The vibrating plate has been extensively studied for objects manipulation. The manipulation is based on controlling the vibration modes, by which objects are generally trapped to nodal lines. However, it still remains a challenge for controlling desired nodal lines patterns. In this work, the vibration motor is proposed by operating multi-frequency rotatable bending modes with cross-like nodal lines. Then, the rotary and morphology manipulation characteristics are realized by precisely trapping objects to the cross-like nodal lines at arbitrary rotation angles. Firstly, we use the metastructure, which is connected by multiple plates, to expand the vibration eigenmodes with the same nodal lines patterns in different directions. Then, the vibration motor is realized by operating the rotary of multi-frequency bending modes in form of cross-like nodal lines. Furthermore, the metastructure vibration motor exhibits morphology of multiple particles assemblages with collection, and rotation through switching different rotatable vibration modes. Finally, the rotary manipulation for different objects such as a long stick is realized by the vibration motor. This work paves a way for the control of complex vibration modes, thereby enabling the vibration motor, and particles self-assembly.

振动板已被广泛研究用于物体操纵。该操纵基于控制振动模式，通过该振动模式，对象通常被束缚在节点线上。然而，控制所需的节线图案仍然是一个挑战。在这项工作中，提出了一种振动电动机，该电动机是通过使用十字形节线运行多频可旋转弯曲模式来提出的。然后，通过以任意旋转角度将对象精确地捕获到十字形节点线上来实现旋转和形态处理特性。首先，我们使用由多个板块连接的亚结构，以相同的节点线模式在不同方向上扩展振动本征模。然后，振动电机是通过以十字形节点线的形式操作多频弯曲模式的旋转来实现的。此外，元结构振动电机表现出具有多个颗粒集合体的形态，具有聚集性，并且通过切换不同的可旋转振动模式而旋转。最后，通过振动马达实现对诸如长杆之类的不同物体的旋转操纵。这项工作为控制复杂的振动模式铺平了道路，从而使振动电机和颗粒自组装成为可能。
