受最近分子电机实验的启发，提出了一种柔性机器的动力学系统模型，它将注入的能量转换为输出的定向运动。正如实验中那样，输出量分布广泛，因此输入能量和输出运动之间的耦合是松散的。这种能量转换被证明对周围环境的变化具有鲁棒性。对模型不动点解进行了稳定性分析，表明由时间三体运动引起的瞬态混沌运动与能量转换有关。
Inspired by recent experiments of molecular motors, a dynamical systems model for a flexible machine is proposed which converts injected energy to output directional motion. The output amount is distributed broadly, and thus the coupling between input energy and output motion is loose, as in the experiments. This energy conversion is shown to be robust against the change of surrounding environment. Stability analysis on the fixed point solutions of the model is presented, which suggests that transient chaotic motion, induced by temporal three-body motion, is relevant to the energy conversion.
