Este artículo presenta el diseño e implementación de una plataforma móvil autónoma para la investigación de algoritmos inteligentes, enfocada a la formación en ciencias de la computación a través de la robótica. El prototipo se elaboró sobre una estructura en acrílico soportada con una rueda omnidireccional y dos ruedas acopladas a sus correspondientes motores de DC dotados de caja de reducción, cada una con sensores de velocidad para permitir el control de movimiento del sistema. Como unidad central se configuró y programó la tarjeta Arduino Leonardo, la cual interconecta el sistema de movimiento, los sensores de detección de obstáculos y un arreglo de sensores que constituyen el módulo seguidor de línea. Todos estos componentes se encuentran repartidos en la estructura de tal forma que permiten la interoperabilidad de los mismos y la coordinación de sus funciones.AbstractThis paper presents the design and implementation of an autonomous mobile platform for the research of intelligent algorithms, focused on training in computer science through robotics. The prototype was made on an acrylic structure supported with an omnidirectional wheel and two wheels coupled to the corresponding DC motors provided with reduction box, each with speed sensors to allow motion control system. As a central unit was configured and programmed the Arduino Leonardo card, which interconnects the motion system, sensors obstacle detection and an array of sensors that make up the line follower module. All these components are distributed in the structure such that allow interoperability of these and coordinate their functions.

In this report, a new-type two-joint articulated hopping robot with two stopper mechanisms is developed. The two rotary joints are actuated by two DC motors with reduction gears. In this new-type two-joint articulated hopping robot with two stopper mechanisms, the hopping motion actions are achieved by the two joint rotational dynamics and the two stopper mechanisms. Using the two stopper mechanisms, the angular momentums and momentums of the two links are transformed into the hopping motion action according to the law of conservation of angular momentum and momentum. Then, the hopping motion control system is constructed to fit the DC motor characteristics, and the effects of the stopper settings and the delay time of the control voltage of the DC motor on the hopping motion performance are experimentally investigated. Furthermore, the examples of the hopping motion control experiments are demonstrated, and it is confirmed that the forwards and backwards hopping motion actions can be successfully performed.

This paper presents the development of a piano-playing robot in order to provide people a means of entertainment. The design and development of this project includes two parts: the design of a dexterous hand for manipulating a piano and a linear motion control system. The paper first discusses the design of dexterous hand. Then, a motion control solution is determined, a linear railing along with a rack and pinion gear are applied to produce the linear motion. Also, in order to improve the control performance of the linear motion system, the Extended Kalman Filter (EKF) Algorithm is adopted. Finally, a flow chart of the control system is presented. Experimental results show that the piano robot can play designated notes.

In the last years, many researches have proposed concerning the motion control and position regulation for manipulators. Motion control has important applications in many areas, for example industrial robotics. In this paper control system based on digital controller for the position control of robotic arm manipulator are build. The proposed control system was simulated on a robot manipulator driven by permanent magnet dc motors. Simulation results show the effectiveness of the control approach.
