介绍了一种单从机械玩具的运动特征合成机械玩具的新方法。设计人员指定每个刚性特征组件的几何形状和随时间变化的旋转和平移。我们的算法自动生成一个机构组件，该组件位于产生指定运动的特征库下方的框中。组件中的部件是从参数化的集合中选择的，包括皮带轮、齿轮、曲柄滑块、快速返回和各种凸轮（螺形、椭圆形和双椭圆形）。这些零件的位置和参数经过优化，以产生指定的运动，最大限度地减少简单的复杂性，并在驱动轴上产生零件的均匀分布布局。我们的解决方案使用了一个特殊的初始化过程，然后是模拟退火，以有效地搜索复杂的构型空间以获得最优装配。
We introduce a new method to synthesize mechanical toys solely from the motion of their features. The designer specifies the geometry and a time-varying rotation and translation of each rigid feature component. Our algorithm automatically generates a mechanism assembly located in a box below the feature base that produces the specified motion. Parts in the assembly are selected from a parameterized set including belt-pulleys, gears, crank-sliders, quick-returns, and various cams (snail, ellipse, and double-ellipse). Positions and parameters for these parts are optimized to generate the specified motion, minimize a simple measure of complexity, and yield a well-distributed layout of parts over the driving axes. Our solution uses a special initialization procedure followed by simulated annealing to efficiently search the complex configuration space for an optimal assembly.
