Kawasaki unveils four-legged robot that welds ship hulls

Kawasaki Heavy Industries showed a four-legged prototype measuring 60 by 44 by 29 cm that clings to steel ship hulls with electromagnets and welds seams. Demonstration testing is planned for 2027 at Sakaide Works in Kagawa, with practical use targeted around 2028.

• Robot measures 60 by 44 by 29 cm and grips hulls with electromagnets
• Cameras and sensors assess seams and decide how much welding is needed
• Testing at Sakaide Works in 2027, practical use around 2028
• Aims to offset a shortage of experienced shipyard welders
