This paper deals with design solutions for a modular mechatronic demonstrator with video feedback used in research and education. The Demonstrator allows the testing of control algorithms on various mechanical structures with multiple degrees of freedom (DOF). Although simple in mechanical design, our setup offers a large number of possibilities both in research and education. It is our aim, with this demonstrator to test model based and also model free control strategies comparable to human behavior. For this paper we will construct a 2 DOF arm as the mechanical structure to be controlled. Our hypothesis is that a human does not require knowledge on its arm kinematics in order to perform tasks, thus we present in this paper an approach on determining the arm configuration to reach a target point without knowing the arm’s elements lengths.
Mechatronics is a new methodology used to achieve an optimal design of an electromechanical product. This methodology is collection of practices, procedures and rules used by those who work in particular branch of knowledge or discipline. Education in mechatronics at the Polytechnic University Timisoara is organized on three levels: bachelor, master and PhD studies. These activities refer and to design the mechatronics systems. In this context the design, implementation and experimental study of a family of mechatronic demonstrator occupy an important place. In this paper, a variant for a mechatronic demonstrator based on the combination of the electrical and mechanical components is proposed. The demonstrator, named humanoid robot, is equivalent with an inverted pendulum. Is presented the analyze of components for associated functions of the humanoid robot. This type of development the mechatronic systems by the combination of hardware and software, offers the opportunity to build the optimal solutions.
