ABSTRACT Supernumerary robotic limbs are a new approach to field‐oriented human augmentation, in which extra robotic limbs are attached to the human body to extend its workspace, add degrees of freedom, and support tasks beyond natural human abilities. In contrast to existing reviews that primarily focus on qualitative descriptions, this work provides a comprehensive, quantitative analysis of SRLs design and employment. For the first time, this review examines the interrelationships among SRL applications, targeted limbs, actuation, human movement intention recognition, environmental perception, feedback methods, and control strategies. The analysis adopts dual perspectives of application‐driven and limb‐targeted design, offering actionable insights for both laboratory research and field deployment. Additionally, methods for integrating SRLs into the human body schema are comprehensively explored. Finally, based on this quantitative analysis, this review identifies emerging trends and challenges, offering critical insights poised to accelerate the next wave of SRL development and push the boundaries of human augmentation.
