A Review on Dual-Arm Manipulation in Agriculture

This article systematically reviews the literature on major components (application, platform, and control mechanism) of dual-arm robots in agriculture. To achieve an insightful and transparent review, four research perspectives (RPs) were defined from the perspective of the dual-arm component: tasks, platforms, controls, and future directions. Following the RPs, the structure and flow of this review are derived. By highlighting the RPs, this review article aims to identify the current research state and gaps in dual-arm agricultural robots. In this phase, the characteristics and challenges of agricultural tasks, meaningful platform design in terms of mobility, adaptability, and performance, cutting-edge sensing technologies, and advanced control strategies are also indexed. Based on these, promising future directions have been suggested for advances such as tactile guidance and scene understanding. This study will help related researchers gain scalable and improvable insights into dual-arm agricultural robots in dealing with practical challenges. The insights generated from this analysis could be utilized in the agricultural automation industry, helping to respond promptly to the growing needs of sustainable and innovative agriculture.
