Abstract：[Significance]As special operation equipment in the full-life-cycle operation and maintenance system of pipelines,oil and gas pipeline robots are required to perform inspection,maintenance,and repair tasks under harsh working conditions such as high temperature,high pressure,and corrosive media.In view of the autonomy issues such as jamming faced by fully passively driven robots,and based on differences in speed control mechanisms,robots are categorized systematically into types such as braking control,bypass control,and self-driven control,and the body structure,motion control methods,and algorithms of various robots are summarized,aiming to clarify their technical characteristics and application limitations.[Analysis]Firstly,the current development status of speed control technologies for oil and gas pipeline robots at home and abroad was systematically summarized.Secondly,a comparative analysis was conducted focusing on the mechanical structure design,dynamic modeling methods,control strategies,and performance in pipeline anti-jamming,inspection,and positioning of braking-controlled,bypass-controlled,and self-driven controlled robots.Finally,based on current research progress,the development trends of oil and gas pipeline robots in structural modularization and control algorithm coordination were summarized,and prospects for future research directions were proposed.Through a multi-perspective review,this study provides reference and technical support for promoting the development of oil and gas pipeline robots towards intelligence and self-adaptation.
