Robotic handling of objects in the micro-world is a challenging problem. Due to the natural differences between micro-manipulation and robotic manipulators, it is difficult to produce such a micro-hand which can function as robotic hands in the physical world. In this letter, we propose a robotic ha
The Brownian motion of micro-objects in fluid mediums is a fundamental distinction between optical manipulation and robotic manipulation in the macro-world. Besides, current control techniques for optical manipulation generally assume that the manipulated micro-objects are initially trapped prior to
Existing control systems for optical manipulation of multiple micro-objects do not allow users to interact with the systems during manipulation to deal with unexpected events, while ensuring stability of the overall control systems. In this paper, we propose a robotic control technique for human-gui…
Current control techniques for optical manipulation of multiple micro-objects employ laser tweezers to directly trap and manipulate the target microscopic objects, and thus it is not capable of coordinating and manipulating micro-objects with arbitrary types in the micro-world, including large micro…
Existing control techniques for optical trapping of cells or micro-objects can only perform either positioning control or separate control of orientation and position in a sequential manner. In this paper, we propose a robotic control technique to achieve simultaneous orientation and positioning con…
In existing control techniques for optical manipulation, the effect of the Brownian motion is usually disregarded for ease of analyzing the control systems. However, due to the prevalence of the Brownian motion and its effect on micro-manipulation of tiny objects, it is important for the Brownian ef
Existing control techniques for optical tweezers utilize a single focused laser beam to directly trap and manipulate a target cell. However, a typical force generated by an optical trap is extremely small (few pico-newtons) and therefore it is not sufficient to manipulate a larger cell or object. Th…
