Resumen AbstractEn este artículo se presenta un acercamiento al mando a distancia de un robot móvil que emplea un telé-fono inteligente para comandarlo. La idea principal es recolectar los datos generados por el acelerómetro incluido en el teléfono inteligente. Los datos son los resultados de mover el teléfono en la dirección de los ejes Y y Z. Tales datos serán usados para entrenar dos redes neuronales que definirán la dirección del movimiento del robot móvil. Las salidas obtenidas de las redes neuronales serán procesadas para calcular y trazar la trayectoria, que es determinada por el modelo cinemático para un robot móvil tipo triciclo.This paper presents an approach to remote control a robot using smartphone. The main idea is to collect data generated by the accelerometer sensor included in the smartphone. The data are the results of moving the smartphone in direction of the axis Y and Z. Such data will be used for training two neural networks that will define the direction of the movement of the mobile robot. The outputs obtained from the neural networks will be processed to compute and plot the trajectory, which is determined by the kinematic model for a tricycle mobile robot.Palabras clave: sistemas remotos, redes neuronales, robot móvil, teléfono inteligente, acelerómetro.

Remote Operation of CeCi Social Robot

“…Mobile devices are among the most used equipment by people in today's world, and 80% of them run on this operating system [34]. Smartphones allow the use of available technology at a low cost due to several functionalities capable of replacing a computer in several aspects [35]. It is even possible to take advantage of these devices used to control a robot through Bluetooth [36,37] and a wireless interface providing a high-speed bidirectional connection.…”

Evaluation of a teleoperated vehicle for educational purposes

“…The H-bridge module implemented in the vehicle is a printed circuit at the Center for Research in Microelectronics (CIME) based essentially on the use of two transistors and two relays for each motor to control (Figure 9) [16]. This design has as a disadvantage over very popular commercial models, such as the L298N driver [2], [3], [8], the impossibility of controlling the speed of rotation; on the other hand, it has as advantages the control of four motors from the same circuit (the L298N allows the control of two DC motors from the same circuit) and a better use of the voltage provided by the battery (the L298N has internal voltage drops of more than 1V due to switching transistors that are not present in the module implemented in the project [8]). The motors are powered from the battery that energizes the vehicle and the stimuli are made with the digital pins of the Arduino UNO.…”
