The advancement of robotic technology in the agricultural industry is continually progressing with research, development, and practical applications in agricultural machinery. However, a crucial factor for the widespread acceptance of these machines is ensuring their safety. To date, risk analysis has been conducted on the basis of unmanned work in the agricultural field and troublesome cases using vehicle-style robotic agricultural machinery. Moreover, necessary safety requirements have been identified for both hardware (Machine) and software (Operation & management) components. Furthermore, safety standards, guidelines, and evaluation methods have been established to guarantee the safety of robotic agricultural machinery.
