...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...

.... At the same time, model-free RL has also shown success in specific soft robot tasks. For instance, a Q-learning-based visual servoing method enabled target search in unstructured environments by a soft robot (Liu et al., 2020), and Deep Q-Networks were used to achieve attitude control of a single arm...

...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...
