Field: Handling (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 17:
18. The method of claim 17,, wherein the AMR further comprises a broadband light emitter and a narrowband light sensor;, wherein the coupling structure further comprises a reflector;, wherein the method further comprises the steps of:
(a) emitting light from the broadband light emitter onto the reflector of the coupling structure;
(b) selectively reflecting the emitted light at a specific narrowband wavelength with the reflector; wherein the narrowband wavelength corresponds with an orientation of the AMR relative to the wheeled cart;
(c) recording the selectively reflected light with the narrowband light sensor;
(d) determining an orientation of the AMR relative to the wheeled cart based on the recorded narrowband wavelength;
(e) determining, from said AMR orientation, an orientation correction factor for adjusting an orientation of the AMR which includes adjusting a movement of the robot body or a rotation of the cart coupling system, or a combination thereof;, wherein the steps of (a)-(e) are performed prior to steps (i)-(ii).
