Comau and Fincantieri collaborated on the MR4Weld mobile robot, which will be subsequently used within Fincantieri shipyards to autonomously weld steel structures. The robot features a high-payload, 6-axis articulated robot fitted with a welding torch that is installed on a tracked undercarriage and equipped with an integrated vision system to autonomously identify welding joints. Designed to be able to move in any environment and to collaborate with workers, the system can be managed by a single operator during transfer and welding activities. The system employs digital tools to collect welding and production data that can be used to record the welded joints.
