Precise control is of importance for robots, whereas, due to the presence of modeling errors and uncertainties under the complex working environment, it is difficult to obtain an accurate dynamic model of the robot, leading to decreased control perfo

This paper presents a three-degree-of-freedom fully parallel robotic wrist and its preliminary kinematics. This mechanism actuated by spherical four-bar linkages originates from a spherical parallel manipulator with co-axial inputs. The inequalities

Due to the characteristics of non-linear, non-stationary and background noise interference in rolling bearing fault signals, the extraction of fault features becomes very complicated. To solve this problem, this paper proposes a rolling bearing fault
