ABSTRACT:
A robot-laser system having a minimum number of mirrors for reflecting a laser beam from a fixed laser beam source to a desired location wherein the mirrors are mounted within the hollow, servo-controlled parts of the robot to move therewith. Only a single mirror is mounted within its associated controlled part to reflect the laser beam as it travels between adjacent controlled parts. The robot has a number of degrees of freedom constituted by two orthogonally related linear movements along intersecting longitudinal axes and two orthogonally related rotary joints having intersecting pivotal axes. Preferably, two of the mirrors are mounted so that the laser beam strikes and is reflected from both points of axes intersection within two of the controlled parts. In one of the disclosed embodiments a mirror mounted in the base of the robot reflects the laser beam from the source to the other mirrors.
