Parallel robot motion planning
Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002A fast, parallel method for computing configuration space maps is presented. The method is made possible by recognizing that one can compute a family of primitive maps which can be combined by superposition based on the distribution of real obstacles.

Effective workspaces of parallel robots
Robotica, 2022AbstractAn approach for calculating the effective workspaces of parallel mechanisms has been considered in this paper. The effective workspace is a set of reachable by the end-effector points, where an important parameter (or parameters) from the point of view of operation is not higher than critical.

Robust control of a parallel robot
2015 International Conference on Advanced Robotics (ICAR), 2015This work presents the implementation of two model based control schemes in parallel mechanisms; the H∞ robust control designed by the mixed sensitivity approach and the Computed Torque Control (CTC). Simulations results are illustrated for the 3DOF parallel robot namely the “Delta robot”. Performances of the CTC and the H∞ controllers are compared for

Parallel topology robot calibration
Robotica, 1997A calibration method for a Stewart platform has been developed as part of a project aimed at developing a calibration method for a Delta robot. The Delta has 3 degrees of freedom (DOF) but is more complex than the Stewart platform for calibration purposes because an extra link is inserted in each kinematic chain between the base and the Nacelle member.

Isoelastic behavior of parallel robots
Robotica, 1989SUMMARYThis paper presents a particular architecture of a parallel robot which is characterized by a diagonal stiffness matrix. This result suggests the use of a parallel robot in the final phase of insertion as a passive compliance device. The stiffness rate of this device is controlled by the gain of the feedback loop.

A robust adaptive control of a parallel robot
International Journal of Control, 2010The work presented in this article deals with the robust adaptive control tracking of a 6 degree of freedom parallel robot, called C5 parallel robot. The proposed approach is based on the coupling of sliding modes and multi-layers perceptron neural networks (MLP-NNs). It does not require the inverse dynamic model for deriving the control law.

Speech recognition in parallel robots
Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence, 2019China's current aging is getting higher and higher. In Shanghai alone, the number of elderly people over 60 years old is close to 8.5 million, of which 4.7% are old people who cannot take care of themselves. In addition, there are a large number of disabled people caused by accidents and diseases.Relying on caregivers alone cannot meet the care needs ...
