چکیده

This paper presents a new method for solving the direct kinematics problem of a general Stewart Platform by using three linear extra sensors. The sensors are disposed at a most general way, connecting the non-planar base and the planar mobile platform at distinct points. The extra sensory data enables to reduce the problem to the solution of an overdetermined system of 6 quadratic equations in 3 unknowns. Random numerical examples have demonstrated the existence of a unique solution to this system. # 1999 Elsevier Science Ltd. All rights reserved.

An inchworm locomotion device is presented that can walk on smooth terrain. It consists of a piezoelectric unimorph and two custom-designed legs. A mathematical model is formulated by superimposing the compliant and rigid-body components of the motion. The model is subsequently utilized to evaluate the ground reaction forces and horizontal velocity. Numerical simulation is performed to select t...

This paper presents a new discretization method for the computation of the orientation workspace of 6DOF parallel manipulators, de®ned as the set of all attainable orientations of the mobile platform about a ®xed point. The method is based on the use of a modi®ed set of Euler angles and a particular representation of the orientation workspace. In addition, the projected orientation workspace is...

Bennett’s linkage is a spatial 4R closed chain that can move with one degree of freedom. The set of relative displacement screws that form the one-dimensional workspace of this device defines a ruled surface known as a cylindroid. The cylindroid is generally obtained as a result of a real linear combination of two screws. Thus, the workspace of Bennett’s linkage is directly related to a one-dim...

This paper deals with solution methods of optimal synthesis of planar mechanisms. A searching procedure is defined which applies genetic algorithms based on evolutionary techniques and the type of goal function. Problems of synthesis of four-bar planar mechanisms are used to test the method, showing that solutions are accurate and valid for all cases. The possibility of extending the method to ...
