Application of Arduino Module to Research in Surface Physics

Abstract

During the semiconductor or graphene wafers surface were investigated, the Arduino module was applied to control the impact point of the laser beam. While the pulse signal of laser beam impacts to surface selected material and the material is exposed to enough strong magnetic field, the photomagnetoelectric effect takes place. This causes the electrical signal in the measurement coil, which is connected to amplifiers. The paper presents application of Arduino UNO module to control the position in two dimensions (in the XY plane) of investigated silicon or graphene wafers while the photomagnetoelectric effect is measuring. The Arduino drive (through the integrated circuit with power transistors) the steps and shift of a dedicated table with a sample situated at the top of the table. Constructed equipment, based on Arduino board, allows for one step size of 1.25 μm in X-axis and Y-axis, and in effect, the each square millimeter contains 640000 measurement points. We are able also to modify the Arduino program for motors controller any moment. Moreover, it is also possible to apply the obtain method to investigate another semiconductor materials. The commercially available similar devices don’t have all need functions and they are incomparably more expensive.

Determining the arm's motion angle using inverse kinematics models and adaptive neuro-fuzzy interface system

“…Recently, the development of technology in robotics is a very serious concern, especially in the role of robots in dangerous environments such as space exploration [6], [7], firefighting [8], or industrial robots [9], [10]. One robot that is widely used is a mobile manipulator robot [11] specifically designed to take and move objects from one place to another [12]- [15]. In this case, kinematic motion analysis needs to be studied so that the arm moves on target, precisely, and accurately.…”
