我们研究了如何在非线性介质中使用时空动态来实现对象的分布式操纵 - 在令人兴奋的介质中，通过波 - 弗朗特和模式进行定位和运输对象。令人兴奋的介质的细胞 - 自动对机模型。我们分析了基本平面形状的运动（最初沿轴对齐或随机对准），由激动人心的晶格控制着各种令人兴奋的晶格。就平面形状的明智的非平凡操纵而言，巨大的潜力。
We study how to employ space-time dynamics in nonlinear media to achieve distributed manipulation of objects — positioning, orienting and transporting objects by wave-fronts and patterns in excitable medium. We present the results of computational experiments of a massive parallel actuator controlled by a cellular-automaton model of an excitable medium. The model incorporates closed-loop actuation where sites of the medium can be excited not only by their closest neighbors but also by the edges of the manipulated object. We analyze motion of basic planar shapes (either initially aligned along axes or randomly oriented) induced by an actuator controlled by excitable lattice with various excitation rules. We demonstrate that space-time excitation dynamics in discrete nonlinear media bears a huge potential in terms of sensible nontrivial manipulation of planar shapes.
