Development of biotechnology and technologies related to small size object position and placement in working area, ensuring desired orientation and fitting during movement into prescribed positions. Paper provides an effort to classify and provide a sorted list of applications in the variety of existing robotic systems to manipulate the object of micrometric size. Extensive development of robotic systems fosters intensive request of accurate and fast drives for robots and manipulators. Paper overviews and specifies a broad spectrum of micrometric scale drives, operating under certain physical effects. These drives are analyzed according to their physical domain, movement mode, stroke or angle range, generated force, speed of movement and other essential drive parameters. The paper concludes a high potential of drives development and points direction to future their application possibilities in microrobotics.

“…Recent progress has been made in the research of micro-actuators and they are becoming key component of some micro-robots and high-precision equipment [1][2][3]. Micro-actuators contain a variety of driving principles, which can be mainly divided into electrostatic [4], piezoelectric [5,6], electromagnetic [7,8], thermal electricity [9]. Electrostatic actuators are compatible with fabrication processes of integrated circuit technology, and they have advantages of simple structure and high energy efficiency.…”

This paper introduces the design, fabrication and characterization of a micro electromagnetic linear actuator integrated with magnetic guide. The actuator consists of a slider, a stator and a magnetic guide. A magnetic guide is used to replace the mechanical rail of conventional linear actuator to ensure the linear motion and to avoid friction. The purpose of this paper is to study the influence of magnetic guide on the dynamic characteristics of electromagnetic linear actuator and measuring techniques for micro-actuators. To test the resistance to motion and output thrust force of the actuator, a cantilever type force sensor is proposed, which can measure the small force in ~mN order, and the measurement error is less than 3%. Using this sensor, the output thrust measured is higher than 10mN when 1A current is applied, and the friction force of the actuator measured is about 7.73mN. Two-phase square wave and sine wave current are used to drive the actuator, the minimum driving current and frequency of the actuator are less than 0.1A and 1Hz respectively. The actuator attains a maximum stable moving speed of 0.15m/s with the input signal frequency of below 250Hz. In addition, the anti-interference capability of the actuator is evaluated through simulations and experiments. These results show that the actuator can bear an interference 45 times its own gravity in the directions that are perpendicular to the moving freedom, and can adjust the direction of motion automatically when the rotation angle in three orthogonal directions is less than 6 °.
