...Dejun Zheng; Jianzhong Hu; Qianfei Zhou; Feiyun Xu; Yuegui Feng Purpose The purpose of this study is to address the challenge that accurate recognition of industrial robot operational states from noisy long-sequence current signals remains difficult, as feature representations are easily degraded...

... in unstructured environment and put forward the visual positioning and grasping strategy that can be used in industrial robot cell. Design/methodology/approach A multikeypoints detection network Binocular Attention Hourglass Net is constructed, which can complete the two-dimensional positioning of the left...

... of the robot’s positioning error, the Kolmogorov test was used. Findings – In this paper, it has been demonstrated theoretically and experimentally that the industrial robot accuracy can vary over a very wide range in the workspace. This provides an additional opportunity to increase reliability...

... and this results in a significant reduction of the number of unknowns to be estimated, while the predefined DCT trajectory bases can approximate most real trajectories compactly (Akhter et al., 2011). Assembly Industrial robot Camera Moving workpiece Synchronisation concept Trajectory...
