...Yixuan Zhou; Yifan Zhou; Hesheng Wang Purpose Visual servoing is a guaranteed high-precision robotic control scheme but inevitably encounters several constraints. This paper aims to propose a planner yielding feasible feature trajectories, accounting for physical and image constraints...

... policies mapping visual observations to motions. Deep reinforcement learning can directly map raw images to actions, but often needs retraining when observations change (Ladosz et al., 2022 ; Wang et al., 2022). Instead, we formulate a distance-oriented visual servo problem, where the RL...

...Chicheng Liu; Libin Song; Ken Chen; Jing Xu Purpose This paper aims to present an image-based visual servoing algorithm for a multiple pin-in-hole assembly. This paper also aims to avoid the matching and tracking of image features and the remaining robust against image defects. Design...

...Hua Liu; Weidong Zhu; Huiyue Dong; Yinglin Ke Purpose To gain accurate support for large aircraft structures by ball joints in aircraft digital assembly, this paper aims to propose a novel approach based on visual servoing such that the positioner’s ball-socket can automatically and adaptively...

...Yu Qiu; Baoquan Li; Wuxi Shi; Yimei Chen Purpose The purpose of this paper is to present a visual servo tracking strategy for the wheeled mobile robot, where the unknown feature depth information can be identified simultaneously in the visual servoing process. Design/methodology/approach...

...Hua Chen; Lei Chen; Qian Zhang; Fei Tong Purpose The finite-time visual servoing control problem is considered for dynamic wheeled mobile robots (WMRs) with unknown control direction and external disturbance. Design/methodology/approach By using finite-time control method and switching design...
