These additional costs have to be recovered from faster return of investment, Service robot systems and humanoid construction robots. The assembly of complex structures may need specific parts. Areas are identified where cyber-physical systems can be applied, including intelligent and interconnected workflows where online process monitoring can be leveraged towards automated data acquisition and real-time diagnostics. While some may think using robotics in construction is a new development, it is actually the continuation of a larger story about automation in construction that goes back thousands of years.
