Robotic system and method for aligning a target (36) to an equipped vehicle (34) for calibration of a sensor (32) on the equipped vehicle (34) includes a vehicle support stand (42, 142, 242) upon the equipped vehicle (34) is disposed in an established known position for calibration of the sensor (32), and a robotic manipulator (38) having a multi-axis robotic arm (38a) configured to moveably hold a target (36). The robotic manipulator (38) is configured to position the target (36) into a calibration position relative to the sensor (32) on the vehicle (34) by longitudinal movement of the robotic manipulator (38) relative to the support stand (42, 142, 242) and by movement of the robotic arm (38a) based on the established known position of the vehicle (34) on the support stand (42, 142, 242) whereby the sensor is able to be calibrated using the target (36).
