed position and/or traverse a predefined path such that the application nozzle traverses a predefined global bead path across and spaced apart from a substrate. The controller is configured to direct the actuator to move the application nozzle independent of the distal end of the robotic arm such that a bead of material flowing out of the application nozzle is applied to the substrate along a feature-relative bead path.
