The invention provides a system for handling pot lids in an aluminium production plant. The system comprises a robot assembly and a sensor system. The robot assembly comprises at least one manipulator arm and a lid gripper apparatus configured to grip at least one protruding or upstanding formation on a pot lid. The lid gripper apparatus is mounted at one end of the at least one manipulator arm. The sensor system is operable to generate position information to control the position of the at least one manipulator arm and/or lid gripper apparatus.

The invention provides an anode replacement system for electrolytic cells of an aluminum production plant, the system comprises a support frame and at least one movable member mounted on the support frame wherein the at least one movable member supports at least one anode gripping apparatus. Each of the at least one anode gripping apparatus is configured to grip a shaft of at least one anode assembly at any position along the shaft of the at least one anode assembly. The system comprises a sensor system configured to generate or collect position information to control the position of the at least one anode gripping apparatus.
