Edge Intelligence for Robotics: A Comprehensive Survey on Key Technologies, Trends, and Applications in Industrial Robots, UAVs, and Multirobot Systems

Edge computing (EC) is revolutionizing robotics by bringing computation closer to the data source, reducing latency and overcoming the limitations of cloud-based systems. This paradigm shift is essential as the number of connected devices and data volumes surge, especially with the advent of 5G networks. This paper provides a comprehensive survey of key technologies in edge computing for robotics, including industrial robots, UAVs, and multi-robot systems. We examine the integration of edge intelligence with AI, enabling real-time decision-making and enhanced processing efficiency while addressing challenges like mobility, security, and data privacy. Additionally, the paper explores case studies in autonomous navigation, industrial robotics, and UAV-based IoT applications, highlighting the benefits and challenges of implementing edge AI in diverse robotic systems. Through this survey, we aim to identify promising research directions and practical applications to accelerate the deployment of edge intelligence in robotics.
