A micro robotic positioning system is extremely important in many fields including: life sciences, photonics, microelectronics, and safety/security. Currently all commercial micro robotic system fall into one of three main classes depending on motor type: stepper-motor, vector-motor or DC servo-motor. LILEYA’s newly developed precision micro robotic PRS-3 is unique software controlled positioning system incorporating a proprietary direct-drive motors coupling mechanism. The PRS-3 does not use a conventional electromagnetic motor; instead it uses an advanced piezoelectric motor. As a result it is superior micro robotic system that eliminates the well know disadvantages of all previous robotic technology, while at the same time providing other intrinsic advantages.

Innovative Aspect and Main Advantages

Being designed on the basis three rotary axes – vertical axis “1” piezoelectric motors PM-22RS, horizontal axis “2” piezoelectric motor PM-22RS, horizontal axis “3” piezoelectric motor PM-20RS ( such system provides large displacement range and high accuracy. The PRS-3 micro robot works on a direct drive principle in which the rotary motion of piezoelectric motor is directly coupled to the other piezoelectric motor. The combination of high torque, self-braking torque, variable speed and high angular resolution provide accurate positioning and superior dynamic performance.

Areas of Application

LILEYA’s advanced micro robotic piezoelectric system PRS-3 is designed to meet a variety of positioning needs for the scientific, biotechnology, medical, semiconductor and industrial markets. It is suitable for applications such as: electrophysiology, e.g. patch clamping, microinjection, microscopy, microsurgery, microchip probing, rework and prototyping, laser and fiber optic alignment, X-Ray orientation, ultra-fine assembly, probing, soldering & testing, remote control. The unique positioning capabilities of PRS-3 and its miniature size means that it has important applications in many fields of science, engineering, medicine and manufacturing, where all too often the traditional methods of positioning tools rely upon standard X,Y,Z micropositioner systems.
