<p>CMM (coordinate measurement) functions are incorporated into robotic devices used a construction site system. The construction site system is capable of determining the absolute position of any physical point in three- dimensional space upon which the moving robot is to operate, that position is determined globally relative to monuments with known positions. A CMM determines the position of a point in three-dimensional space locally relative to itself. Combining the CMM functions with the global position determination functions improves the accuracy and precision of point location. The device disclosed in the Present Application comprises a motorized robotic arm having a plurality of moveable joints that give the arm the ability to reach out and touch any point in three-dimensional space within its reach. Attached to the robotic arm is a probe with a stylus having a sensor that will measure the coordinates of the point relative to itself. Coordinate information is then transmitted wirelessly to a control station. The device also transmits its absolute position wirelessly to a control station. Several different devices may be attached to the stylus. Coordinate measurement is only one function that can be performed. One device of significance would be an electronic distance measurement unit. This would enable the robot arm to be used either as a laser pointer and a distance measurement unit or as a total station. The arm can also be detected and seen by other robots and monuments on the site, and these other devices transmit the position of the Present Invention to the control station. The device has a locator device (such as a passive corner cube prism or an active wireless beacon) that can be seen by the other devices at the site.</p> |
