Abstract
This paper proposes an evaluation index of global performance for agricultural robots. In general, it is not feasible to apply the theoretical field capacity to agricultural robots that have a high degree-of-freedom mechanism and high level of interaction with the working environment. In this paper, a macroscopic environmental model is first proposed. Second, fundamental equations of the working space and the working time are derived based on the environmental model and a normative task plan. Third, a new evaluation index is proposed based on these fundamental equations. The proposed index, which extends theoretical field capacity, is confirmed to be effective for evaluation of the performance of agricultural robots.
