Profile: American Robot Corp. produces specialized controls and machinery for the military & aerospace markets. We provide engineering, products, and services from concept stage through R&D, field trials, deployment & ongoing technical support. We manufacture industrial robot controllers, industrial robots, and automation systems. We offer two industrial robot product lines, Merlin six axis articulated robots, and the modular Gantry 3000 gantry style robots. Both product lines have various models and configurations. We also have two lines of open architecture industrial robot controllers, AARM motion controller, the universal motion controller, and the motion cube controller. MasterCal™ is a high accuracy, portable solution for mastering and calibration of industrial robots from any manufacturer. The MasterCal™ system is comprised of a touch probe, a ball bar and PC based software, with an easy to use graphical interface, & sophisticated, patented mathematics for high precision calculations. MasterCal™ allows the robot to be quickly and precisely aligned to the original factory specifications in minutes. MasterCal eliminates cumbersome mastering fixtures, and makes robot-to-robot variations & point touch up a thing of the past. MasterCal is based on a patented software algorithm which can fully determine the mechanical parameters of a robot arm, by reading the robot's position as it touches the surface of a sphere with a contact sensitive tool. Two such spheres are required, mounted on a ball bar, which can be placed at any location in the work envelope.
