Industrial robot body that performs linear motion along orthogonal coordinate system (X-Y-Z axes). Features gantry-type, portal-type, and desktop-type structures, achieving high-precision positioning and large working range. Optimal for parts handling, assembly work, inspection processes, palletizing, and pick & place operations. Unlike articulated robots, each axis has independent linear motion mechanism, enabling easy programming and high repeatability. Cartesian robot body realizes high-speed, high-precision operation through drive system combining linear guides, ball screws, and servo motors.
