Analysis of Kinematics of Mechanisms Containing Revolute Joints
Kinematics of rigid bodies can be analyzed in many different ways. The advantage of using Euler parameters is that the resulting equations are polynomials and hence computational algebra, in particular Gröbner bases, can be used to study them. The disadvantage of the Gröbner basis methods is that the computational complexity grows quite fast in the ...

Extended and Unscented Kalman Filtering Applied to a Flexible-Joint Robot with Jerk Estimation
Discrete Dynamics in Nature and Society, 2010 Robust nonlinear control of flexible-joint robots requires that the link position, velocity, acceleration, and jerk be available. In this paper, we derive the dynamic model of a nonlinear flexible-joint robot based on the governing Euler-Lagrange ...

Application of the ADAMS program to deployable space truss structures [PDF]
The need for a computer program to perform kinematic and dynamic analyses of large truss structures while deploying from a packaged configuration in space led to the evaluation of several existing programs. ADAMS (automatic dynamic analysis of mechanical

International Journal of Advanced Robotic Systems, 2014 This paper presents a new end-effector as a key component for a robotic needle insertion-type intervention system and its kinematic analysis. The mechanism is designed as a spherical mechanism with a revolute joint and a curved sliding joint, and its ...
