Objective:
The project developed a collars, clips and erection joint application robot (CCE-A Robot). This robot was an extension of RTTās work on the development of the High Mobility Manufacturing Robot (HMMR) prototypes. The CCE-A Robot completed welds in difficult to access areas and enclosed spaces during ship assembly, erection and post-erection periods of construction. No temporary tracks were required and the CCE-A Robot did not need bolting to the deck plate.
Summary:
Robotic welding cells trace their origins to the 1960ās. The robotic welding arms used then and those used now in US shipyards have not changed much in size and weight. This has historically limited welding robots to materials that can be brought to where the welding cells are located. Today, small, lightweight robotic arms exist. This Project proposes integrating these arms into RTT mobile platforms for welding. This allows these platforms to be brought to the most common ship welds: collars, clips and erection welds. These mobile welding platforms can augment existing compartment workers and significantly improve productivity and safety.
The goal was to:
- Demonstrate system prototype in operational environment
