Abstract: The computation of the angular acceleration of a rigid body from measurements of accelerations of three noncollinear points of the body is presented in this paper. This is based on algorithms ...

Abstract: This paper follows a previous one on the computation of the screw parameters of rigid-body motions defined by two finitely-separated positions. The subject of the present paper is the computation ...

Abstract: Introduced in this paper is a novel approach that leads to efficient algorithms for computing the screw parameters of rigid-body motions. This is based on invariants associated with the said ...

Abstract: As shown in this paper, when designing parallel manipulators for tasks involving less than six degrees of freedom, the topology can be laid out by resorting to qualitative reasoning. More ...

Abstract: Within the European SESAME project, extensive experimental work was performed and complemented by the development, application, and validation activities of thermal-hydraulic simulation tools for different scales. The ...

Abstract: The authors propose a systematic formulation of the dynamics of the 6-P-RR-R-RR parallel-kinematics machine (PKM) with offset RR -joints. The kinematics of the same system is reported in an accompanying paper. Based on the ...

Abstract: The parametrization of a rigidbody rotation is a classical subject in rigidbody dynamics. Euler angles, the rotation matrix and quaternions are the most common representations. However, Euler angles are known to be prone ...

Abstract: The control of multiple manipulators handling a common object entails the solution of an underdetermined system of linear equations which represents the system’s dynamics. In order to choose an ...

Abstract: In this paper, the design of a spherical three-degree-of-freedom parallel manipulator is considered from a kinematic viewpoint. Three different design criteria are established and used to produce ...
