Mechanisms of Emergent Computation in Cellular Automata

We introduce a class of embedded-particle models for describing the emergent computational strategies observed in cellular automata (CAs) that were evolved for performing certain computational tasks. The models are evaluated by comparing their estimated performances with the actual performances of the CAs they model. The results show, via a close quantitative agreement, that the embedded-partic...

Composition of spherical four-bar-mechanisms

We study the transmission by two consecutive four-bar linkages with aligned frame links. The paper focusses on so-called “reducible” examples on the sphere where the 4-4-correspondance between the input angle of the first four-bar and the output-angle of the second one splits. Also the question is discussed whether the components can equal the transmission of a single four-bar. A new family of ...

Interval Propagation for Solving Parallel Spherical Mechanisms

An interval propagation method for spherical kinematic loops is used in a branch and prune algorithm to solve the direct kinematics of parallel spherical mechanisms. The algorithm finds all solutions with a desired resolution. The use of specific properties of the rotation equations involved allows the method to be more efficient than more general algorithms for this problem.

Singularity Analysis of Single-dof Spherical Mechanisms Using Instantaneous Poles

Instantaneous poles are the spherical counterparts of instant centers; however, they are not completely used to study the kinematic behavior of spherical mechanisms. Instantaneous kinematics of a mechanism becomes undetermined when it is in a singular configuration (singularities); this indeterminacy has undesirable effects on static and motional behavior of the mechanism, so these configuratio...

Systematic Process for Constructing Spherical Four-bar Mechanisms

This paper presents a methodology for constructing spherical four-bar mechanisms with an emphasis on utilizing simpler machining processes and part geometries. By building each link out of easily created pieces instead of a single complex shape, a mechanism can be quickly prototyped and tested. The paper discusses the benefits and some of the issues that need to be addressed by this approach. S...
