EEG theta and Mu oscillations during perception of human and robot actions. [PDF]

open access: yes, 2013
The perception of others' actions supports important skills such as communication, intention understanding, and empathy. Are mechanisms of action processing in the human brain specifically tuned to process biological agents?

A New Method for Displacement Modelling of Serial Robots Using Finite Screw

open access: yesMachines
Kinematics is a hot topic in robotic research, serving as a foundational step in the synthesis and analysis of robots. Forward kinematics and inverse kinematics are the prerequisite and foundation for motion control, trajectory planning, dynamic ...

Structural design and characteristic analysis for a 4-degree-of-freedom parallel manipulator

open access: yesAdvances in Mechanical Engineering, 2019
Previous studies on parallel mechanisms have been limited to symmetrical and semi-symmetrical parallel robots. However, there is relatively little research on asymmetrical parallel robot, especially on asymmetrical parallel robots with 4 degrees of ...

Kinematics and workspace analysis of a 3ppps parallel robot with u-shaped base [PDF]

open access: yes, 2017
This paper presents the kinematic analysis of the 3-PPPS parallel robot with an equilateral mobile platform and a U-shape base. The proposed design and appropriate selection of parameters allow to formulate simpler direct and inverse kinematics for the ...

Compliance error compensation technique for parallel robots composed of non-perfect serial chains [PDF]

open access: yes, 2012
The paper presents the compliance errors compensation technique for over-constrained parallel manipulators under external and internal loadings. This technique is based on the non-linear stiffness modeling which is able to take into account the influence

Direct Kinematics Solution of 3-RCC Parallel Robot using a Semi-Analytical Homotopy Method [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2019
Parallel robots are closed-loop mechanisms presenting very good performances in terms of accuracy, rigidity, and the ability to manipulate large loads. Inverse kinematics problem for most parallel robots is straightforward, while the direct kinematics is

An Efficient Stochastic Constrained Path Planner for Redundant Manipulators

open access: yesApplied Sciences, 2021
This brief proposes a novel stochastic method that exploits the particular kinematics of mechanisms with redundant actuation and a well-known manipulability measure to track the desired end-effector task-space motion in an efficient manner. Whilst closed-
