Abstract: A system for applying material to a substrate includes a nozzle, robot, actuator, sensor, and controller. The robot provides primary movement such that the nozzle traverses a predefined global bead path across and spaced apart from the substrate. The actuator provides secondary relative movement between the nozzle and substrate. The sensor senses a first location on the substrate that is spaced apart from a location where the nozzle deposits material by a distance based on a sensor response time and relative speed of the nozzle and substrate. The controller detects a feature of the substrate based on the data received from the sensor. The controller directs the actuator to provide the secondary relative movement such that a bead of material is applied to the substrate along a feature-relative bead path. The controller controls the actuator to provide the secondary relative movement based on the response time and the relative speed.
