Mobile parallel robot machine for heavy-duty double-walled vacuum vessel assembly

Purpose This paper aims to present a detailed mechanical design of seven-degrees-of-freedom mobile parallel robot for the tungsten inert gas (TIG) welding and machining processes in fusion reactor. Detailed is presented both kinematic dynamic behaviors are studied. Design/methodology/approach First, model was created computer-aided (CAD) software, then simulation optimization were completed meet requirements. Then manufactured assembled. Finally, tests performed validation. Findings Currently, implementation system has been successfully carried out laboratory. The excellent performance indicated that robot’s software designs suitable given tasks. quality accuracy reached Originality/value industrial particularly used Furthermore, structure can be optimized different applications.
