A measurement system and a method of measuring an object is provided. The system includes a measurement platform having a planar surface. At least two optical sensors are coupled to the measurement platform that emit light in a plane and determines a distance to an object based on a reflection of the light. A linear rail is coupled to the measurement platform. A cooperative robot is coupled to move along the linear rail. A 3D measuring system is coupled to the end of the robot. A controller coupled to the at least two optical sensors, the robot, and the 3D measuring system, the controller changing the speed of the robot and the 3D measuring system to less than a threshold in response to a distance measured by at least one of the at least two optical sensors to a human operator being less than a first distance threshold.
