A machine for aligning items in a pattern and a method of using the machine. The machine includes a robotic assembly having four spaced apart joints. The joints including a base joint which is mounted to a stationary surface and a wrist joint onto which an effector is secured. A suction cup is mounted on the effector and is connected to a vacuum source. The suction cup is capable to picking up, positioning and releasing a new item relative to a first laid item and a second laid item. The first and second laid items each have an upper surface and each is aligned perpendicular to one another. The machine further includes three edge sensors and three height sensor. At least one of the edge and height sensors are secured to a first side of the effector and is capable of detecting an edge aligned along an X-X axis of the first laid item and the height of the upper surface of the first laid item, and at least one of the edge and height sensors are secured to a second side of the effector and is capable of detecting an edge aligned along a Y-Y axis of the second laid item and the height of the upper surface of the second laid item. The machine further includes a control mechanism for operating the robotic assembly, the vacuum source and the edge and height sensors. Lastly, the machine includes a power source for supplying power to the control mechanism.
