Modelling and Robust Position/Force Control of a Piezoelectric Microgripper. [PDF]
International audienceThis paper deals with the control of a piezoelectric microgripper based on two piezocantilevers. To avoid the destruction of the manipulated micro-object and to permit a high accurate positioning, the microgripper is controlled on ...

Design and Validation of a Single-SOI-Wafer 4-DOF Crawling Microgripper
This paper deals with the manipulation of micro-objects operated by a new concept multi-hinge multi-DoF (degree of freedom) microsystem. The system is composed of a planar 3-DoF microstage and of a set of one-DoF microgrippers, and it is arranged is such

Compliant microgripper using soft polymer actuator
Miniaturization of robotic grippers enables precise manipulation of small-size objects. However, most microgrippers are actuated by rigid actuators, and thus retain challenges such as micro-fabrication, complex structure, and lack of compliance. Here, we

Development of Microgripper System with Multiple Degrees of Freedom
本文提出一具有四個自由度之微夾爪,其每一指可由壓電雙層驅動器而分別作出上下及左右之運動,達到多自由及微米精度之需求。 藉由Euler-Bernoulli及更精確之Timoshenko原理建構出靜態模型,並求得微夾爪之最大位移與最大出力。由結果可得,二者並無太大差別,Euler-Bernoulli模型亦可適用於精密控制方面。 動態模型則包含致動與感測方程式二者可獲得輸入電壓與輸出位移之關係。利用動態模型設計一前饋和回饋混合型控制器以達到微米精度之控制 ...

Design and microfabrication of a constant-force microgripper
The characterization process of micro- and submicrometre particles in some cases demands their careful handling and placement. In most cases, a well-designed microgripper can address these requirements.

Development of Micro-Grippers for Tissue and Cell Manipulation with Direct Morphological Comparison
Although tissue and cell manipulation nowadays is a common task in biomedical analysis, there are still many different ways to accomplish it, most of which are still not sufficiently general, inexpensive, accurate, efficient or effective.
