A novel motion coordination method for variable-sized multi-mobile robots Research Article

Zichao XING, Xingkai WANG, Shuo WANG, Weimin WU, Ruifen HU,zcxing@zju.edu.cn,wmwu@iipc.zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4, Pages 521-535 doi: 10.1631/FITEE.2200160

Abstract: s (MMRSs) are widely used for transportation in industrial scenes such as manufacturing and warehousing. In an MMRS, is important as collisions and deadlocks may lead to losses or system stagnation. However, in some scenarios, robot sizes are different when loaded and unloaded, which means that the robots are variable-sized, making more difficult. The methods based on zone control need to first divide the environment into disjoint zones, and then allocate the zones statically or dynamically for . The zone-control-based methods are not accurate enough for variable-sized multi-mobile robots and reduce the efficiency of the system. This paper describes a method based on , which can dynamically avoid collisions and deadlocks according to the roadmap structure and the real-time paths of robots. Dynamic features make this method directly applicable to various scenarios, instead of dividing a roadmap into disjoint zones. The proposed method has been applied to many industrial projects, and this study is based on some manufacturing projects for experiments. Theoretical analysis and experimental results show that the proposed algorithm is effective and efficient.

Abstract:

The rapid development of the automobile industry brings substantial environmental challenges to China. Therefore, integrated development strategies targeting both the automobile industry and emission control, although difficult, are essential. Based on a localized model, this paper analyzes the characteristics of and historical trends in China's vehicle emissions and quantifies future trends under various emission control scenarios. The research summarizes and combs the bottlenecks and main contradictions in the process of synergetic development of China's future automobile industry and environmental improvement, puts forward the roadmap for the synergetic development applicable to China, and gives corresponding development proposals and control strategies.
