Mobile device for generating and moving a laser beam in a predetermined manner

A mobile device (1) for generating and moving a laser beam in a predetermined manner, characterized in that the device (1) comprises:

• a laser device (2) configured to generate a laser beam (3) and project it onto a surface (9;
• 19);
• a manipulator (4) connected to the laser device (2) and configured to move at least the laser device (2) so that a laser point (33) of the laser beam (3) generated by the laser device (2) can be moved around onto the surface (9) in a predetermined pattern (10);
• and
• a control unit (5) configured to provide instructions for the manipulator (4) to move around the laser device (2) and subsequently the laser point (33) of the laser beam (3) onto the surface (9) in the predetermined pattern (10), characterized in that the manipulator (4) comprises:
• a housing (20);
• a laser motor (6) attached to the housing, wherein the laser motor (6) comprises a drive axle (61) onto which is fixed the laser device (2) and wherein the laser motor (6) is configured to rotate the drive axle (61) and subsequently the laser device (2) around the longitudinal axis (6X) of the laser motor (6), and wherein the laser device (2) is fixed onto the drive axle (61) so that the longitudinal axis (2X) of the laser device (2) is orthogonal to the longitudinal axis (6X) of the laser motor (6) and respectively drive axle (61);
• a mirror (7) rotationally attached to brackets (22) of the housing (20) so that the mirror (7) can rotate around its longitudinal axis (7X);
• a mirror motor (8) attached to the housing (20) and operationally connected to the mirror (7) by means of a gear transmission (21) so that a rotational movement of the mirror (7) can be provided by the rotation of the mirror motor (8);
• wherein the longitudinal axis (6X) of the laser motor (6), the longitudinal axis (7X) of the mirror (7) and the longitudinal axis (2X) of the laser (2) are orthogonal to each other, and wherein a rotation of the laser device (2) and mirror (7) coordinated by the control unit (5) ensures projection of the laser point (33) of the laser beam (3) in the predetermined pattern (10).
